While creating this new handbook, we had our current customers in mind as well as prospective customers – and also our own staff. We gathered our own expertise together with some general principles and guidelines from the areas in which portable Portable Instrumentsare used. We hope that this will shed some light on the many and varied aspects of our sensors and portable gas detectors, so as to increase the safety in your place of work. Dräger has been involved for decades in the development and production of gas detection sensors and portable gas detection devices. This is a subject area in motion – “panta rhei,” as Heraclitus would have said – and the development is ongoing. Lots of innovative ideas have found their way into patents for sensors and gas detection devices. We have worked through, and continue to work through, lots of learning curves. And that is why it is always of tremendous benefit to gather the experience we have in the field of instrumentation together with our expertize in the development of sensors within one company. The demands placed on gas detection by the numerous standards and regulations are becoming more and more complex. We are continually having to adjust in order to increase safety levels and protect people’s lives. We hope that this handbook will provide you with a tool which will give you a quick, clear overview of the technologies we use – right down to the details. May this book prove to be a dependable companion! With best regards, Ulf Ostermann Portfolio Manager, Portable Instruments P.S. A special thank to all the hard-working people who helped to produce this handbook. 8| Properties of dangerous gases and vapors 2 Properties of dangerous gases and vapors Flammable and toxic gases and vapors occur in many areas. It is important to recognize the danger they pose – and that is the purpose of gas detection and warning devices. This handbook is meant to give a basic introduction to gas detection technology, measuring principles and safety concerns. 2.1 Gases – what is a gaseous matter? Matter at a temperature above its boiling point is referred to as a gas. In terms of the normal human environment, this means that all those substances whose boiling points at normal atmospheric pressure are below 20°C (68° F), are gases. The lightest gas is hydrogen (H2, fourteen times lighter than air), the heaviest gas (around ten times heavier than air) is tungsten hexafluoride (WF6). Under normal conditions, one cubic centimeter of gas contains thirty trillion molecules, whose average distance from one another is only around 3 nanometers. They move through space at between several hundred and several thousand meters per second but, at the same time, they collide with other molecules many billions of times each second. With the result that they only cover around 50–100 nanometers between impacts, and they continuously change their direction and transfer energy to the other molecules with which they collide. The result is a completely random molecular motion which in macroscopic terms can be measured as temperature (average kinetic energy of all the molecules) and pressure (the average force exerted on a surface by all the molecules hitting it), as well as volume (spatial extent). Pressure, temperature, and volume are always in a fixed relationship to one another, which is governed by external conditions. In an ideal situation, they obey what is known as the “ideal gas law,” namely: – At a constant pressure, their volume changes in proportion to their temperature – their volume increases when heated; – If the volume remains the same (for example, in a closed container), then their pressure changes in proportion to their temperature – for example, the pressure inside a container increases when heated; – At a constant temperature, pressure changes inversely proportion to volume – for instance, the interior pressure rises when gas is compressed. The extremely fast random movement of gas molecules is also the reason why they mix freely with other gases, never to become seperated again. This molecular behavior also explains the tendency of molecules to become less concentrated (diffusion), something which plays an important role in gas detection technology. Generally speaking, these processes become faster, the more quickly the molecules move (in other words, the hotter the gas is) and the lighter the molecules are (in other words, the lighter the gas is). |9 2.2 Vapors – aren’t they gases, too? Unlike gas – of which there are only perhaps between 200 to 300 – the word vapor is used to describe the gaseous state of a material below its boiling point. Vapor is always in equilibrium with its fluid (and sometimes solid) phase – it condenses and vaporizes according to the temperature. This is most familiar to us with water; when moist air near the ground cools down at night, ground mist forms (condensation) – but the warmth of the morning sun dissipates the mist (evaporation). In a closed container, a maximum vapor concentration always exists above the surface of a liquid, and this concentration is dependent on the temperature of the liquid. On a microscopic level, the vapor is a result of the random movement of the liquid’s molecules combined with their ability to overcome the surface tension and mix with the air molecules above the surface. Every liquid has a certain characteristic vapor pressure, which depends on its temperature and reaches atmospheric pressure when the liquid reaches its boiling point. A graphic depiction of this relationship is known as a vapor pressure curve, and it shows the maximum possible vapor concentration at any given temperature. Vapor pressure curve of liquid n-hexane 300 hPa 250 200 150 ST-1099-2008 100 50 0 -10 -5 0 5 10 15 20 25 30 35 ° C If you divide the maximum possible vapor pressure by the ambient pressure, you are given the saturation concentration in Vol.-% (volume percent). Hexane gas at 20°C or 68° F (vapor pressure 162 hPa or 2.35 psi) and an ambient pressure of 1,000 hPa (14.5 psi) has a maximum possible concentration of 16.2 Vol.-%. 10| Properties of dangerous gases and vapors 2.3 Our atmosphere Our atmosphere extends far out into space, getting less dense the more it stretches. The blue color of the sky is caused by the scattering of the sun’s rays on the air molecules in the atmosphere. The sky is actually already black by the time you reach a height of around 21 km (13 miles). If you were to subject the entire atmosphere to an even pressure of 1013 hPa (14.7 psi), then it would only be 8 km (5 miles) high, and the UV-absorbing stratospheric ozone layer would be a mere 3 mm (0.11 in.) high. Typical composition of the earth’s atmosphere in ppm: Composition Gas Principal gases N2 – nitrogen O2 – oxygen H2O – water vapor Ar – argon CO2 – carbon dioxide Trace gases Ne – neon He – helium CH4 – methane Kr – krypton H2 – hydrogen N2O – nitrous oxide CO – carbon monoxide Xe – xenon O3 – ozone Other trace gases Total dry humid 780,840 209,450 0 9,340 340 768,543 206,152 15,748 9,193 335 18 5 1.8 1.1 0.5 0.3 0.09 0.09 0.07 3.05 1,000,000 18 5 1.8 1.1 0.5 0.3 0.09 0.09 0.07 3.0 1,000,000 1 Vol.-% = 10,000 ppm; assumption for humid air: 68% r.h. at 20°C (68°F) The earth’s atmosphere has a mass of around 5 quadrillion metric tons (5.235 × 1018 kg), which weighs down on an area on the earth's surface of 0.507 × 1015 m2. This creates an atmospheric pressure on the earth’s surface of 10,325 kg/m2, which corresponds to normal atmospheric pressure: 1,013 hPa (14.7 psi). Atmospheric pressure decreases with increasing altitude: | 11 Altitude m/ft. Atmospheric pressure hPa/psi -1.000 (-3280.8) 1.148 (16.6) -500 (-1640.4) 1.078 (15.6) 0 (0) 1.013 (14.7) 500 (1640.4) 952 (13.8) 1.000 (3280.8) 900 (13.1) 1.500 (4921.2) 840 (12.2) Altitude m/ft. Atmospheric pressure hPa/psi 2.000 (6.561,7) 795 (11.5) 3.000 (9.842,5) 701 (10.2) 4.000 (13.123,3) 616 (8.9) 5.000 (16.404,2) 540 (7.8) 6.000 (19.685,0) 472 (6.8) 8.000 (26.246,7) 356 (5.2) The number of molecules in a given volume decreases with decreasing atmospheric pressure, which means that the results produced by partial pressure-measuring sensors are always dependent on the atmospheric pressure. More than 78 Vol.-% of the earth’s atmosphere is nitrogen, which is fully inert, and although available in excess, can not even be used as a much-needed fertilizer for plants. In contrast, highly reactive oxygen is fundamental to our breathing – more than that: it is the foundation of almost all life. Just under 21 Vol.-% of the atmosphere is oxygen. A lack of oxygen is life-threatening – and cannot be perceived by the human senses. Oxygen deficiency is generally caused by the release of an inert gas, which then in turn displace oxygen. Since the atmosphere is only around one fifth oxygen, the oxygen concentration is only reduced by around one fifth of the concentration of the inert gas. For example, if 10 Vol.-% of helium is released into the air then oxygen is reduced by 2 Vol.-% and the level of nitrogen by 8 Vol.-%. Because liquid nitrogen (–196°C or –321°F) is frequently used in industry, its evaporation can quickly cause a dangerous oxygen deficiency. Oxygen enrichment (e.g. more than 25 Vol.-%) cannot be perceived by humans, but have severe consequences with respect to the flammability of materials, and may even cause autoignition. This is why explosion protection relates exclusively to atmospheric oxygen concentration. 12| Properties of dangerous gases and vapors At what level does it become dangerous? Oxygen concentration in Vol.-% Less than 17 Oxygen partial pressure in hPa/psi Less than 170/2.5 11 to 14 110 to 140/1.6 to 2.0 8 to 11 80 to 110/1.2 to 2.0 6 to 8 60 to 80/0.9 to 1.2 Less than 6 Less than 60/0.9 Symptoms Early stage of danger due to oxygen deficiency Unnoticed decrease in physical and mental performance Possible sudden loss of consciousness without warning after a certain period of exposure Loss of consciousness within a few minutes – resuscitation possible if performed instantly Immediate loss of consciousness 2.4 Ex, Ox, Tox – gas hazards! Gases and vapors are almost always dangerous. If gases are not present in the atmospheric composition to which we are accustomed and which we can breathe, then safe breathing is threatened. Furthermore, all gases are potentially dangerous in their liquid, compressed, or normal state – the decisive factor is their concentration. There are basically three categories of risk: – Risk of explosion (ex) caused by flammable gases – Oxygen (ox) Risk of suffocation through oxygen deficiency Risk of increased flammability due to oxygen enrichment – Risk of poisoning (tox) by toxic gases Without equipment to assist, mankind is not in a position to detect these risks early enough to enable preventative steps from being taken. And, with a few exceptions, our nose has proven an extremely unreliable warning instrument. For example, hydrogen sulfide can be detected in low concentrations because it smells of rotten eggs. However, the nose can no longer perceive the lethal, high concentrations of hydrogen sulfide. Many fatal accidents have occured because people have fled into what they thought was the safe, odour-free area. | 13 Even harmless gases such as argon, helium or nitrogen can also become dangerous if they are suddenly released, displacing the oxygen that is essential to life. Then there is risk of suffocation. An oxygen concentration of less than six Vol.-% is deadly. An excess of oxygen increases the risk of fire, and can even cause flammable materials to self-ignite. By igniting, flammable gases and vapors can not only cause considerable damage to industrial plants and equipment, they can also threaten people’s lives. Therefore, it is essential to be able to detect Ex, Ox and Tox risks reliably, and to protect human life, industrial plants and equipment, as well as the environment by taking the appropriate measures. Whether Dräger-Tubes® or portable gas detectors, Dräger offers you individual solutions that meet your needs and enable you to counter gas risks professionally. 2.5 Toxic gases and vapors The toxicity of gases and vapors used in industrial processes is defined in laboratory experiments by determining the LC50 rate. On that basis, and together with other scientific tests and experiments relating to occupational health at the workplace, authorized commissions in several countries make recommendations of limit values, which are legally binding. In Germany, this is the Federal Institute for Occupational safety and Health (BAuA). This maximum allowable concentration in the air means that workers will not suffer any detrimental affects to their health if they spend their entire working lives breathing in gas concentrations, which do not exceed that level. This, however, must be assured. Limit value 5,000 ppm 1,000 ppm 500 ppm 200 ppm 100 ppm 50 ppm 20 ppm 10 ppm 5 ppm 1 ppm 500 ppb 200 ppb 100 ppb 50 ppb 10 ppb Selected substances to which this limit value applies carbon dioxide propane, butane acetone methyl ethyl ketone (MEK) butanol n-hexane, toluene acetonitrile chlorobenzene diethylamine 1.1.2.2-tetrachloroethane chlorine methyl chlorformate chlorine dioxide glutaraldehyde methyl isocyanate Status 2010, according to TRGS 900 (Germany) 14| Properties of dangerous gases and vapors T+ Very toxic LC50 < 0.5 g/m3 Arsine, boron trichloride, boron trifluoride, bromine, diborane, fluorine, hydrogen cyanide, hydrogen fluoride, hydrogen phosphide, hydrogen sulfide, nitrogen dioxide, nitrogen monoxide, ozone, phosgene, sulfur tetrafluoride, tungsten hexafluoride T Toxic LC50 = 0.5 ... 2.0 g/m3 Acetonitrile, ammonia, benzene, carbon disulfide, carbon monoxide, chlorine, cyanogen, hydrogen chloride, methanol, methyl bromide, nitrogen trifluoride, sulfur dioxide LC50 (LC stands for “lethal concentration”) is the gas concentration in air, which – when inhaled over a given time period (usually four hours) – kills 50% of experimental animals (normally white laboratory rats). 2.6 Flammable gases and vapors Flammable gases become more dangerous when they have a relatively low LEL (lower explosion limit) or flash point.

The lower explosion limit (LEL) is defined as the concentration of combustion gas (stated in Vol.-%) at which, under standardized conditions, the gas-air mixture can be ignited and will continue to burn on its own accord. The LEL of all known flammable gases and vapors lies in a range of approximately 0.5 to 15 Vol.-%. The LEL of hydrogen in air, for instance, is 4 Vol.-%. Accordingly, a gas sample containing 2 Vol.-% of hydrogen in air can definitely not be ignited. 15.5 Vol% Ammonia 15.0 Vol% 11.0 Vol% Carbon monoxide 10.5 Vol% 10.0 Vol% Formic acid 1.2-Dichloro ethylene Concentration limitation This behavior of gases and vapors has important consequences for practical explosion protection. If a flammable gas cannot be ignited below it's LEL, then we can protect people against explosions by measuring the gas concentrations continuously and using appropriate measures to ensure that concentrations never exceed a level such as half the LEL (50% LEL). This method of preventative explosion protection is often referred to as a primary measure. What is prevented is not the ignition of the gas, but the very formation of an atmosphere which can explode. The preferred method of measuring these concentrations is to use infrared or catalytic bead sensors, which, when used for this purpose, must fulfill certain safety requirements. 9.5 Vol% 9.0 Vol% Methyl bromide 8.5 Vol% 8.0 Vol% 1.1.1-Trichloro ethane Methyl chloride 7.5 Vol% Acetyl chloride 7.0 Vol% Formaldehyde 6.5 Vol% 1.1-Dichloro ethylene 1.2-Dichloro ethane 6.0 Vol% Methanol 5.5 Vol% 1.1-Dichloro ethane Hydrogen cyanide 5.0 Vol% Methyl amine Hydrazine 4.5 Vol% Methane 4.0 Vol% Hydrogen cyanide Vinyl chloride 3.5 Vol% Ethylamine 3.0 Vol% Ethanol Acetonitrile Acrylonitrile Dimethyl ether 2.5 Vol% Ethylene Dimethylformamide 2.0 Vol% i-Propanol Propane ST-1577-2007 1.5 Vol% i-Butane n-Butane n-Butyl acetate 1.0 Vol% 0.5 Vol% n-Hexane n-Octane n-Nonane n-Decane | 17 2.8 Flash point of flammable liquids Although we speak of flammable liquids, in fact, the liquid state is not flammable. It is the vapor, which can form a flammable mixture together with the oxygen in the air. Both the volatility of this vapor and its lower explosion limit (LEL) comprise the measure of its potential danger. This is described by what is known as the flash point. 60 °C Dimethylformamide 50 °C Trimethylbenzene Ethylene glycol 40 °C n-Butanol 30 °C Nonane Chlorobenzene Ethyl benzene 20 °C i-Butyl acetate Ethanol 10 °C Methanol Toluene 0 °C Therefore, the lower the flash point of a flammable liquid, the more dangerous it is. Because the vapor of a flammable liquid is not ignitable below its flash point, preventative explosion protection can consist of using liquids whose flash points are significantly higher than the ambient temperature. This is often done in practice, but it does have the disadvantage – when using such liquids as solvents – that large amounts of energy are required to evaporate them. Gases by definition do not have a flash point, because under normal conditions they do not exist in liquid form. Cyclohexanol Acetonitrile Ethyl acetate – 10 °C Methyl ethyl ketone Cyclohexane – 20 °C n-Hexane Allylamine – 30 °C You cannot ignite diesel (F > 55°C) using a match, but you can ignite gasoline with one (F < –20°C)! ST-1579-2007 To be able to ignite at all, the concentration of vapor above the surface of the liquid must exceed the LEL. Whether it does so or not depends on how much vapor is produced. This, in turn, depends on what is known as the vapor pressure, which depends upon the temperature of the liquid. In safety terms, this is described by defining a flash point (F).The flash point is the temperature at which sufficient vapor forms to create a vapor-air mixture, which can be ignited in a standardized apparatus. If a flammable liquid’s flash point is above 50°C (122° F), then it definitely cannot be ignited at a temperature of 30°C (86° F). 18| Properties of dangerous gases and vapors 2.9 Concentration and their calculation Concentration is defined as the content of a substance within a reference substance. When measuring harmful substances in the air, the quantity of that substance is defined in terms of a concentration in relation to the air. The right units must be chosen to produce useful figures for defining the concentration. High concentration is generally given as Vol.-% – in other words, one part of a substance to 100 parts of air. Air, for example, consists of 21% Vol.-% oxygen, which means that 100 parts of air contain 21 parts of oxygen. Lower concentration levels are measured in ppm = parts per million (mL/m3), or ppb = parts per billion (μL/m3). A concentration of one ppm means there is one part of a substance in one million parts of air (the rough equivalent to one sugar cube inside a gasoline tanker). A concentration of one ppb refers to one part of a substance in one billion parts of air (equivalent to five people out of the entire population of the earth). Converting these very low concentrations into Vol.-% produces the following simple relationship: 1 Vol.-% = 10,000 ppm = 10,000,000 ppb Alongside gaseous components, the air can also contain ‘dissolved’ solid or liquid substances, known as aerosols. The size of droplets or particles borne by the air is very small, which means that measuring them in terms of volume is not very useful. Aerosol concentrations are therefore measured in mg/m3. Vol.-% ppm L/m3 10 1 1 cL/L 3 mL/m ppm = 10–4 μL/L μL/m3 10–7 ppb = nL/L Vol.-% = ppb g/L 104 107 g/L 1 103 mg/L = 10–3 1 mg/m3 = 3 mg/L mg/m 10 L/m3 1 1 cL/L 3 mL/m 10–3 μL/L μL/m3 10–6 nL/L 103 106 1 103 10–3 1 Converting mg/m3 into ppm Molar mass Molar volume c [ppm] = c Molar mass c [mg/m3]= c Molar volume The molar volume of any gas is 24.1 L/mol at 20°C (68° F) and 1,013 hPa (14.7 psi); the molar mass of a specific gas should be adapted dependent on that gas. | 19 3 Introduction to portable instruments In the beginning, there was the canary. These little finches would warn miners about dangerous gases underground: if they stopped singing, the miners had to get out quick. Crude and inaccurate methods of determining gas concentrations in the atmosphere like this one have long been consigned to history. Nowadays, precise measuring instruments monitor the concentration of dangerous gases and flammable vapors. The latest of these are compact, small, robust and flexible single-gas and multi-gas units. Gases and vapors are not always necessarily harmful; after all, the earth’s atmosphere is made of them. It is not until their concentration exceeds critical levels (risk of poisoning and explosion) or drops below certain levels (risk of suffocation through oxygen deficiency) that they can become a threat. This is why portable gas detection devices are used in all kinds of ways throughout many branches of industry. Scenarios range from individual employees and small groups of workers – all the way to large-scale operations such as the industrial shutdown of an entire petrochemical plant. Instruments measuring the various dangerous gases have to perform reliably under changing conditions. This can place great demands on reliability, durability, and flexibility, because in the end the detection equipment is directly responsible for the safety and health of workers. Not every unit may be used in every working environment. Before a device is used, you have to determine whether its specifications are sufficient. These requirements are all laid down in various standards and directives. 3.1 Application areas for portable gas detection Portable gas detection instruments are subject to very diverse requirements. Different application areas require solutions tailored to the measurment task, which also take into account the respective ambient conditions. It is generally possible to distinguish between the following application areas: D-3256-2011 Personal monitoring – These devices are designed to warn the wearer about gas risks in the immediate vicinity. For this reason, they are usually worn on work clothing. The basic requirements that these units therefore have to fulfill are wearing comfort, durability, and reliability. Continuously measuring single-gas and multi-gas instruments are suitable for this kind of work. 20| Portable instruments D-3254-2011 D-16564-2009 Area monitoring – The task here is to monitor an area in which one or more workers are active. The unit is positioned centrally so it can monitor the working area as effectively as possible. The basic requirements in this case are durability, stability, and an alarm, which is extremely easy to perceive (both visually and acoustic). Continuously measuring multi-gas instruments are used in this field. – When several work areas are simultaneously being monitored and these individual areas are not visible from one central point, a wireless alarm chain with several area monitoring devices can provide maximum safety. D-3255-2011 D-16570-2009 Confined space entry – Maintenance and repair work often require people to climb into confined spaces. These areas of work can be especially dangerous because of the lack of space, the lack of ventilation, and the presense or development of hazardous substances. A clearance measurement is required before entry. Multi-gas instruments are used together with corresponding pumps and accessories such as hoses and probes. After a successful measurement where no hazards have been found, the same instruments can be used for continuous personal monitoring while working in the confined space. | 21 D-3257-2011 Leak detection – Leakages can occur wherever gases or liquids are stored or transported. It is important to identify leakages quickly so that the appropriate measures can be taken to avert harm to people, the environment, and the facility. Detection devices combined with corresponding pumps must be able to respond quickly so as to detect small changes in concentration. High 3.2 Requirements for gas detection instruments As safety products, gas detection devices for industrial use must fulfill the statutory requirements (explosion protection, electromagnetic compatibility), as well as other requirements, so that their quality and reliability remains assured even under tough conditions. Explosion protection standards: Design stipulations ensure that the gas measuring instrument does not become a source of ignition itself. Globally accepted standards include CENELEC (ATEX), CSA, UL, GOST, etc. Protection ratings as defined by EN 60529 (IP Code) The IP code provides information about the degree to which a casing provides protection against foreign objects and water. 22| Portable instruments IP = International Protection/Ingress Protection Extract based on DIN EN 60529: D-16408-2009 First Protection against index number solid foreign objects Second Protection against index number water 5 Protection against contact. Protection against interior dust deposits 5 Protection against projected water from any angle 6 Complete protection against touch. Protection against dust penetration 6 Protection against penetrating water during temporary flooding 7 Protection against penetrating water during temporary immersion Protection class IP 67 provides a high degree of robustness, although this can have negative consequences in terms of vapor permeability. The MEWAGG research group (“Mess- und Warngeräte für gefährliche Gase”) – part of BG Chemie (Germany’s statutory employment accident insurance fund for the chemical industry) – therefore advises users who need to detect not only gases like methane and propane, but also higher hydrocarbons and solvents, to check the suitability of equipment with the manufacturer. This can, for example, involve a detection equipment assessment under ATEX. Quality of measurement functions Maintaining a predefined detection quality, even under extreme ambient conditions (temperature, pressure, wind, moisture, vibration, and so on) EN 45 544 – for toxic gases and vapors EN 50 104 – for oxygen EN 60 079-29-1 – for flammable gases and vapors Electromagnetic compatibility as defined by EN 50270 Electrical and electronic devices should not be influenced or interfered with by other electrical, magnetic, or electromagnetic fields – and vice versa. For instance, this means that using a mobile phone or a radio in the immediate vicinity of gas detection devices should not interfere with the instrument’s detection signal, nor should the instrument interfere with the phone. EMC guidelines and standards define means of proving and confirming a device’s insensitivity to interference and low level of interference output. Simply complying with the requirements of a standard or guideline may not be sufficient depending on the various operating and ambient conditions. Rugged industrial applications require much more robust | 23 devices. Dräger pays special attention to these requirements, for example, with an additional in-house "robustness test." RoHS and REACH The requirements for materials and substances used must also be considered during the development and production of gas detection equipment. The European RoHS (Restriction of Hazardous Substances) Directive requires that six particularly dangerous substances may not be contained in electrical and electronic devices. The REACH Regulation (Registration, Evaluation, Authorization, and Restriction of Chemicals) requires that the presence of particularly hazardous materials in products must be disclosed. Dräger seeks to avoid such substances as far as possible within the scope of technical conditions and meets the relevant directives and regulations in this regard. 3.3 Explosion protection Industrial processes very often involve flammable substances, including sometimes flammable particles. In these areas, flammable gases and vapors can sometimes be released on a process-related basis (such as relief valves) or by unforeseen incidents (breakdowns). As a means of prevention, areas such as these are designated EX areas (“zones”) in which only equipment which is reliably protected against ignition may be used. Explosion protection is standardized worldwide; IEC (international), CENELEC (European) and NEC 505 North American standards are similar, and based on the three-zone concept which is rapidly gaining acceptance in the USA. Zone in IEC, NEC 505 and CENELEC Zone 0 Zone 1 Zone 2 Dangerous, explosive atmosphere exists ... constantly, regularly or long-term occasionally rarely and for short periods American explosion protection compliant with NEC 500 is still typically based on the dual division concept: Division in NEC 500 Division 1 Division 2 Dangerous explosive atmosphere exists ... constantly or occasionally rarely and for short periods 24| Portable instruments 3.4 ATEX 137 – directive 1999/92/EC ATEX stands for ATmospheres EXplosibles. This directive has been binding on all systems since July 30, 2006, and is addressed to employers. It describes minimum requirements for the protection of employees’ health and safety in areas at risk of explosion. The directive pursues the following targets: – Prevent the formation of explosive atmospheres; if this is not possible – Prevent the ignition of explosive atmospheres; if this is not possible – Reduce the harmful effects of an explosion to a tolerable minimum. Employers are obliged to assess the risk of explosion in the relevant areas. Zone categories are defined by answering the question: how likely is it that an explosive atmosphere (gas, vapor, dust) will form in the areas concerned? ZONE DEFINITIONS IN ATEX 137, ANNEX I, 2 Areas at risk of explosion are divided into the following zones according to the likelihood of an explosive atmosphere forming there: Zone 0 Area in which explosive atmospheres comprising mixtures of air and flammable gases, vapors, and aerosols are present constantly, frequently, or over long periods of time. Zone 1 Area in which, under normal operation, an explosive atmosphere can occasionally form as a mixture of air and flammable gases, vapors, or aerosols. Zone 2 Area in which, under normal operation, an explosive atmosphere consisting of a mixture of air and flammable gases, vapors, or aerosols normally does not form – or, if so, only briefly. Zone 20 Area in which explosive atmospheres in the form of clouds of combustible dust in the air are present constantly, frequently, or over long periods of time. Zone 21 Area in which, under normal operation, an explosive atmosphere can occasionally form as clouds of combustible dust in the air. Zone 22 Area in which, under normal operation, an explosive atmosphere in the form of a cloud of combustible dust in the air normally does not form – or, if so, only briefly. | 25 Depending on the zone identified, only certain gas measuring instruments may be used there (this table links the categories of ATEX 95 with the zones in ATEX 137): Permitted use Instruments in category 1 Instruments in category 2 Instruments in category 3 Gas, vapor (G) Zone 0, 1, 2 Zone 1, 2 Zone 2 Dust (D) Zone 20, 21, 22 Zone 21, 22 Zone 22 (For instrument categories, see section 3.5 ATEX 95) The instrument group and temperature category requirements are then determined by defining the flammable gases, vapors, aerosols, and dusts used, along with their ignition temperatures.

It describes the requirements that must be fulfilled by gas detection devices used in areas at risk of explosion, and which incorporate their own potential ignition sources. The CE symbol of conformity – coupled with information about the equipment category (described the zones of the area at risk of explosion in which the gas warning instrument may be used as an electrical device) may look like this: Markings as defined by 94/9/EC (ATEX 95) 0158 Notified body concerning quality control of production Conforms with EU requirements Markings (as defined by ATEX): I M2 / II 2G Category I: Mining Type of explosive atmosphere: G: gas, vapor, aerosol; D: dust II: Industry Complies with directive 94/9/EC Equipment groups I and II indicate in which area the device may be used: I = Mining II = Industry Information then follows about which equipment category the gas detection device satisfies: Category 1 Category 2 Category 3 Very high level of safety, sufficient safety provided by two protective measures or in the event of two faults Sufficient safety in the event of frequent equipment faults or one breakdown Sufficient safety if operation is fault-free Finally, the atmosphere is indicated (G: gas, vapor, aerosol or D: conductive and non-conductive combustible dusts). | 27 The designation indicates the zones in which the instrument may be used (example for industry).

In addition to the requirements, markings are defined as well. A marking according to ATEX as well as a marking to indicate the equipment protection level (EPL = Equipment Protection Level) is required. With the introduction of the EPL, it is now possible to allocate which device may be used in which explosive atmosphere or area outside of Europe as well. 28| Portable instruments Ignition protection types provide information about the protective measures incorporated into a device: Ignition protection types and CENELEC standards Abbreviation CENELEC standard Ignition protection type EN 60079-0 EN 60079-6 EN 60079-2 EN 60079-18 EN 60079-5 EN 60079-1 Gas Ex e Ex ia Ex ib Ec ic EN 60079-7 EN 60079-11 Ex n Dust EN 60079-15 General terms Oil immersion Pressurized encapsulation Encapsulation Powder / Sand filling Explosion/Flame-proof encapsulation Increased safety Intrinsic safety ia required for Zone 0 ib sufficient for Zone 1 ic sufficient for Zone 2 Ignition protection types for Zone 2 EN 61241-0 EN 61241-1 EN 61241-2 EN 61241-11 General terms Protection by instrument housing Dust – pressurized encapsulation Dust – intrinsic safety Ex o Ex p Ex m Ex q Ex d Ex tD Ex pD Ex iD Comparison: Designation according to IEC (2007) / CENELEC (2009) and EU directive 94/9/EG (ATEX) EPL (Equipment Protection Level) according to according IEC / CENELEC to EU directive 94/9/EG Ma Mb Ga Gb Gc Da Db Dc M1 M2 1G 2G 3G 1D 2D 3D Area Mining explosive gas atmosheres area with combustible dust Explosion group Explosion group I encompasses equipment used for mining (coal dust and methane atmospheres). Explosion group II applies to all other areas (all other gases). For the ignition types “explosion/flame-proof encapsulation” and “intrinsic safety,” explosion group II is subdivided into IIA, IIB, and IIC. This subdivision relates to the different levels of ignitability in terms of ignition penetration and electrical sparks. Explosion group IIC covers all gases and vapors. In the future, we will also see explosion group III for flammable dusts, and this in turn will be subdivided in three other groups (IIIA: flammable fibers, IIIB: non-conductive dust, IIIC: conductive dust). | 29 CATEGORIZATION OF GASES AND VAPORS Explosion group Ignition temp.

The ignition temperature of the gas must be greater than the maximum surface temperature. T6 covers all gases and vapors. For dust explosion protection, the maximum surface temperature is specified in °C, e.g. T130 °C (266 °F).

There are a number of third party approval agencies in the US – UL, FM, ETL and many others. They all provide ratings for Intrinsic Safety and provide some performance testing. They do not have any regulatory or legal status. They are primarily a certification to verify the safety of a product for insurance purposes and to minimize liability. Underwriters Laboratories Inc. (UL) is a private third party product safety certification organization. UL develops standards and test procedures for products, materials, components, assemblies, tools and equipment, chiefly dealing with product safety. UL is one of several companies approved for such testing by the U.S. federal agency OSHA. OSHA maintains a list of approved NRTL's. UL develops standards for safety, often based on American National Standards (ANSI) and evaluates many types of products. A typical standard for electronic products includes not only requirements for electrical safety, but also spread of fire and mechanical hazards. UL evaluates products for compliance with specific safety requirements. UL develops its Standards to correlate with the requirements of model installation codes, such as the National Electrical Code (NEC). UL evaluates instruments for Intrinsic Safety (IS) for use in hazardous areas. The IS rating means that the instrument will not be the source of ignition in a potentially explosive environment. The areas are defined by the type of hazard that may exist (Class), the possibility of a hazard being present in the area (Division) and the specific hazards that may be encountered (Group). UL 913 is the applicable Standard for Safety for Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classified) Locations. | 31 Hazardous Location: An area where the possibility of explosion and fire is created by the presence of flammable gases, vapors, dusts, fibers or filings. Class I Class II Class III Division 1 Division 2 Those areas in which flammable gases or vapors may be present in the air in sufficient quantities to be explosive or ignitable. Those areas made hazardous by the presence of combustible dust. Those areas in which there are easily ignitable fibers or filings present, due to type of material being handled, stored or processed. Division 1 is the normal situation; the hazard would be expected to be present in everyday production operations or during frequent repair and maintenance activity. Division 2 is the abnormal situation; material is expected to be confined within closed containers or closed systems and will be present only through accidental rupture, breakage or unusual faulty operation. Groups The gases and vapors of Class I locations are broken into four groups by the codes A, B, C and D. These materials are grouped according to the ignition temperature of the substance, its explosion pressure and other flammable characteristics. Class II – dust locations – groups E, F & G. These groups are classified according to the ignition temperature and the conductivity of the hazardous substance. The gases and vapors of Class I locations are broken into four groups by the codes A, B, C and D. These materials are grouped according to the ignition temperature of the substance, its explosion pressure and other flammable characteristics. Group A Acetylene Group B Hydrogen Group C Ethyl-Ether, Ethylene, Cycle Propane Group D Gasoline, Hexane, Naptha, Benzene, Butane, Propane, Alcohol, Laquer Solvent Vapors, Natural Gas Class II – dust locations – groups E, F & G.

Division 1: Where ignitable concentrations of flammable gases, vapors or liquids can exist all of the time or some of the time under normal operating conditions. Division 2: Where ignitable concentrations of flammable gases, vapors or liquids are not likely to exist under normal operation conditions. Zone 0: Where ignitable concentrations of flammable gases, vapors or liquids are present continuously or for long periods of time under normal operating conditions. Zone 1: Where ignitable concentrations of flammable gases, vapors or liquids are likely to exist under normal operation conditions. Zone 2: Where ignitable concentrations of flammable gases, vapors or liquids are not likely to exist under normal operation conditions. US Mine Safety Health Administration (MSHA) In the United States, equipment for use in mines must be approved by the US Mine Safety Health Administration (MSHA). MSHA maintains its own test facilities and has specific standards for electrical equipment being used in mines. MSHA defines and enforces safety regulations for all types of mining operations as legislated by the US Congress. This includes both underground and above ground coal mines, metal/nonmetal mines and large tunneling operations. The MSHA approval process is a legal requirement for use of equipment in a mine. MSHA considers all underground operations as hazardous locations. An MSHA approval reads a bit differently than a UL approval label, although the same classification codes are used: Permissible Gas Monitor Only as to intrinsic safety for use in hazardous locations, Class I Div. 1, Group A 90 dB in 30 cm (1 ft.) yes Replaceable lithium battery 40| Portable instruments Dräger Pac 3500/5500/7000 FEATURES COMPARISON Compatible sensors: XXS EC sensors Operation time Data logger: Battery life CO, H2S Battery life O2 Bump test Approvals: ATEX Measurement performance certificate UL CSA IECEx GOST RUS – Pattern Approval Certificate of measuring instruments MED CE mark Dräger Pac 3500 Dräger Pac 5500 O2, CO, H2S-LC O2, CO, H2S-LC ATEX I M1 / II 1G Ex ia I/IIC T4 – ATEX I M1 / II 1G Ex ia I/IIC T4 – Dräger Pac 7000 O2, CO, H2S-LC, CO2, CI2, HCN, NH3, NO, NO2, PH3, SO2, H2S, OV; OV-A 2 years Unlimited Unlimited Events saved with Events saved with Concentrations and date and time (up to date and time (up to events saved together 60 events) 60 events) with date and time (up to 120 hours at 1 data set per minute). 8 hours/day, 2 years 8 hours/day, 2 years 24 hours/day (1 minute alarm per day) (1 minute alarm per day) > 5,500 hours (1 minute alarm per day) 8 hours/day, 1 year 8 hours/day, 1 year 24 hours/day (1 minute alarm per day) (1 minute alarm per day) > 2,700 hours (1 minute alarm per day) Pushing the OKPushing the OKAutomatic button 3 times button 3 times ATEX I M1 / II 1G Ex ia I/IIC T4 XXS EC Sensoren: O2, H2S, CO Class I, II Div. 1 Group Class I, II Div. 1 Group Class I, II Div. 1 Group A, B, C, D, E, F, G A, B, C, D, E, F, G A, B, C, D, E, F, G Temp.

The sensor is crucial in determining the quality of measurements, and therefore it has a fundamental influence on the safety of the user. The development and production of sensors is part of Dräger’s core competence. | 67 4.1 Selecting the proper measurement method Selecting the correct measuring principle is essential when detecting dangerous gases. Every measuring principle has its own strengths and limits, and each is better for particular groups of gases (flammable/toxic gases and oxygen). For this reason, it is important to ask which gases/vapors occur in the workplace Generally speaking, we differentiate between the following gas risks: Risk of explosion – Wherever flammable gases and vapors occur, there is an increased risk of explosion. Typical areas for this include mining, refineries, the chemical industry, and many others. Infrared and catalytic bead sensors are used to detect this type of risk. These sensors usually detect gas concentrations in the LEL (lower explosure level) range, but some of them can also be used for the 100 Vol.-% range. Lack or excess of oxygen – A lack of oxygen is life-threatening. An excess of oxygen can affect the flammability of materials and can even cause auto-ignition. Electrochemical sensors are used to measure oxygen. Their measuring range is from between 0 and 25 Vol.-% all the way up to 100 Vol.-%. Toxicity – Poisonous substances can occur anywhere – in industrial production and processing, in transport (rail, road, ship), in the case of incomplete combustion (CO), and also as a result of completely naturally processes such as rotting and decomposition of biomass. Electrochemical and PID sensors are used to detect toxic gases. The decision about which sensor type is the right one for a particular application also depends on other factors such as: – What other hazardous material are present (cross-sensitivity)? – Is it necessary to measure hazardous material selectively, or is it more sensible to measure a complete parameter? 64-19-7 108-24-7 67-64-1 98-86-2 107-02-8 107-13-1 107-05-1 107-18-6 7785-26-4 7664-41-7 62-53-3 Acetic acid Acetic anhydride Acetone Acetophenone Acrolein Acrylonitrile Allyl chloride Allylalcohol Alpha-pinene Ammonia Aniline data known Sensitivity not yet determined 75-07-0 Acetaldehyde  Sensitivity CAS NO.

Typically, this is achieved through the use of special and suitably heated catalyst material, which slightly increases its temperature through the resulting heat of reaction. This slight increase in temperature is a measure of the gas concentration. | 87 A small platinum coil is embedded in a porous ceramic bead with a diameter of less than 1 mm (0.04 in.). A current flows through the platinum coil, heating the pellistor to several hundred degrees. If the pellistor contains a suitable catalytic material, then its temperature will increase in the presence of flammable gases, which in turn causes the resistance of the platinum coil to increase. This change in resistance can then be evaluated electronically. The oxygen required for the combustion comes from the ambient air. This sensor works on the basis of the catalytic bead principle. D-16400-2009 Catalytic bead sensors Methane-Molecule H²O-Molecule CO²-Molecule O²-Molecule Flame arrestor Gas Detector element Compensator element Reaction In order to eliminate changes in the ambient temperature, a second pellistor is used with almost the same structure, but which does not react to gas (it may, for example, contain no catalytic material). Coupled by a Wheatstone bridge, the two pellistors then form a sensor circuit, which is largely independent of the ambient temperature, and which can detect the presence of flammable gases and vapors. Because a catalytic bead sensor contains hot pellistors, it can – if the lower exposure level (LEL) is exceeded – become a source of ignition in its own right. This is prevented using a metal sinter disk. If an ignition occurs in the interior of the catalytic bead sensor, then the sensor's housing withstands the explosion pressure and the flame is cooled to below the ignition temperature of the gas by the sinter disk. This ensures that the flame does not penetrate through to the outside of the sensor. If gas concentrations are far above the LEL (above the stoichiometric mixture ratio), then the detector’s sensitivity drops, because the ambient oxygen required for combustion is displaced. This can lead to ambient measurement results. That is why, in Dräger Cat Ex sensors, a compensatory element measures the thermal conduction of the ambient air being monitored, and this differs from the thermal conduction of normal air if a series of gases are present. The variable thus obtained then allows the device to provide a clear reading for the LEL range.

DETECTING OTHER GASES AND VAPORS Through the use of cross sensitivities for the measurement range of 0 to 100% LEL. The correction factors given are typical readings when calibrated with methane (CH4) and apply to new sensors without sensor filters. A LEL of 5.0 Vol.-% was used for methane. If a LEL of 4.4 Vol.-% is used, then the figures in the table must be multiplied by a factor of 1.14. The correction factors listed were determined for 25 °C (77 °F) and may fluctuate by ± 30% (source: NIOSH, Pocket guide to chemical hazards, 1997). The table does not claim to be complete. Calibrating the sensor using the actual gas that is to be measured is always preferable. The sensor may also be sensitive to other gases and vapors.

In a container containing gaseous hydrocarbons such as methane or propane, the intensity of an incoming infrared light will be weakened, and the degree of this weakening is dependent on the concentration of gas. Air: infrared light passes through without weakening – intensity remains the same Gas (e.g. methane): infrared light becomes weaker as it passes through – intensity drops in relation to the concentration of methane. This is the principle of an infrared measuring instrument that utilizes Dräger IR sensors. Flammable gases and vapors are mostly hydrocarbons, and hydrocarbons are almost always detectable by means of their typical IR absorption levels. Functional principle: the ambient air to be monitored passes into the measuring cuvette by means of diffusion or through the use of a pump. The infrared transmitter produces broad-band radiation that passes through a window into the cuvette, where it is reflected off the mirrored walls and passes through another window, falling onto the double detector. This double detector consists of a measurement and a reference detector. If the gas mixture contains a percentage of hydrocarbons, then some of the radiation is absorbed and the measurement detector produces a reduced electrical signal. The signal from the reference detector remains unchanged. Fluctuations in the performance of the infrared transmitter, dirt on the mirror and windows, and interference from dust or aerosols in the ambient air have the same effect on both sensors, and are fully compensated. 110| Dräger infrared sensors DrägerSensor® Smart IR Ex Used in Dräger X-am 7000 Plug & Play yes Replaceable yes Order no. 68 10 460 Guaranty 5 years Selective filter – MARKET SEGMENTS Telecommunications, shipping, sewage, gas supply companies, refineries, chemical industry, mining, landfills, biogas plants, tunneling.

For this reason, personal protection in the workplace ideally includes the additional measurement of ppm levels of volatile organic substances using a PID sensor. | 129 The air is drawn into the measuring chamber through the gas inlet. In the chamber, a UV lamp produces photons, which ionize certain molecules within the flow of gas. A relatively high amount of energy is required to ionize the air’s permanent gases such as noble gases, nitrogen, oxygen, carbon dioxide, and water vapor. For this reason, these gases do not interfere with the measurement of the harmful substances. Most of the organic substances recognized as dangerous (such as hydrocarbons) are ionized and subjected to the electrical field between the electrodes in the measuring chamber. The strength of the resulting current is directly proportional to the concentration of ionized molecules inside the chamber. This makes it possible to determine the concentration of harmful substance in the air.

Ionization energy is something specific to each material, like the boiling point and vapor pressure. For a substance to be ionized, its ionization energy must be lower than the photon energy from the lamp used in the PID. Two types of lamps are commonly used – the 10.6-eV lamp and the 11.7-eV lamp. This enables a PID to detect whole groups of harmful substances, while it can also be used to measure single substances if calibrated accordingly. Calibration and response factors Isobutylene is used to calibrate a PID, unless the actual substance being measured can be used. The relative sensitivity to other substances is then expressed in terms of response factors. If a substance is detected with greater sensitivity than isobutylene, then its response factor is less than one. Substances that are detected with less sensitivity than isobutylene have a response factor greater than one.

An electrochemical sensor is a micro-reactor, which produces a very small but measurable current when reactive gases are present. As in a normal household battery, this involves an electrochemical process, since the chemical transformation produces electrons. | 133 The basic principle behind an electrochemical sensor involves at least two electrodes (a measuring electrode and a counter-electrode), which have contact with each other in two ways: first, through an electrically conductive medium (electrolyte, meaning a fluid that conducts ions) and, second, through an external electrical circuit (electron conductor). The electrodes are made of a special material that also has catalytic characteristics so that certain chemical reactions take place at what is known as the three-phase zone where gas, solid catalyzer, and liquid electrolyte meet. A dual-electrode sensor (measuring and counterelectrode) does, however, have many drawbacks. For instance, if high concentrations of gas occur, this leads to higher currents in the sensor and, therefore, to a drop in voltage. The drop in voltage, in turn, changes the preset sensor voltage. This can lead to unusable readings or, in the worst case, it can cause the chemical reaction inside the sensor to come to a halt during the measurement process. For this reason, the Dräger XS and XXS sensors contain a third electrode known as the reference electrode, which does not have a current passing through it, and whose potential therefore remains constant. It continuously measures the sensor voltage at the measuring electrode, which can be corrected using the sensor’s control enhancement. This produces a considerably improved measuring quality (e.g. in terms of linearity and selectivity) and a longer life time.

This memory module contains all of the sensor’s relevant data, which, when plugged into Dräger X-am 7000 is retrieved. The device then automatically adjusts itself to these figures (e.g. calibration figures, alarm level). This "plug & play" function enables sensors to be swapped between devices without performing operations such as a re-calibration. XXS sensors are used in the following devices: Dräger Pac 3500 to 7000 and Dräger X-am 1700/2000/5000 and to 5600. In this case, the sensor-relevant data is stored in the device. When a sensor is changed, this information is transferred using a software application. 134| DrägerSensor® XS CONTENTS XS SENSORS XS Sensors XS EC Amine XS EC Cl2 XS EC ClO2 XS EC CO XS 2 CO XS R CO XS CO micro Pac XS EC CO HC XS EC CO2 XS EC COCl2 XS EC H2 XS EC H2 HC XS EC HCN XS EC HF/HCl XS EC H2S 100 XS 2 H2S XS R H2S XS H2S microPac XS EC H2S HC XS EC 2 H2S SR XS EC H2O2 XS EC Hydrazine XS EC Hydrazine D XS EC Hydride XS EC NH3 XS EC NO XS EC NO2 XS EC Odorant XS EC OV XS EC OV-A Chemical name (synonym) amine like methylamíne, ethylamine, dimethylamine etc. chlorine chlorine dioxide carbon monoxide carbon monoxide carbon monoxide carbon monoxide carbon monoxide carbon dioxide phosgene hydrogen hydrogen hydrogen cyanide hydrogen chloride / hydrogen fluoride hydrogen sulfide hydrogen sulfide hydrogen sulfide hydrogen sulfide hydrogen sulfide hydrogen sulfide hydrogen peroxide hydrazine hydrazine hydride like hydrogen phosphide, phosphine, arsine etc. ammonia nitrogen monoxide nitrogen dioxide sulfur compounds like tetrahydrothiophene, methylmercapten, ethylmercaptan etc. organic gases and vapors like ethylene oxide, ethene, propene etc. organic gases and vapors like ethylene oxide, styrene isobutylene etc. 136 138 140 142 142 142 142 148 150 152 154 156 158 160 162 162 162 162 168 170 172 174 176 178 180 182 184 186 188 190 | 135 CONTENTS XS SENSORS XS Sensors XS EC O2-LS XS 2 O2 XS R O2 XS O2 microPac XS EC O2 100 XS EC PH3 HC XS EC SO2 XS EC THT Chemical name (synonym) oxygen oxygen oxygen oxygen oxygen hydrogen phosphide, phosphine sulfur dioxide tetrahydrothiophene 192 192 192 192 196 198 200 202 136| DrägerSensor® XS DrägerSensor® XS EC Amine Used in Dräger X-am 7000 Plug & Play yes Replaceable yes Guaranty 1 year Order no. 68 09 545 Selective filter – MARKET SEGMENTS Foundries, refineries, power plants TECHNICAL SPECIFICATIONS Detection limit: Resolution: Measurement range: Response time: Measurement accuracy Zero point: Sensitivity: Long-term drift, at 20°C (68°F) Zero point: Sensitivity: Warm-up time: Ambient conditions Temperature: Humidity: Pressure: Influence of temperature Zero point: Sensitivity: Influence of humidity Zero point: Sensitivity: Test gas: 2 ppm 1 ppm 0 to 100 ppm CH3NH2 (methylamine) 0 to 100 ppm (CH3)2NH (dimethylamine) 0 to 100 ppm (CH3)3N (trimethylamine) 0 to 100 ppm C2H5NH2 (ethylamine) 0 to 100 ppm (C2H5)2NH (diethylamine) 0 to 100 ppm (C2H5)3N (triethylamine) ≤ 30 seconds at 20 °C or 68 °F (T50) ≤ ± 2 ppm ≤ ± 3% of measured value ≤ ± 2 ppm/month ≤ ± 3% of measured value/month ≤ 12 hours (–40 to 50)°C (–40 to 122)°F (10 to 90)% RH (700 to 1,300) hPa ≤ ± 5 ppm ≤ ± 5% of measured value ≤ ± 0.1 ppm/% RH ≤ ± 0.2% of measured value/% RH approx. 50 to 100 ppm NH3 or one of the other target gases (MA, DMA, TMA, EA, DEA, TEA) | 137 SPECIAL CHARACTERISTICS Six different amines can be detected using this sensor.

The Dräger Sensor XS EC H2O2 has a defined cross sensitivity to sulphur dioxide (SO2). Alternatively, the sensor can be calibrated using SO2. Such surrogate calibration with SO2 can lead to an additional measuring error of up to 20%. We recommend calibrating devices using the gas that is to be detected during actual operation. This method of target gas calibration is more accurate than calibrating with a surrogate gas. | 173 SPECIAL CHARACTERISTICS This sensor is used in the Dräger X-am 5100 to monitor the H2O2 (hydrogen peroxide) concentration in the ambient air.

Hydrogen affects the CO signal in conventional sensors, which leads to many false alarms. The DrägerSensor® XXS CO H2-CP uses two measuring electrodes – one of which measures CO and H2, the other only H2. The CO level is calculated and displayed on the basis of the difference between the two signals. A hydrogen concentration of 1,000 ppm (2.5% LEL) causes a maximum displayed concentration of only 15 ppm CO, which does not activate the CO alarm.

Example: At a detection limit of 2 ppm, the value 2 ppm is depicted in the display as the first concentration. Concentrations lower than 2 ppm are depicted as 0 ppm. Indicates the concentration increments of the display. For example: With a detection limit of 2 ppm and a resolution of 1 ppm, the concentrations are depicted in the following increments: 2 ppm / 3 ppm / 4 ppm … Indicates the maximum measuring ranges of the sensors. All gases/ vapors with their ranges are indicated if a sensor can be used for different gases and vapors. Typically, the times listed here are T50 or T90 at 20°C (68°F). These times indicate when 50 % or 90 % of the final signal has been reached. The data presented here relate to the zero point and the sensitivity: A zero point measuring accuracy of ≤ ± 2 ppm means the zero point may fluctuate between - 2 ppm and + 2 ppm. For example, if a measuring accuracy of ≤ ± 3 ppm of the measured value is indicated for the sensitivity, then the following can be said about the measuring accuracy: The concentration is between 97 and 103 ppm if 100 ppm is displayed. This information indicates the typical drift of the sensor in the zero point and in the sensitivity across a longer period. This data may refer to a month or a year. The long-term drift data of ≤ ± 0.2 ppm/year at 20° C (68°F) states that this sensor drifts max. ≤ ±2 ppm per year. A value for the long-term drift of the sensitivity of ≤ ± 2 ppm/month, indicates that after two months with a display of 100 ppm, the maximum gas concentration may be between 96 and 104 ppm. The warm-up time indicates the amount of time needed before a newly installed sensor or a sensor, which was without electricity for a period of time and then is powered up again, can be calibrated. However, the sensor may be ready for use after only a few minutes. In this case, there may be a higher rate of measurement errors. Indicates the temperature, humidity, and pressure range in which the sensor may be used. The indicated corrections do not apply with measurements outside of the permissible ambient conditions.

The addresses are listed on the rear cover page of this manual. 270| Influence of temperature: Influence of humidity: Test gas: The effect temperature may have must be considered when the measurement temperature deviates from the temperature during the calibration. Example 1: Temperature effect on the sensitivity amounts to ≤ ± 5 % of the measured value. This means that the max. deviation across the entire temperature range of the sensor (typically - 40 to 50°C or - 40 to 122°F) is expected to be ≤ ± 5 %. At an ambient temperature of, for example, - 10° C (14°F) and a displayed value of 100 ppm, the max. gas concentration may be between 95 and 105 ppm. The temperature difference between the temperature of the measurement and the temperature of the calibration must be taken into account with some sensors. Example 2: The effect of temperature on the sensitivity is ≤ ± 0.5 % of the measured value / K. The sensor was calibrated at 25°C (77°F), the measurement is taken at an ambient temperature of 35°C (95°F). The temperature difference is then 10°C (14°F) or 10 K. This yields the following calculation: 10 x 0.5% = 5% With an ambient temperature of 35°C (95°F) and a displayed value of 100 ppm, the max. gas concentration is between 95 and 105 ppm. The effects of humidity must be considered if the humidity during measurement deviates from the calibration humidity. Example 1: The effect of humidity on the sensitivity is ≤ ± 0.5 % of the measured value. This means that the max. deviation to be expected amounts to ≤ ± 5% with the deviation applying to the entire humidity range of the sensor (typically 10 to 90 % rel. humidity). With an ambient humidity of 50 %, for example, and a displayed value of 100 ppm, the max. gas concentration may be between 95 and 105 ppm. The humidity difference between the humidity of the measurement and the humidity of the calibration must be taken into account with some sensors. Example 2: The effects of humidity on the sensitivity is ≤ ± 0.02 % of the measured value / % rel. humidity. The sensor was calibrated at 0% rel. humidity, the measurement is taken at an ambient rel. humidity of 50 %. The difference of the rel. humidity is then 50 %. This yields the following calculation: 50 x 0.02 % = 1 % With an ambient humidity of 50 % and a displayed value of 100 ppm, the max. gas concentration is between 99 and 101 ppm. Recommended test gas concentration for calibrating the sensor. | 271 272| Accessories ST-10238-2007 5 Accessories | 273 5.1 Introduction The following chapter provides information about how to choose the right accessories and how to use them properly. Safety Detection devices that do not work correctly can provide no protection and can lead to accidents. The only way to guaranty a reliable and correct measurement and warning of gas risks is to test your detection device using a known gas concentration. This is commonly referred to as a function or bump test. The device may need to be calibrated. Additional features You can extend the functionality of gas detection devices by using the right accessories. For instance, a device for personal monitoring can be turned into a device for detecting leaks and for performing clearance measurements when entering confined spaces, simply by using a pump, probe, and extension hose. The right materials are important – for example, when using extension hoses. Configuration/documentation/archiving Gas detection devices can be adapted to a variety of applications by adjusting them to different evaluation parameters using an additional software program. This software runs on a separate computer. In many places of work, the exposure to hazardous material must be evaluated and documented. This process should be quick and intuitive. 5.2 Equipment for calibration and function tests Gas detection devices are used for continuous measurements. Environmental influences or other gases can change the calibration, with which the sensor is delivered to the customer. Testing an instrument using a known gas concentration (also known as a function or bump test) is the only way to guarantee reliable and correct measurement of and warning against gas hazards. This test is important to verify whether the gas to be measured can flow through the dust and water filter to the sensor, to check that the sensor is properly calibrated, and to test that alarms are working and are set correctly. If the gas detector has been in contact with very high concentrations of toxic gases or vapours, it must immediately undergo a function (bump) test and the necessary adjustments, regardless of the required function test interval. The various institutions stipulate regular sensitivity checks and functional tests (bump tests) for gas detection devices; In Germany, BG Chemie therefore recommends regular checks / calibrations in its data sheets T021 (gas warning equipment for toxic gases/vapors) / T023 (gas warning equipment for explosion protection). The EN 60079-29-2 standard (Gas detection devices – selection, installation, application, and maintenance of equipment for 274| Accessories the measurement of flammable gases and oxygen), which applies to all the member states of the European Union also stipulates a sensitivity test immediately before use (international: IEC 60079-29-2). ST-5002-2005 5.3 Basic test with gas The easiest and least expensive way to test the function of your portable gas detection instrument is to conduct a basic test with gas. All you need is a test gas bottle containing the respective test gas, a trigger regulator and aninstrument-specific calibration adapter. The instrument's alarm is triggered by briefly exposing the sensors to the test gas. To adjust the instrument via a PC, you need additionally the Dräger CC-Vision software, which allows individual configuration and calibration of your gas detection instruments. 5.4 Dräger Bump Test Station The Dräger Bump Test Station was designed to allow a function (bump) test to be performed with a test gas in order to check the warning functions of gas detection instruments. An integrated instrument-specific adapter is provided to test the Dräger Pac 3500 to 7000, and of Dräger X-am 1/2/5500 5600/, 3000 and 7000. When the concentration shown on the instrument's display is within an acceptable tolerance to the concentration of the test gas and the alarms were trigged, the function (bump) test was successful and verifies the instrument calibration. If the function (bump) test was not successful, the instrument needs to be calibrated. With some devices, this is done automatically following an unsuccessful function test in the Dräger Bump Test Station. Instruments with an event or data logger will store the results (pass or fail) of the function (bump) test, as well as the subsequent automatic calibration when applicable. The Dräger Bump Test Station functions independently, without any external power supply, making it ideal for use anywhere in the field. The data from the Dräger Bump Test Station can be sent to a Dräger mobile printer ST-4700-2005 | 275 using an optical port. This printer stores the results of the function test and prints them out. The results can also be exported using the Dräger CC-Vision software. The tests are very short – sometimes only ten seconds, because the sensors respond so quickly – which makes for very low gas consumption and reduced operating costs. 5.5 Dräger E-Cal – the workshop solution The Dräger E-Cal automatic testing and calibrating station incorporates as many as ten different instrument modules. Because Dräger detection devices can be calibrated and adjusted simultaneously, they are quick and therefore economic to maintain. The Dräger E-Cal is modular in design and, when fully equipped, can consist of a computer, a master station, and as many as ten different device modules. Master station The Master Station allows you to use either two, six or twelve different gases, and supports up to ten instrument modules. Device module When a Dräger portable gas detection instrument is inserted into its module, the sensors contained within are automatically detected. Once calibration has been successfully completed, the results are shown on both the module and the PC. Additionally, you can use the instrument module, with the respective plug, to charge your equipment. With the help of an optional adapter and a computer, each device module can also be operated independently of the master station, and used as an economic alternative for simple testing of a device’s functionality. Dräger CC-Vision software The Dräger CC-Vision E-Cal software features intuitive operation and the configurable GO button makes the instrument even easier to use. Specific workshop processes i.e. function (bump) test, calibration, download of data logger or battery test are carried out automatically and simultaneously for up to 10 instruments. Combined with a search function, the software also offers equipment management. The Dräger CC-Vision E-Cal software provides a wide range of different analysis and tracking functions, e.g. who a particular instrument belongs to, 276| Accessories ST-591-2005 which instruments require calibration and when, and what the calibration history is for individual instruments. The software additionally prints out a record to facilitate your data documentation. The workshop solution also simplifies configuration of several Dräger portable gas detection instruments. The Dräger CC-Vision E-Cal software is compatible with any PC. Purge module An optional Purge Module is also available. When there is no ventialation systemminstalled this special option ensures the active and defined suction of waste gases – some of which are toxic and explosive – out of the Dräger E-Cal Station.

Dräger test and calibration gases are produced in accordance with ISO 9002, which guarantys a high standard of quality worldwide. They are available as single gases as well as gas mixtures. The gases are packaged in small, convenient disposable cylinders, which can be taken anywhere, thus enabling on-site function testing with the Dräger Bump Test Station. Another advantage of the disposable cylinders is the fact that they do not need to be returned – once empty, you can simply dispose of them in an environmentally-friendly manner such as with metal waste. This means no rental or transport costs to return the cylinders. | 277 5.7 Regulator valves All of the regulator valves we supply are suitable for our test and calibration gas cylinders, and permit flow rates of 0.5 l/min. USE ST-4806-2005 For devices without internal pumps This valve has a thumb wheel for manually opening and closing the gas outlet. Model 715 ST-4804-2005 For devices with internal pumps This valve opens automatically when the pump draws in gas. On-demand regulator valve For the Dräger E-Cal station This regulator valve can be used in conjunction with devices that have internal pumps. If large, refillable cylinders with DIN 14 connectors are being used for the E-Cal station, then this valve can also be used in conjunction with a DIN 14 adaptor, which is also available from Dräger. ST-4809-2005 For quick function tests prior to using a device Pulling the trigger manually applies calibration gas briefly to the gas detection device’s sensor. Tipping the trigger upwards fixes the regulating valve in the open position, providing a continuous flow of gas. Trigger-regulator valve 278| Accessories ST-4983-2005 5.8 Pumps ST-4990-2005 Dräger X-am 3000 with pump adapter The Dräger X-am 1700/2000/5000/5600 devices can be also have this pump function through the use of the external X-am 1/2/5000 pump. When the detection device is put in to place, the pump function starts automatically and a flow test is initiated. Once the flow test is complete, the pump is ready for use and can be used in conjunction with a hose with a length of 20 meters (66 ft.). The flow test prior to every use ensures safe and reliable pump operation. If the pump flow becomes too low, then a flow alarm is displayed on the pump. An easily replaceable dust and water filter protects the pump and the sensors in the device against dirt and contamination. ST-9477-2007 Dräger X-am 7000 with pump adapter Dräger X-am 3000 and Dräger X-am 7000 are optionally available with an integrated high-performance pump. When you attach the pump adaptor, the device automatically switches from diffusion to pump mode. This accessory enables the device to draw gas from remote measuring sites through a 20-meter-long (66 ft.) hose or, with a Dräger X-am 7000, a 45-meter-long (or 148 ft.) hose, thus enabling clearance measurements in shafts, tanks, and so on. The pump in the device is continuously monitored electronically. If the pump flow becomes too low – if, for example, the extension hose becomes kinked or blocked – then a pump alarm is activated on the device. Dräger X-am 1/2/5000 pump 5.9 Probes Probes, sometimes combined with extension hoses, are needed whenever leakages must be measured in inaccessible places, or when people are about to enter confined spaces. NAME Bar probe 400 GL probe (German Lloyd probe) Leakage probe 70 Bar probe 90 Telescopic probe 100 ORDER NUMBER 83 17 188 64 08 160 83 16 531 83 16 532 83 16 530 D-25398-2009 D-25393-2009 ST-14995-2008 D-25396-2009 ST-14992-2008 Flexible metal tube with an integrated Viton hose.

FOR USE WITH GAS DETECTION DEVICES USES 280| Accessories | 281 5.10 Extension hoses Whenever the air quality has to be assessed at a distance, such as on the floor of a silo, at the bottom of a loading chamber on a ship, or in a sewage system, then extension hoses and pumps are needed. There are two important factors – the length of the hose and the material it is made of. The power of the pump is crucial when deciding on the length of the hose. The Dräger X-am 1/2/5000 external pump and the pump intregrated in the Dräger X-am 3000 are designed for hoses with a length of up to 20 m (66 ft.). The Dräger X-am 7000 integrated pump is suitable for hose up to a length of 45 m (148 ft.). When choosing the hose material, you must be aware of the way the gases you are measuring are absorbed into the surface of the hose. Three different types of hose material have proven practical, each being suitable for particular groups of gases. The following table should help you to decide which type of hose to use.

This software application enables Dräger gas detection devices to be configured and adjusted professionally. For instance, it enables some of the device’s settings to be adjusted to the application on hand, and the sensors to be calibrated. The functions of the device are shown clearly on the screen in a tree structure, allowing quick, customized adjustment of the device’s parameters, and calibration of the sensors as well. The software also helps to manage measurment data, thus enabling quick access to any reports you might need to locate. 5.12 Dräger GasVision This software allows you to depict the measurement data stored in a device in table or graphic form. It shows an exposure curve for each sensor as an overview, from which segments can be extracted. This visualization enables hazardous situations to be recognized, and action to be taken accordingly. Comments about the place of measurement, the personnel, and other relevant data can be added to the records, allowing you to create complete documentation of the situation in a workplace. Closing comments This chapter only covers a part of our comprehensive range of accessories. As well as pumps, calibration, and communication accessories, we also offer a large range of bags and cases (equipped and empty), and a range of power supply units – meaning that you can adapt your accessories to any application. Our gas detection equipment is also complimented by our services such as maintenance contracts, full service agreements, and complete worry-free packages, as well as training courses such as device maintenance courses. Our staff at our branch offices will gladly advise you further about these products and services. lorem isum HEADQUARTERS Dräger Safety AG & Co.
