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.

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.

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.

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.

IEC, NEC 505

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 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.

3.5 ATEX 95 – directive 94/9/EC
This directive applies to, among others, the manufacturers of gas detection and
warning instruments. 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:

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).

3.6 Laws and regulations in USA, Canada, and Mexico
Laws and regulations in most municipalities, states, and provinces in North America require
certain products to be tested to a specific standard or group of standards by a Nationally
Recognized Testing Laboratory (NRTL). 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,

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:

The Canadian Standards Association (CSA)
The Canadian Standards Association (CSA) is a not-for-profit association composed of
representatives from government, industry, and consumer groups. They are involved with many
diverse areas of specialization such as climate change, business management and safety and
performance standards, including those for electrical and electronic equipment, industrial
equipment, boilers and pressure vessels, compressed gas handling appliances, environmental
protection, and construction materials. CSA also provides advisory services, training materials
and print and electronic published standard documents. Currently forty percent of all the
standards issued by CSA are referenced in Canadian legislation.
CSA developed the CAN/CSA Z299 series of quality assurance standards still in use today.
They are an alternative to the ISO 9000 series of quality standards.
They do all of the review and testing for Intrinsic Safety and conduct performance testing. They
propose standards which are often codified into law or become de facto standards in Canada.
CSA is a recognized NRTL for testing and safety.
Mexican Safety and Health
Mexican Safety and Health is controlled by the Norma Official Mexicana (NOM) regulations.
Nom -005-STPS-1998 is very comparable to 29 CFR 1910.1200, the basic OSHA regulation
in the US. While using US OSHA regulations as a basis, the Mexican government has
implemented local requirements. They accept the testing and standards of any of the Nationally
Recognized Testing Labs.

3.7 Single-gas measuring instruments
ST-5619-2004
Brennbare und toxische Gase und Dämpfe kommen in vielen Bereichen vor. Die von ihnen ausgehende Gefahr gilt es zu erkennen – dazu dienen Gasmess- und warngeräte.
Hinsichtlich der messtechnischen und sicherheitstechnischen Belange soll dieser Faltprospekt
dem Leser gewisse Grundlagen der Gasmesstechnik vermitteln.
If the danger of toxic gases or vapors can be narrowed down to a single gas or
condustive component, then single-gas measuring and warning devices are the ideal
solution for personal monitoring in the workplace. They are small, robust, and
ergonomic. These devices are usually attached to the work clothing near the breathing
area, but do not limit the movement of workers. They monitor the ambient air
continuously and produce an alarm (visual, acoustic, and by vibration) if the gas
concentration exceeds an alarm limit preset in the device. This enables employees to
respond immediately to dangers if accidents occur during normal operation, or if
unforeseen events occur during maintenance and repair work.

Dräger Pac 3500–7000
The Pac 3500–7000 family is equipped with XXS sensors. These miniaturized
electrochemical sensors enable a small, ergonomic instrument design. The sensor sits right
behind a replaceable dust and water filter which protects it from outside influences, and yet
has a negligible effect on response times. Like accuracy and reliability, response time is a
crucial factor. The t90 to t20 times provide information about how quickly the sensor
responds to changes in gas concentration. Their fast response times and very small diffusion
paths enable these sensors to react extremely quickly, immediately indicating any danger that
arises. The electrical signal produced by the sensor is converted into a concentration
reading on the display by the unit’s electronics and software. Alarm thresholds are stored in
the unit (A1 = pre-alarm/A2 = main alarm). If gas concentrations exceed these alarm
thresholds, then the unit produces an acoustic, visual, and vibration alarm. Durability and
explosion protection are two other important factors when choosing the right gas detection
device.
Dräger X-am 5100
The Dräger X-am 5100 is designed for the measurement of the gases / vapors hydrazine,
hydrogen peroxide, hydrogen chloride and hydrogen fluoride. These special gas hazards are
difficult to detect because they adsorb to different surfaces. The open gas inlet projecting
from the device prevents that adsorbing surfaces are between the gas and the gas sensor.
A rapid response of the proven XS sensors is thus also ensured for these special gases.

The Dräger X-zone 5000 transforms the Dräger personal gas detection instruments
Dräger X-am 5000/5600 into innovative area monitoring devices for a wide range of
application.This gas measurement system is patented. With the 360°alarm amplifier, the
acoustic warning is heard with the same volume from all sides. X-zone 5000 affords a new
portable safety concept. Up to 25 Dräger X-zones can be automatically interconnected to form
a wireless fenceline. In the event of a gas alarm, the device transmits the alarm signal to all units
that are part of the fenceline which then signal a daughter alarm. The daughter alarm is, in
contrast to the red master alarm, displayed geen/red by the illuminated LED ring, thus allowing
and providing for a fast and easy recognitions of the alarm itself as well as of the alarm-trigging
devices. This ensures and easy and clear evacuation alarm and alerting. Via the potential-free
alarm contact, the Dräger X-zone 5000 device can also be interconnected and operate external
equipment such as alarm horns, lamps or traffic lights. Furthermore, the fenceline signal
together with the alarm contact can be forwarded to a control room - overseeing a wide range
of applications. Dräger X-zone 5000 as an area monitoring devices often stay located well within an explosion hazard area, even in during a gas alarm. It is therefore all the more important
the
devices are approved for use in explosion hazard areas, zone 0. The modern induction charger,
is simple to use, comfortable and has no problem with dirty charging contacts, so it is
maintenance friendly.

Leak detection
Durable, IP 67
Built-in high-performance pump makes it possible to
sample gas using a hose up to 45 m/150 ft. long.
Extensive portfolio of over 25 different
DrägerSensors enables the detection of more than
100 gases and vapors.
Smart Cat Ex sensors enable the detection of flammable gases and vapors, and can be
calibrated to as many as five different sensitivity levels. The unit can be switched
automatically from % LEL to 100 Vol.-% in full-range mode. Leakages are reliably detected,
visually in bar-graph mode and audibly in tracking mode.
The PID sensor detects organic vapors in very low concentrations. An integrated library of 20
substances, three user-adaptable channels, and an easy switch to leak detection mode makes
the instrument flexible enough to met your specific needs.
With the help of Dräger CC-Vision software, up to 5 different detection applications can be
saved within the instrument. By doing so, the use of different instrument configurations can
be set for that specific application. During operation, a simple change between these set
parameters can be done via the instrument's menu.
In addition to the electrochemical sensors, the catalytic and infrared sensors are automatically
recognized by the instrument upon insertion. All sensors are pre-calibrated, and therefore a
reconfiguration of the Dräger X-am 7000 can be done by simply changing the sensor. No
additional service or maintenance is necessary.

The response factors apply to a measurement range of 5 to 500 ppm and are based on
calibration with 100 ppm isobutylene. Response factor for isobutylene = 1.0. The response
factors are determined using the following formula:
Response factor =
Actual concentration
Displayed concentration
A response factor below 1 means that the compound is displayed with greater sensitivity than
isobutylene. A response factor above 1 means that the compound is displayed with less
sensitivity than isobutylene.
