1 Safety Regulations
1.1 Correct Use
The ALTAIR 4X Multigas Detector is intended for use by trained and qualified per-
sonnel. It is designed to be used when performing a hazard assessment to:
- assess potential worker exposure to combustible and toxic gases and vapours
as well as low level of oxygen.
- determine the appropriate gas and vapour monitoring needed for a workplace.
The ALTAIR 4X Multigas Detector can be equipped to detect:
- Combustible gases and certain combustible vapours
- Oxygen-deficient or oxygen-rich atmospheres
- Oxygen for monitoring inertisation applications. The device is suitable and cer-
tified for the measurement of the oxygen concentration in gas mixtures for iner-
tisation according to EN 50104 but without alarm function.
- Specific toxic gases for which a sensor is installed.
It is imperative that this operating manual be read and observed when using the
product. In particular, the safety instructions, as well as the information for the use
and operation of the product, must be carefully read and observed. Furthermore,
the national regulations applicable in the user's country must be taken into account
for a safe use.
The ATEX directive is only valid until 25% Vol O2.
Alternative use, or use outside this specification will be considered as non-compli-
ance. This also applies especially to unauthorised alterations to the product and to
commissioning work that has not been carried out by MSA or authorised persons.
Danger!
This product is supporting life and health. Inappropriate use, mainte-
nance or servicing may affect the function of the device and thereby se-
riously compromise the user's life.
Before use the product operability must be verified. The product must
not be used if the function test is unsuccessful, it is damaged, a compe-
tent servicing/maintenance has not been made, genuine MSA spare
parts have not been used.

1.2 Liability Information
MSA accepts no liability in cases where the product has been used inappropriately
or not as intended. The selection and use of the product are the exclusive respon-
sibility of the individual operator.
Product liability claims, warranties also as guarantees made by MSA with respect
to the product are voided, if it is not used, serviced or maintained in accordance with
the instructions in this manual.
1.3 Safety and Precautionary Measures to be Adopted
Check Function
Before each day’s use, check the function of the device (chapter 3.6).
MSA recommends carrying out a routine inspection prior to each day’s use.
Perform a bump test
Bump test frequency is often stipulated by national or corporate regulations; how-
ever, bump testing before each day´s use is generally the accepted best safety
practice and is therefore MSA’s recommendation. The device must pass the bump
test. If it fails the test, perform a calibration before using the device.
Perform a bump test more frequently if the device is subjected to physical shock or
high levels of contaminants. Also, perform a bump test more frequently if the tested
atmosphere contains the following materials, which may desensitize the combusti-
ble gas sensor and reduce its readings:
- Organic silicones
- Silicates
- Lead-containing compounds
- Hydrogen sulphide exposures over 200 ppm or exposures over 50 ppm for
one minute.
Check minimum concentration of a combustible gas
The minimum concentration of a combustible gas in air that can ignite is defined as
the Lower Explosive Limit [LEL]]. A combustible gas reading of "XXX” indicates the
atmosphere is above 100 % LEL or 5.00 % vol CH4, and an explosion hazard ex-
ists. Move away from hazardous area immediately.
Attention!
The following safety instructions must be observed implicitly. Only in this
way can the safety and health of the individual operators, and the correct
functioning of the device, be guaranteed.

MSA
Safety Regulations
ALTAIR 4X
8GB
Observe atmosphere
Do not use the device to test for combustible or toxic gases in the following atmos-
pheres as this may result in erroneous readings:
- Oxygen-deficient or oxygen-rich atmospheres
- Reducing atmospheres
- Furnace stacks
- Inert environments
- Atmospheres containing combustible airborne mists/dusts.
Use the device only to detect gases/vapours for which a sensor is installed.
The device is suitable and certified for the measurement of the oxygen concentra-
tion in gas mixtures for inertisation according to EN 50104 but without alarm func-
tion.
Make sure adequate oxygen is present for accurate combustible readings with the
catalytic sensor (>10% O2).
Not to be used for gases having a flashpoint in excess of 38 °C
Do not use the device to test for combustible gases in atmospheres containing va-
pours from liquids with a high flash point [above 38 °C], as this may result in erro-
neously low readings.
Physical shock
Recheck calibration if device is subjected to physical shock.
Sensor maintenance
Do not block sensor openings as this may cause inaccurate readings. Do not press
on the face of the sensors, as this may damage them and cause erroneous read-
ings. Do not use compressed air to clean the sensor holes, as the pressure may
damage the sensors.
Observe Proper Time for Display Stabilising
Allow sufficient time for device to display accurate reading. Response times vary
based on the type of sensor being utilized.

Observe proper battery maintenance
Use only battery chargers made available by MSA for use with this device; other
chargers may damage the battery pack and the device. Dispose of in accordance
with local health and safety regulations.
Use of the GALAXY GX2 Automated Test System is an alternate approved method
for charging ALTAIR 4X devices.
Be aware of environmental conditions
A number of environmental factors may affect the sensor readings, including
changes in pressure, humidity and temperature.
Pressure and humidity changes also affect the amount of oxygen actually present
in the atmosphere.
Be Aware of the Procedures for Handling Electrostatically Sensitive
Electronics
The device contains electrostatically sensitive components. Do not open or repair
the device without using appropriate electrostatic discharge (ESD) protection. The
warranty does not cover damage caused by electrostatic discharges.
Be Aware of the Product Regulations
Follow all relevant national regulations applicable in the country of use.
Be Aware of the Warranty Regulations
The warranties made by Mine Safety Appliances Company with respect to the prod-
uct are voided if the product is not used and maintained in accordance with the in-
structions in this manual. Please protect yourself and others by following them. We
encourage our customers to write or call regarding this equipment prior to use or for
any additional information relative to use or service.
