1.3

Safety and Precautionary Measures

Carefully review the following safety limitations and precautions before placing this device in service.
Incorrect use can cause death or serious personal injury.
-
Check function (see chapter 3.8) each day before use. MSA recommends carrying out a routine
inspection prior to each day's use.
-
It is recommended that a Bump Test is performed (see chapter 3.9) before each day's use to verify
proper device operation. The device must pass the bump test. If it fails the test, perform a calibra-
tion (see chapter 3.10) before using the device.
-
The ALTAIR 5X MultiGas Detectors are designed to detect gases and vapors in air only.
-
Bluetooth Operation is dependent upon signal availability of the wireless service(s) necessary to
maintain the communication link. Loss of wireless signal will prevent communication of alarms and
other information to linked devices. Take appropriate precautions in the event a loss of wireless
signal occurs.
Perform a Bump Test more frequently if the device is subjected to physical shock or high levels of
contaminants. Also, check calibration more frequently if the tested atmosphere contains the following
materials, which may desensitize the combustible gas sensor and reduce its readings:
-
Organic silicones
-
Silicates
-
Lead-containing compounds
-
Sulfur compound exposures over 200 ppm or exposures over 50 ppm for one minute.
-
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
100 % LEL, and an explosion hazard exists. Move away from hazardous area immediately.
-
Do not use the device to test for combustible or toxic gases in the following atmospheres as this
may result in erroneous readings:
-
Oxygen-deficient or oxygen-rich atmospheres
-
Reducing atmospheres
-
Furnace stacks
-
Inert environments (only IR sensors acceptable for use)
-
Atmospheres containing combustible airborne mists/dusts.
-
Do not use the ALTAIR 5X and ALTAIR 5X IR Multigas Detectors to test for combustible gases
in atmospheres containing vapors from liquids with a high flash point (above 38 °C, 100 °F) as this
may result in erroneously low readings.
-
Allow sufficient time for device to display accurate reading. Response times vary based on the
type of sensor being utilized (→ chapter 5.2). Allow a minimum of 1 second per foot (3 seconds
per meter) of sample line to allow the sample to be drawn through the sensors.
-
Sampling lines made from 0.062 inch (1.57 mm) inner diameter tubing provide fast transport times
to the device; however, they must be limited to 50 feet (15 m) in length.
-
Sampling of reactive toxic gases (Cl
line and probe kits listed in chapter 8.
-
All device readings and information must be interpreted by someone trained and qualified in inter-
preting device readings in relation to the specific environment, industrial practice and exposure
limitations.
