Check function each day before use
Safety RegulationsMSA
Before each use, check the function and calibration of the device. Otherwise there
is a danger that incorrect results will be displayed. The check is performed using a
suitable calibration gas.
Perform a bump test each day before use
Perform a bump test before each day's use to verify proper operation. 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 combustible 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 CH
ists. Move away from hazardous area immediately.
