1.2 Safety and Precautionary Measures to be Adopted
Attention!
Carefully review the safety limitations and precautions in this
section before placing this instrument in service. Incorrect use
can cause serious personal injury or death.
Check function (see section 3.6) each day before use. MSA recommends
carrying out a routine inspection prior to each day's use.
Perform a Bump Test (see section 3.8) before each day's use to verify
proper instrument operation. The instrument must pass the bump test. If it
fails the test, perform a calibration (see section 3.9) before using the
instrument.
Perform a bump test more frequently if the unit 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.
