Safety Limitations And Precautions - MSA Solaris Manual De Operación

Safety Limitations and Precautions

Carefully review the following safety limitations and precautions before
placing this instrument in service:
• The Solaris Multigas Detector is designed to:
• Detect gases and vapors in air only
• Detect only specified toxic gases for which a sensor is
installed.
• Perform the following check before each day's use to verify proper
instrument operation:
• Calibration check (see Calibration Check section). Adjust
calibration if the readings are not within the specified limits.
• Check calibration more frequently if the unit 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
• Hydrogen sulfide 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" or "5.00" indicates the atmosphere is above
100% LEL or 5.00% CH 4 , respectively, and an explosion hazard
exists. In such cases, the instrument LockAlarm feature activates.
Move away from contaminated area immediately.
• Do not use the Solaris Multigas Detector 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
• Atmospheres containing combustible airborne mists/dusts.
