Instrument Safety; Correct Use - MSA ALTAIR 5 Manual De Funcionamiento

1. Instrument Safety

1.1. Correct Use

The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors are for use by
trained and qualified personnel. They are designed to be used when
performing a hazard assessment to:
• Assess potential worker exposure to combustible and toxic gases and vapors as well as low level of oxygen.
• Determine the appropriate gas and vapor monitoring needed for a
workplace.
The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors can be equipped
to detect up to five gases in the ALTAIR 5 and up to six gases in the
ALTAIR 5 IR:
• Combustible gases and certain combustible vapors
• Oxygen-deficient or oxygen-rich atmospheres
• Specific toxic gases for which a sensor is installed.
While the instrument can detect up to 25 % oxygen in ambient air, it is
approved for use only up to 21 % oxygen.
The ALTAIR 5 IR Gas Detector contains one Infrared sensor to detect
either CO 2 or specific combustible gases up to 100% volume, in
addition to up to five other gases.
Read and follow all instructions carefully.
• Perform a blocked flow test before each day's use if
equipped with an integral pump.
• Check calibration before each day's use and adjust if
necessary.
• Check calibration more frequently if exposed to silicone,
silicates, lead-containing compounds, hydrogen sulfide, or
high contaminant levels.
• Recheck calibration if unit is subjected to physical shock.
• Use only to detect gases/vapors for which a sensor is
installed.
• Do not use to detect combustible dusts or mists.
