1.1. Correct Use

The ALTAIR 4X Multigas Detector is for use by trained and qualified
personnel. It is 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 4X Multigas Detector can be equipped to detect:
Combustible gases and certain combustible vapors
Oxygen-deficient or oxygen-rich atmospheres
Specific toxic gases for which a sensor is installed.
NOTE: While the instrument can detect up to 30% oxygen in ambient
air, it is approved for use only up to 21% oxygen.
Read and follow all instructions carefully.
Perform a bump test before each day's use and adjust if
necessary.
Perform a bump test 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.
Make sure adequate oxygen is present for accurate
combustible readings (>10% O 2 ).
Do not block sensors.
Have a trained and qualified person interpret instrument
readings.
