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
vapours as well as low level of oxygen.
• Determine the appropriate gas and vapour monitoring needed for
a workplace.
The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors can be equipped to detect:
• Combustible gases and certain combustible vapours
• Oxygen-deficient or oxygen-rich atmospheres
• Specific toxic gases for which a sensor is installed.
The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors are designed to:
• Detect gases and vapours in air only
• Detect only specified toxic gases for which a sensor is installed (available
sensors see Chapter 6).
While the instrument can detect up to 25 % oxygen in ambient air, it is
approved for use only up to 21 % oxygen.
• 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 sulphide, or high contaminant levels.
• Recheck calibration if unit is subjected to physical shock.
• Use only to detect gases/vapours for which a sensor is installed.
• Do not use to detect combustible dusts or mists.
• Make sure adequate oxygen is present.
• Do not block sensors.
• Never block the pump inlet except to perform a sampling safety test.
• Have a trained and qualified person interpret instrument readings.
• Do not remove battery pack from instrument while in a hazardous location.
• Do not recharge Li Ion battery in a combustible location.
• Do not replace alkaline batteries in a combustible location.
• Do not alter or modify instrument.
• Use only MSA-approved sampling lines.
