Instrument Safety; Correct Use - MSA ALTAIR 4X Manual De Funcionamiento

1. Instrument Safety

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.
