Chapter 1,
Instrument Safety and Certifications
The Sirius 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
• Determine the appropriate gas and vapor monitoring needed for a
workplace.
The Sirius Multigas Detector can be equipped to detect:
• Combustible gases and certain combustible vapors
• Volatile organic compounds (VOCs)
• Oxygen-deficient or oxygen-rich atmospheres
• Specific toxic gases for which a sensor is installed.
• Read and follow all instructions carefully.
• 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.
• Make sure adequate oxygen is present.
• Do not block pump sample inlet.
• Use only Teflon sampling lines for reactive gases such as
Cl2, PH3, NH3, HCN, and for semivolatile organic compounds
such as gasoline and jet fuels.
• Use only MSA-approved sampling lines.
• Do not use silicone tubing or sampling lines.
• Wait sufficient time for the reading; response times vary,
based on gas/vapor and length of sampling line.
""WARNING

1-2
• Have a trained and qualified person interpret
instrument readings.
• Account for sensor reproducibility.
• Properly identify the VOC gas being measured before using
VOC response factors or setting alarm values (exposures,
STEL, TWA).
• Recognize that the VOC Auto-range displays readings in
increments of 100 ppb.
• Ensure installed PID bulb corresponds to the PID bulb
setting on the instrument display.
• Do not remove battery pack from instrument while in a
hazardous atmosphere.
• Do not take spare battery packs into a hazardous
atmosphere. Battery packs must be properly attached to the
instrument at all times.
• When they are to be discarded, properly dispose of alkaline
cells and the Li-Ion battery pack.
• Do not recharge Lithium Ion battery or change Alkaline
batteries in a hazardous location.
• Do not alter or modify instrument.
INCORRECT USE CAN CAUSE SERIOUS PERSONAL
INJURY OR DEATH.
Safety Limitations and Precautions
It is very important to have an understanding of PID basics
when changing your PID settings. Failure to properly identi-
fy the VOC gas being measured and/or failure to select the
correct Response Factor alarm values (exposure, STEL,
TWA) that match your desired Response Factor and/or the
correct bulb, will result in erroneous readings that could
lead to serious injury or death.
Carefully review the following safety limitations and precautions before
placing this instrument in service:
• The Sirius 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.
