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
Cl 2 , PH 3 , NH 3 , 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.
