The Orion
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 Orion 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.
• 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.
• Check pump (if used) for proper operation before each
days use.
• 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 sensors.
• Do not place end of sampling line in liquids.
• Wait for accurate reading; response times vary, based on
gas/vapor and length of sampling line.
