Instrument Safety And Certifications - MSA SIRIUS Manual De Instrucciones

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 vapours
• 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 vapours
• Volatile organic compounds (VOCs)
• Oxygen-deficient or oxygen-rich atmospheres
• Specific toxic gases for which a sensor is installed.
ATTENTION:
• 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/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 pump sample inlet and sensors.
• Use only Teflon sampling lines for reactive gases such as Cl
for semivolatile organic compounds such as gasoline and jet fuels.
• Do not place end of sampling line in liquids.
• Use only MSA-approved sampling lines.
• Do not use silicone tubing or sampling lines.
• Wait for accurate reading; response times vary, based on gas/vapor and length of
sampling line.
• 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 recharge Lithium Ion battery or change Alkaline batteries in a combustible
atmosphere.
• Do not alter or modify instrument.
