Safety Limitations And Precautions; Warning - MSA Sirius Manual De Operación

• 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.
