Instrument Safety and
Certifications
The Orion®G Multigas and Leak 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
•Determine the source of a gas leak.
The Orion G Multigas and Leak 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.
º
WARNING
•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 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.
Operating Manual Chapter 1, Safety Limitations and Certifications
1-1

•Do not place end of sampling probe in liquids.
•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.
•Do not replace alkaline cells in a combustible atmosphere.
•Do not recharge NiMH battery packs in a combustible
atmosphere.
•Do not alter or modify instrument.
INCORRECT USE CAN CAUSE SERIOUS PERSONAL INJURY
OR DEATH.
Safety Limitations and Precautions
Carefully review the following safety limitations and precautions
before placing this instrument in service:
•The Orion G Multigas and Leak 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 checks 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.
•Check pump for proper operation
(see "Verifying Pump Operation" section). Have pump
serviced if necessary.
•Check calibration more frequently if the unit is subjected to
physical shock or high levels of contaminants. Also, check
calibration more frequently if the tested atmosphere contains
the following materials, which may desensitize the combustible
gas sensor and reduce its readings:
•Organic silicones
•Silicates
•Lead-containing compounds
•Hydrogen sulfide exposures over 200 ppm or exposures
over 50 ppm for one minute.
Chapter 1, Safety Limitations and Certifications Operating Manual
1-2

•The minimum concentration of a combustible gas in air that can
ignite is defined as the Lower Explosive Limit (LEL). A
combustible gas reading of "100", or a %CH4reading within the
range of approximately 5% to 10% indicates that an explosion
hazard exists. Extreme caution must be exercised in this
situation.
•Do not use the Orion G Multigas and Leak Detector to test for
combustible or toxic gases in the following atmospheres as this
may result in erroneous readings:
•Oxygen-deficient or oxygen-rich atmospheres
•Reducing atmospheres
•Furnace stacks
•Inert environments
•Atmospheres containing combustible airborne mists
or dusts.
•Do not use the Orion G Multigas and Leak Detector to test for
combustible gases in atmospheres containing vapors from
liquids with a high flash point (above 100oF) as this may result
in erroneously low readings.
•Allow sufficient time for unit to display accurate reading.
Response times vary based on the type of sensor being utilized
(see "Performance Specifications" section of manual).
Additionally, allow a minimum of 0.7 seconds per foot of sample
line to allow the sample to be drawn through to the sensors.
•Keep the probe tip above liquid surfaces; otherwise, liquid may
enter the system and block the sample flow, causing inaccurate
readings and/or internal damage.
•All instrument readings and information must be interpreted by
someone trained and qualified in interpreting instrument
readings in relation to the specific environment, industrial
practice and exposure limitations.
•Replace alkaline cells or recharge NiMH battery-pack in
non-hazardous area only. Use only battery chargers listed in
this manual; other chargers may damage the battery pack and
the unit. Dispose of batteries in accordance with local health
and safety regulations.
•Do not alter this instrument or make any repairs beyond those
specified in this manual. Only MSA-authorized personnel may
repair this unit; otherwise, damage may result.
