1. Instrument Safety
1.1. Correct Use
The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors are for use by
trained and qualified personnel. They are designed to be used when
performing a hazard assessment to:
• Assess potential worker exposure to combustible and toxic gases
and vapors as well as low level of oxygen.
• Determine the appropriate gas and vapor monitoring needed for a
workplace.
The ALTAIR 5 and ALTAIR 5 IR Multigas Detectors can be equipped
to detect up to five gases in the ALTAIR 5 and up to six gases in the
ALTAIR 5 IR:
• Combustible gases and certain combustible vapors
• Oxygen-deficient or oxygen-rich atmospheres
• Specific toxic gases for which a sensor is installed.
While the instrument can detect up to 25 % oxygen in ambient air, it is
approved for use only up to 21 % oxygen.
The ALTAIR 5 IR Gas Detector contains one Infrared sensor to detect
either CO2or specific combustible gases up to 100% volume, in
addition to up to five other gases.
Read and follow all instructions carefully.
• Perform a blocked flow test before each day's use if
equipped with an integral pump.
• 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.
"WARNING

• Make sure adequate oxygen is present.
• Never block sensors.
• Never block pump inlet, except to perform sampling
safety test.
• Have a trained and qualified person interpret instrument
readings.
• Do not remove battery pack from instrument while in a
hazardous location.
• Do not recharge Li Ion battery in a hazardous location.
Risk of explosion may occur.
• Do not replace alkaline batteries in a hazardous location.
• Do not alter or modify instrument.
• 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 and length of sampling line.
• Do not use the instrument with integral pump for
prolonged periods in an atmosphere containing a
concentration of fuel or solvent vapors that may be
greater than 10%LEL.
INCORRECT USE CAN CAUSE SERIOUS PERSONAL INJURY OR DEATH.
This Class A digital apparatus complies with Canadian ICES-003.
For users in Australia/ New Zealand: The charge cradle is a Class A
product. In a domestic environment, this product may cause radio
interference, in which case, the user may be required to take adequate
measures.
1.2. Safety and Precautionary Measures
Carefully review the following safety limitations and
precautions before placing this instrument in service.
Incorrect use can cause serious personal injury or death.
The Altair 5 Multigas Detector is designed to:
• Detect gases and vapors in air only
"WARNING
1-2

• Detect only specified toxic gases for which a sensor is installed.
(for available sensors,see Section 5.3)
• Perform a blocked flow test (see section 4.2) before each day's
use if equipped with an integral pump.
• MSA recommends to check the instrument's functionality
(see section 3.6) and carry out a routine inspection each day
before use.
• Perform calibration check (see section 3.7) before each day's use
to verify proper instrument operation. Adjust calibration if the
readings are not within the specified limits.
• Check calibration more frequently if 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.
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 "5.00” indicates the atmosphere is above 100 % LEL or 5.00
%vol CH4, and an explosion hazard exists. Move away from hazardous
area immediately.
Do not use the ALTAIR 5 or ALTAIR 5 IR Multigas Detectors 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 (only IR sensors acceptable for use)
• Atmospheres containing combustible airborne mists/dusts.
Do not use the ALTAIR 5 or ALTAIR 5 IR Multigas Detectors to test for
combustible gases in atmospheres containing vapors from liquids with a
high flash point (above 38 °C, 100°F) as this may result in erroneously
low readings.
1-3

Do not block sensor openings as this may cause inaccurate readings.
Do not press on the face of the sensors, as this may damage them and
cause erroneous readings. Do not use compressed air to clean the
sensor holes, as the pressure may damage the sensors.
Allow sufficient time for unit to display accurate reading. Response
times vary based on the type of sensor being utilized (see Section 5.3,
"Sensor Performance Specifications"). For units with a sample pump,
allow a minimum of 1 second per foot (3 seconds per meter) of sample
line to allow the sample to be drawn through the sensors.
Sampling lines made from 0.062 inch (1.57 mm) inner diameter tubing
provide fast transport times to the instrument; however, they must be
limited to 50 feet (15 m) in length.
Sampling of reactive toxic gases (Cl2, ClO2, NH3) must only be done
with the reactive gas sample line and probe kits listed in the
Accessories table in Section 6.2.
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.
Observe proper battery maintenance
Use only battery chargers made available by MSA for use with this
instrument; other chargers may damage the battery pack and the
instrument. Dispose of in accordance with local health and safety
regulations.
Be aware of environmental conditions
A number of environmental factors may affect the oxygen and toxic
sensor readings, including changes in pressure, humidity and
temperature. Pressure and humidity changes affect the amount of
oxygen actually present in the atmosphere.
After exposure to negative (°C) temperatures, units with HCN (hydrogen
cyanide) sensors should be bump checked and calibrated, if necessary,
after returning to room temperature.
Be aware of the procedures for handling electrostatically sensitive
electronics
The instrument contains electrostatically sensitive components. Do not
open or repair the unit without using appropriate electrostatic discharge
(ESD) protection. The warranty does not cover damage caused by
electrostatic discharges.
