1.2. Safety and Precautionary Measures to be Adopted

MSA

WARNING

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

Detect only specified toxic gases for which a sensor is installed

(available sensors see Section 6).

Check function (see section 3.6) each day before use. MSA recommends carrying out a routine inspection prior to use each day before use.

Perform calibration check (see section 3.8) 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 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.

MSA

INSTRUMENT SAFETY

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 CH

4

, and an explosion hazard exists.

Move away from hazardous area immediately.

Do not use the ALTAIR 5 Multigas 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/dusts.

Do not use the ALTAIR 5 Multigas Detector 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.

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 5.4,

"Performance Specifications"). Additionally, when using 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.

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.

on the

Measuring page until another page is selected or the instrument is turned

OFF.

WARNING

If an alarm activates while using the instrument, leave the area immediately.

Remaining on site under such circumstances can cause serious damage to health or can even lead to death.

The instrument has two alarm setpoints:

HIGH Alarm

LOW Alarm

If the gas concentration reaches or exceeds the alarm setpoint, the instrument:

• backlight turns on displays and flashes the alarm message either LOW alarm or the

HIGH alarm

enters an alarm state.

When gas reading exceeds 100% COMB or 5.00% CH

4

, the instrument enters a Lock Alarm state and displays “XXX” in place of the actual reading. This state can only be reset by turning the instrument OFF and ON.

WARNING

A combustible gas reading of "XXX” indicates the atmosphere is above

100 % COMB or 5.00 %vol CH

and an explosion hazard exists. Move away from contaminated area immediately.

In such cases, the instrument LockAlarm feature activates.

US

ALTAIR 5 - Operating Manual

OPERATION MSA

3. Operation

Instrument operation is dialog driven from the display with the aid of the three Function buttons (see Section 2.2.1).

A number of environmental factors may affect the gas sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes affect the amount of oxygen actually present in the atmosphere.

Pressure Changes

If pressure changes rapidly (e.g., stepping through airlock) the oxygen sensor reading may temporarily shift, and possibly cause the detector to go into alarm. While the percentage of oxygen may remain at or near

20.8 vol%, the total amount of oxygen present in the atmosphere available for respiration may become a hazard if the overall pressure is reduced by a significant degree.

Humidity Changes

If humidity changes by any significant degree (e.g., going from a dry, air conditioned environment to outdoor, moisture laden air), oxygen readings can be reduced by up to 0.5 %, due to water vapor in the air displacing oxygen.

The oxygen sensor has a special filter to reduce the effects of humidity changes on oxygen readings. This effect will not be noticed immediately, but slowly impacts oxygen readings over several hours.

Temperature Changes

The oxygen sensor has built-in temperature compensation. However, if temperature shifts dramatically, the oxygen sensor reading may shift.

Zero the instrument at a temperature within 86°F (30°C) of the work site temperature for the least effect.

OPERATION

3.2.2 Fresh Air Setup (FAS)

The Fresh Air Setup (FAS) is for automatic ZERO calibration of the instrument.

The Fresh Air Setup (FAS) has limits. If a hazardous level of gas is present, the instrument ignores the FAS command and the instrument alarm activates.

Do not perform a Fresh Air Setup within 30 minutes of removing the instrument from charge. If the charge cycle is interrupted, do not perform a

Fresh Air Setup within 30 minutes. Fresh Air Setup can be performed immediately if the charge cycle was completed (4 hours for a fully discharged battery).

WARNING

Do not activate the Fresh Air Setup unless you are certain you are in fresh, uncontaminated air; otherwise, inaccurate readings can occur which can falsely indicate that a hazardous atmosphere is safe. If you have any doubts as to the quality of the surrounding air, do not use the Fresh Air Setup feature. Do not use the Fresh Air Setup as a substitute for daily calibration checks. The calibration check is required to verify span accuracy. Failure to follow this warning can result in serious personal injury or death.

The calibration check is simple and should only take about one minute.

Perform this calibration check before each day’s use for each installed sensor.

(1) Turn ON the ALTAIR 5 Multigas Detector in clean, fresh air.

(2) Verify that readings indicate no gas is present.

(3) Attach regulator (supplied with calibration kit) to the cylinder.

(4) Connect tubing (supplied with calibration kit) to the regulator.

(5) Attach other end of tubing to the instrument.

(6) Open the valve on the regulator, if so supplied.

The reading of the ALTAIR 5 Multigas Detector display should be within the limits stated on the calibration cylinder or limits determined by your company.

If necessary, change cylinder to introduce other calibration.

If readings are not within these limits, the ALTAIR 5 Multigas

Detector requires recalibration (see Section 3.9).

3.9. Calibration

CSA requires (per 22.2 NO. 152) that the instrument's sensitivity be tested before each day's use on a known concentration of methane equivalent to

25-50% of full scale concentration. Accuracy must be within 0 to +20% of actual. Correct accuracy by performing the calibration procedure within this manual.

The ALTAIR 5 can be calibrated either manually using this procedure or automatically using the GALAXY

TM

test stand. Refer to 7.7 of the appendix.

Calibration must be performed using a flow regulator with a flow rate set to

0.25 liters per minute.

After charging, wait 30 minutes before calibration to allow the instrument to return to normal temperature.

PUMP ERROR

PUMP ERROR

When the pump inlet, sample line or probe is blocked, the pump alarm must activate.

If the alarm does not activate: a. Check the sample line and probe for leaks. b. Once leak is fixed, recheck pump alarm by blocking the flow.

WARNING

Perform a blocked flow test before each day’s use. Do not use the pump, sample line, or probe unless the pump alarm activates when the flow is blocked. Lack of an alarm is an indication that a sample may not be drawn to the sensors, which could cause inaccurate readings.

Failure to follow the above can result in serious personal injury or death.

Never let the end of the sampling line touch or go under any liquid surface. If liquid is sucked into the instrument, readings will be inaccurate and instrument could be damaged. We recommend the use of an MSA sample probe (P/N 10042621, 10042622, 10040589, or equivalent) containing a special membrane filter, permeable to gas but impermeable to water, to prevent such an occurrence.
