1.1

Correct Use

The ALTAIR 4X Multigas Detector is intended 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 as well as low level of oxygen.

- determine the appropriate gas and vapour monitoring needed for a workplace.

The ALTAIR 4X Multigas Detector can be equipped to detect:

- Combustible gases and certain combustible vapours

- Oxygen-deficient or oxygen-rich atmospheres

- Oxygen for monitoring inertisation applications. The device is suitable and certified for the measurement of the oxygen concentration in gas mixtures for inertisation according to EN 50104 but without alarm function.

- Specific toxic gases for which a sensor is installed.

It is imperative that this operating manual be read and observed when using the product. In particular, the safety instructions, as well as the information for the use and operation of the product, must be carefully read and observed. Furthermore, the national regulations applicable in the user's country must be taken into account for a safe use.

The ATEX directive is only valid until 25% Vol O

Liability Information

MSA accepts no liability in cases where the product has been used inappropriately or not as intended. The selection and use of the product are the exclusive responsibility of the individual operator.

Product liability claims, warranties also as guarantees made by MSA with respect to the product are voided, if it is not used, serviced or maintained in accordance with the instructions in this manual.

1.3

Safety and Precautionary Measures to be Adopted

Attention!

The following safety instructions must be observed implicitly. Only in this way can the safety and health of the individual operators, and the correct functioning of the device, be guaranteed.

Check Function

Before each day’s use, check the function of the device ( chapter 3.6).

MSA recommends carrying out a routine inspection prior to each day’s use.

Perform a bump test

Bump test frequency is often stipulated by national or corporate regulations; however, bump testing before each day´s use is generally the accepted best safety practice and is therefore MSA’s recommendation. The device must pass the bump test. If it fails the test, perform a calibration before using the device.

Perform a bump test more frequently if the device is subjected to physical shock or high levels of contaminants. Also, perform a bump test 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 sulphide exposures over 200 ppm or exposures over 50 ppm for one minute.

Check minimum concentration of a combustible gas

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 "XXX” indicates the atmosphere is above 100 % LEL or 5.00 % vol CH ists. Move away from hazardous area immediately.

Safety Regulations MSA

Observe atmosphere

Do not use the device 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.

Use the device only to detect gases/vapours for which a sensor is installed.

The device is suitable and certified for the measurement of the oxygen concentration in gas mixtures for inertisation according to EN 50104 but without alarm function.

Make sure adequate oxygen is present for accurate combustible readings with the catalytic sensor (>10% O

2

).

Not to be used for gases having a flashpoint in excess of 38 °C

Do not use the device to test for combustible gases in atmospheres containing vapours from liquids with a high flash point [above 38 °C], as this may result in erroneously low readings.

Physical shock

Recheck calibration if device is subjected to physical shock.

Sensor maintenance

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.

Observe Proper Time for Display Stabilising

Allow sufficient time for device to display accurate reading. Response times vary based on the type of sensor being utilized.

3 Operation

3.1

Environmental Factors

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 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 vapour 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 sensors have built-in temperature compensation. However, if temperature shifts dramatically, the sensor reading may shift. Zero the device at the work site temperature for the least effect.

If a sensor is nearing its end of life, this " SPAN PASS" indication will be followed by the end of sensor life warning [ symbol]. The  symbol, along with the gas type of the sensor nearing its end of life, will blink for 15 seconds when the device returns to measure mode. When in measure mode, the  symbol is continuously displayed.

Finishing Calibration

(1) Close the valve on the regulator.

(2) Remove the calibration cap.

The calibration procedure adjusts the span value for any sensor that passes the calibration test; sensors that fail calibration are left unchanged. Since residual gas may be present, the device may briefly go into an exposure alarm after the calibration sequence is completed.

Autocalibration Failure

Span calibration is unsuccessful:

- If the instrument cannot calibrate one or more sensor(s), it goes to the

SPAN ERR page and remains in alarm until the button is pressed.

- A sensor life indicator is displayed [Alarm symbol and  symbol] to show the sensor has reached its end of life and should be replaced.

This occurs if the span calibration is unsuccessful twice.

- The device will remain in alarm state until the  button is pressed.

- The Alarm symbol and  symbol will remain on the display until a successful calibration or sensor in question is replaced.

A span calibration can fail for many reasons besides sensor at the end of his life. If a span calibration failure occurs, items such as remaining gas in the calibration cylinder, gas expiration date, security of the calibration cap, etc. should be verified and calibration should be repeated prior to replacing the sensor.

Response notes

(1) Some compounds may reduce the sensitivity of the combustible gas sensor by poisoning orinhibiting the catalytic action or by polymerizing on the catalytic surface.

(2) Multiply the displayed %LEL value by the conversion factor above to get the true %LEL.

(3) These conversion factors should be used only if the combustible gas is known.

(4) All factors are based on the IEC 100% LEL levels

 i.e. Methane 100% LEL = 4.4 Vol%,

Pentane 100% LEL = 1.1 Vol%

Propane 100% LEL = 1.7 Vol%

(5) These conversion factors are typical. Individual units may vary by ±25% from these values.

GB

ALTAIR 4X

53

Technical Data MSA

(6) The results are intended for guidance only. For the most accurate measurements, an instrument should be calibrated using the gas under investigation.

(7) The conversion factors for the standard EX and the specialised EX-H and

EX-M sensor are the same except for EX-H and Nonane and o-Xylene. The conversion factors for these two vapours are therefore especially mentioned in the table.

Oxygen

The oxygen sensor has built-in temperature compensation. However, if temperature shifts dramatically, the oxygen sensor reading may shift. Zero the device at a temperature within 30 °C of the work place temperature for the least effect.
