Safety and Precautionary Measures
|
•
|
Check function (0.1 Function Tests) each day before use. MSA recommends carrying out a routine inspection prior to each day's use. |
|
•
|
Perform a Bump Test before each day's use ( Bump Test) to verify proper device operation. The device must pass the bump test. If it fails the test, perform a calibration ( 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: |
|
○
|
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 XXX indicates the atmosphere is above 100% LEL or 5.00%vol CH4,and an explosion hazard exists. Move away from hazardous area immediately. |
|
•
|
Allow sufficient time for device to display accurate reading. Response times vary based on the type of sensor being utilized ( Performance Specification). |
WARNING!
Carefully review the following safety limitations and precautions before placing this device in service. Incorrect use can cause death or serious personal injury.
|
•
|
Do not use the ALTAIR 4X 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 |
|
○
|
Atmospheres containing combustible airborne mists/dusts. |
|
•
|
Do not use the ALTAIR 4X 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. |
|
•
|
Recheck calibration if device is subjected to physical shock, or is completely submerged underwater. |
|
•
|
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. |
|
•
|
All device readings and information must be interpreted by someone trained and qualified in interpreting device readings in relation to the specific environment, industrial practice and exposure limitations. |
Failure to follow these warnings can result in serious personal injury or death.
WARNING!
Risk of explosion: Do not recharge device in hazardous area.
Failure to follow this warning can result in serious personal injury or death.
Use only battery chargers made available by MSA for use with this instrument; other chargers may damage the battery pack and the unit. Dispose of in accordance with local health and safety regulations.Use of the GALAXY Automated Test System is an alternate approved method for charging ALTAIR 4X instruments.
Environmental Conditions
A number of environmental factors may affect the sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes also affect the amount of oxygen actually present in the atmosphere.
Procedures for Handling Electrostatically Sensitive Electronics
The device contains electrostatically sensitive components. Do not open or repair the device without using appropriate electrostatic discharge (ESD) protection. The warranty does not cover damage caused by electrostatic discharges.
Product Regulations
Follow all relevant national regulations applicable in the country of use.
