Gas Test Atmospheres

To test the atmosphere in a confined space before entry to ensure it is safe to enter.

Gas hazards are unpredictable and confined spaces are dangerous, making it very important for an initial gas test in the confined space prior to entry and to continuously monitor gas levels with a gas monitor. Monitors not only tell workers whether the atmosphere in a confined space is safe, but also how safe. Gas tests must be performed at 3 levels of the confined space as every gas has different properties and some are heavier than air and some are lighter than air.

Testing the working atmosphere to determine if it is safe for the proposed work. Testing involves the use of electronic test apparatus.

Your Statement of Attainment does not have an expiry date, however, industry standards recommend retraining every two years.

To detect a gas which is lighter than air, place the detector at a high level. To detect a gas which is heavier than air, place the detector at a low level. If the gas density is close to air density, place detectors at both high, mid and low levels. Gas density increases when the temperature decreases.
