There is never a bad time to check the status of your gas detection. Your safety depends on properly functioning equipment, and there are a number of variables to consider. Use the checklist below to help you stay prepared.
- Are your sensors still under warranty? While warranty expiration does not always mean the sensor isn’t functioning properly, older sensors should be watched extra closely. Oxygen sensors should be replaced upon expiration, since they are the most prone to failure after the warranty period elapses. Make sure to calibrate your meter regularly and always bump check your sensors before each days use.
- Is the pump on your meter functioning properly? The pump must work properly not only to sample the air around you, but to also ensure a proper calibration. To test, place your finger over the pump inlet. If the pump does not stall, the meter is not pulling a sufficient sample and the pump likely needs to be repaired.
- Do your rechargeable batteries last an entire shift? Batteries should typically run at least 8 hours on a full charge. Rechargeable batteries should be tested occassionally by charging the meter and letting it run until it shuts down. Alkaline batteries should be replaced when needed or annually at the very least.
- Are the filters clean and undamaged? Filters protect your meter from dust, dirt, and liquids. Change the filters when they look dirty or block flow of the pump. It is advisable to change filters regularly and always have spares on hand.
- Does your sample tubing look clean, not dirty or discolored? Tubing is used to draw air samples from remote areas up to the meter for detection. Dirty or discolored tubing can distort your readings and should be replaced. Be sure when sampling VOC’s or gases with low action levels that you are using Teflon tubing.
- Is your calibration gas still current and not expired? Each cylinder has a “Use Before” date on the label. Gas should never be used beyond this date, since there is no way to verify gas concentration still falls within the specifications on the label.
- Does the regulator indicate adequate pressure in your calibration cylinder? Low pressure readings indicate your gas cylinder is near empty. Even if the regulator gauge reads just above empty, it is generally a good idea to replace the gas, since low gas levels sometimes lead to lower concentrations in the gas cylinder.
