Bump tests and calibrations are crucial factors in any gas detection program. But you also need to make sure you’re using good technique to consistently and accurately detect atmospheric hazards.
To have good technique, it’s necessary to understand gas detection and the limitations of your equipment. That said, consider the following five tips you can use for consistent and accurate gas detection.
- Use the filters recommended by the equipment manufacturer. Most meters will use a filter of some kind. This helps to keep out any dust or liquids, which could impair the internals of the meters. Without one, your meter is more likely to need a repair. Think of it as a smartphone without a security case. Use the filters recommended by the manufacturer and replace them regularly to keep your meter working.
- Test your meter pump. Not all meters have a pump, but if yours has one it’s a good idea to test it. Your meter can’t pull a sample if the pump is weak. To test the pump before using the monitor, place your finger over the inlet. The pump is good to go if the pump stall is triggered.
- Calibrate periodically. It’s vital that you’re calibrating periodically, although the timing for each calibration may vary depending on the recommendations of your manufacturers. Calibrations are quick and essential. They’re what ensures your gas meter reads are accurate when they’re exposed to gas. Without regular calibrations, you can’t be sure your meters are reading at all. Don’t trust a self-bump test, either.
- Do a bump test before every use. Speaking of bump tests, you want to be sure that you’re not just relying on fresh air values. If your meter sensor is damaged in some way or it no longer responds to gas, then that 0% LEL is worthless. Do a quick bump test to know if your sensors are working or not.
- Don’t use expired calibration gases. Calibration gases aren’t like milk. There’s no wiggle room with the expiration date. The expiration date on your calibration gas cylinders needs to be strictly followed. This is because calibration gas breaks down naturally on its own. This can make it impossible to perform a reliable calibration with it.
Where can I find calibration gas cylinders near me?
It’s estimated that 5.4 million U.S. businesses are powered by natural gas. No matter which industry you’re in, it’s important to make sure there aren’t any toxic or combustible substances in your workplace.
