To ensure accurate and reliable measurements from air quality monitoring instruments, adhere to the manufacturer's recommended calibration frequency, as specified in a written schedule maintained by the employer. Conduct a bump test or calibration check of portable gas monitors before each day's use, according to the manufacturer's instructions. If any portable gas monitor fails a bump test or a calibration check, you must fully calibrate the monitor before further use, or remove it from service. [1] [1] [2] [2]
Calibration Types:
- Full Calibration - Adjusting the sensor's response to match the desired value compared to a known traceable concentration of test gas
- Calibration Check - Using a known traceable concentration of test gas to show that the sensors and alarms respond to the gas within manufacturer's acceptable limits
- Bump Test (Function Check) - Passing a known concentration of gas over the sensors at a level and exposure time strong enough to activate all alarms
Important Safety Note:
Always verify safety information with your organization's specific guidelines and local regulations.
