Wastewater Safety · Air Hazards and Gas Monitoring
How Are Gas Monitors Used?
A gas monitor is useful only when its sensors, settings, and use match the hazard.
A common multi-gas monitor checks oxygen, flammable gas, hydrogen sulfide, and carbon monoxide. Other chemicals may need different sensors. A standard monitor does not detect every vapor.
Check battery, sensor status, alarm settings, pump, tubing, filters, and calibration due date. Perform the required bump test before use. A bump test exposes sensors to known gas to confirm response and alarms.
Wear a personal monitor in the breathing zone as trained. Protect it from water and blockage. Do not cover the sensor openings with clothing. Respond to alarms; do not silence them and continue working.
Calibration and bump testing do different jobs. Calibration adjusts the monitor to known gas values. A bump test confirms that sensors, alarms, and flow respond. Follow the manufacturer and site schedule for both, and record failures before the monitor returns to service.
