Exposure to toxic gases can also occur in operations such as painting, fumigation, fuel filling, construction, excavation of contaminated soils, landfill operations, entering confined spaces, etc. Common sensors include combustible gas sensors, photoionization detectors, infrared point sensors, ultrasonic sensors, electrochemical gas sensors, and metal-oxide-semiconductor sensors (MOS sensors).
Electrochemical gas sensors are gas detectors that measure the concentration of a target gas by oxidizing or reducing the target gas at an electrode and measuring the resulting current.

Gas leak

This type of equipment is used to detect a gas leak or other emissions and can interface with a control system so a process can be automatically shut down. Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors.
In 2012, Boston University professor Nathan Phillips and his students drove along all 785 mi of Boston roads with a gas sensor, identifying 3300 leaks.
