Safety of operation should always come first, so gas detectors are justified wherever leakage or even accumulation of unwanted gases could occur. This is primarily an explosion hazard that can be prevented by installing a gas leak detector. The advantage is the possibility to connect a safety device to shut off the gas supply, start automatic ventilation of the affected areas and alert the operator or make an acoustic or light warning signal.
Portable and stationary detectors are suitable for home use. Common applications are garages, boiler rooms, restaurants, etc. Mounting is possible for hanging.
