The BS EN 60079-29-2:2015 standard provides guidance and recommended practices for the selection, installation, use, and maintenance of electrically operated gas detectors used in industrial and commercial safety applications. It is also applicable to underground coal mines where flammable gases need to be monitored. The standard covers the detection and measurement of flammable gases and oxygen, as well as the inertization process in which oxygen is excluded to prevent explosions.

The standard applies to equipment, instruments, and systems that use electrical signals from gas sensors to indicate the presence of a flammable or potentially explosive gas-air mixture. These devices can provide meter readings, activate alarms, or trigger safety precautions such as plant shutdown or evacuation. The standard is applicable to fixed installations, transportable equipment, and portable equipment. It also provides additional guidance for equipment that detects oxygen deficiency or specific toxic gases.

Flammable gases in this standard include flammable vapors, while mists are not covered due to measurement limitations. The standard applies to Group II equipment used in industrial and commercial safety applications and Group I equipment. It includes fixed equipment, transportable equipment, and portable equipment. However, it does not cover equipment for detecting non-flammable toxic gases, laboratory equipment for analysis or measurement purposes, equipment for process control applications, equipment for explosives processing and manufacture, or equipment for detecting explosive atmospheres resulting from dust or mist in the air.
