Power generation sites
Generation of toxic gases and leaks of combustible gases used as raw material can pose various hazards at thermal power and biomass power generation sites. Each process relies on gas detectors to prevent accidents.

Thermal power station sites (natural gas fired GTCC power generation)
Coal silo
Coal transported by coal vessels is transferred via belt conveyor to the coal silo for temporary storage.
HazardsCoal may react with moisture and oxygen to generate heat. (Self heating) If self heating continues and heating increases heat generation, the temperature may rise, causing the coal to ignite. (Self ignition) Self heating generates both carbon monoxide (CO) and carbon dioxide (CO2) together with heat.

Other power generation sites (Biogas power generation)
Biogas power generation systems extract combustible biogas (methane) from fermented organic waste material (e.g., cattle manure, waste food material, sewage); this biogas drives gas engines or gas turbines to generate electricity.
HazardsTake precautions to prevent leaks of methane biogas (CH4).

Other power generation sites (wood biomass gasification power generation)
Wood biomass gasification power generation generates electricity by converting wood chips and similar materials into gas at high temperature, then burning this gas in a gas engine or gas turbine.
HazardsTake precautions to prevent gas leaks. The woody biogas produced by thermal decomposition contains high concentrations of gases such as carbon monoxide (CO) and hydrogen (H2).

Other power generation sites (geothermal power generation)
Geothermal power generation generates electricity by using steam from geothermal fluid extracted from geothermal reservoirs 1,000 to 3,000 m below the surface to rotate a turbine.
Geothermal fluid and the steam produced contains various substances, including carbon dioxide (CO2), hydrogen sulfide (H2S), ammonia (NH3), methane (CH4), and sulfur dioxide (SO2).
HazardsTake precautions to prevent leaks from the various processes within the plant. The steam from geothermal fluid contains toxic gases.

Gas detectors are used in applications like these...
Fixed gas detectors are recommended for the following applications:
- ・ For checking the safety of work environments in which workers are present
- ・ For checking safety in locations where gas may accumulate, such as pits and enclosed spaces
- ・ For detecting leaks from plant and equipment
Portable gas detectors are recommended for the following applications:
- ・ For strengthening safety measures for workers
- ・ For managing safety using objective figures, from checking for residual gas before maintenance and inspection work to confirming safety during work and checking sealing conditions at pipe unions
- ・ For identifying the locations of gas leaks if they occur
