Related Laws and Disaster Prevention Measures
Fuel tanks installed in thermal power stations abide by the Fire Service Act, the Act on the Prevention of Disasters in Petroleum Industrial Complexes and Other Petroleum Facilities, and the High Pressure Gas Safety Act, etc. Measures for the tanks are taken based on the acts. With regards to power stations that fall under the Act on the Prevention of Disasters in Petroleum Industrial Complexes and Other Petroleum Facilities, depending on the scale, the following countermeasures are taken.
- Establishment of management systems through the appointment of a disaster prevention manager and a deputy disaster prevention manager and the creation of disaster prevention regulations
- Installation of disaster prevention facilities such as chemical fire trucks, oil recovery vessels, and oil fence expanding ships, as well as dispatching of necessary disaster prevention personnel, through self-defensive and collegial organizations for disaster prevention
- Establishment of reporting systems and other systems for disaster prevention
Contents of Measures
Thermal power stations mainly handle LNG (liquified natural gas), LPG (liquefied petroleum gas), and heavy crude oil. The following leakage and fire prevention measures are taken for such hazardous materials.
To prevent hazardous materials from firing, preventing three following conditions from establishing is important.
|The 3 Conditions for Fires and Explosions||Fire Prevention Measures|
|①Occurring in a Closed Space(Presence of Combustibles)||Installing fuel facilities in outdoors and not making in a closed space|
|②Flammable Gas Mixed with a Certain Ratio of Air(Presence of Oxygen)||
|③Presence of an Ignition Source||
In the unlikely event of a fire, facilities are arranged so that the heat and gas generated will not affect the outside of the premises. Prompt firefighting activities are also enabled by using fire prevention and extinguishing facilities on the premises and improving disaster prevention systems, including on-site self-defensive fire brigades in the power station grounds, firefighting vehicles, public firefighting, owning firetrucks for collegial disaster prevention, and disaster prevention vessels (when land transportation is cut off), etc.
[Main Facilities for Fire Prevention and Extinguishing]
- Foam Fire Extinguisher
- Sprinkler Facilities
- Drainage Facilities
- Inert Gas Extinguisher
- Water Curtain (LNG and LPG)
- Chemical fire extinguishing Facilities
- *Including chemical fire engines
