Prevention of explosions
In the event of a gas leak, ventilate properly by letting indoor gas out. Refrain from using an electric switch or a heat source.
In confined spaces where a lot of dust is generated, install a dust collection system and avoid using heat-generating equipment.
Avoid excessive use of devices that are susceptible to overheating, e.g., home appliances and boilers. Habitually inspect such features as safety valves.
Avoid using batteries for devices like mobile phones and notebook computers for prolonged periods or in hot places. Do not keep such batteries together with metal materials and do not subject to excessive pressure.
Pierce a hole in explosive containers such as portable butane gas canisters and hair spray cans to discharge the remaining gas before discarding them.
Do not leave flammable or combustible materials such as gas lighters inside the car during the summer season.
When a suspected explosive is found, do not attempt to disassemble. Call the nearby police station or military unit.
If an explosion occurs
Swiftly evacuate the building to avoid possible secondary explosions.
During an explosion, the deafening sound may cause hearing impairment. Cover your ears as you evacuate.
Move to safety quickly, e.g. a place far away or behind a shield wall
Beware of flying shards and debris, and heed the wind direction to avoid asphyxiation from smoke or gas.
First, move injured persons to a safe place immediately, and then take emergency measures.
To prevent additional explosions, do not use electrical switches or heat-generating equipment. Shut off gas valves and open windows for natural ventilation.
