Can Fire Extinguishers Explode in The Sun

In general, fire extinguisher exposure will not cause an explosion. However, prolonged exposure of a fire extinguisher to sunlight without proper maintenance can cause an explosion. At present, the fire extinguisher mostly adopts the design of high pressure gas built into the tank to drive the fire extinguishing agent. Improper maintenance of the fire extinguisher may lead to a decrease in stability due to the peeling and deformation of the bottle coating, resulting in an explosion caused by excessive high-pressure gas pressure.

Fire extinguishers generally do not explode when exposed to sunlight under normal conditions. Improper maintenance Exposure to sunlight may cause an explosion.

Fire extinguishers are designed to use high pressure gas to propel the extinguishing agent. Under normal maintenance, the high pressure gas will be controlled and protected, and ordinary sun exposure will not cause an explosion.

If the fire extinguisher is not maintained properly, resulting in poor stability, according to Charlie's law, when the volume of a certain mass of gas is constant, its pressure is proportional to the thermodynamic temperature, which means that the pressure inside the tank will increase with the temperature, which may lead to explosion.
