There is a saying that fire extinguishers can only be stored at room temperature, is that true? But fire extinguishers can play a huge role in car fires. So should there be a fire extinguisher in the car?
First and foremost, it won't explode! Won't explode! Won't explode!
General vehicle fire extinguishers are dry powder fire extinguishers or water-based fire extinguishers, so for this kind of fire extinguisher, the factor that can make it explode is high pressure. So what is the pressure of a normal fire extinguisher? How much pressure can it explode?
The water-based fire extinguishers of Wai Kee Hang can be used at a temperature of 5°C to 55°C and dry powder at -20°C to 55°C. And normal fire extinguishers, within the scope of the national standard, are qualified to burst when they reach 5.5MPa, and how much temperature is required to cause such a large pressure?
The answer is 239.75°C.
This temperature is also difficult to achieve in the sun. Therefore, unless the vehicle spontaneously ignites, it is difficult for a qualified fire extinguisher placed in the car to explode only by the high temperature of the sun exposure.
Therefore, whether it is water-based or dry powder, whether it is placed in the trunk or on the seat, the safety of genuine fire extinguishers is guaranteed.
