Will a Fire Extinguisher Explode in a Car?
1 Answers
During summer, temperatures can be quite high, with outdoor temperatures reaching 35°C or even higher. However, since fire extinguishers are typically stored in the trunk, which provides some insulation, there is generally no risk of explosion. Below is a detailed explanation regarding whether a fire extinguisher can explode in a car: 1. Pay attention to the pressure gauge on the fire extinguisher: If the needle is in the green zone or slightly yellowish-green, it indicates normal pressure and the extinguisher is safe to use. If it's in the yellow zone, the pressure is too high—while it can still be used, there is some risk, and it's best to have it inspected. If it's in the red zone, the pressure is too low and the extinguisher must be refilled or replaced. It is recommended to refill or replace car fire extinguishers annually. 2. Type of fire extinguisher: Most vehicle fire extinguishers are dry powder types. Theoretically, dry powder extinguishers can withstand temperatures between -20°C and 55°C, so they won't explode under normal car conditions. However, this doesn't mean fire extinguishers can be stored carelessly in the car. Although the cylinder itself won't explode, excessively high temperatures can accelerate the aging of the extinguisher's components, leading to leaks and rendering the extinguisher ineffective.
