Can Car Fire Extinguishers Explode?
4 Answers
Car fire extinguishers are basically dry powder extinguishers, and the storage temperature for this type of extinguisher is between -20°C and 55°C, so under normal circumstances, they will not explode. Precautions for storing car fire extinguishers: Need to be placed in a cool place: If the temperature is too high, it may cause some parts of the extinguisher to age, which can easily lead to leakage. Therefore, the storage location should avoid direct sunlight and be placed in a cool place. Place in an easily accessible position: Car fire extinguishers also need to be stored in a relatively convenient position because when a car fire is detected, you can quickly pick up the extinguisher to put out the fire. The volume of car fire extinguishers is usually relatively small, so they can be placed directly in the glove box or the luggage compartment of the passenger seat, and of course, they can also be placed under the seat.
Vehicle fire extinguishers are unlikely to explode under normal usage conditions, as they are equipped with pressure control designs and safety valve protections. However, improper storage—such as leaving them in a car where temperatures soar above 50°C in summer—can cause internal pressure to rise excessively, potentially leading to an explosion. Other risks include accidental placement near the engine hood where heat exposure occurs, or issues like aging canisters or dented containers. I recommend regularly checking the extinguisher’s pressure gauge to ensure it remains within the green safety zone and replacing it promptly when it expires. Storage location is also crucial—avoid direct sunlight and opt for cool spots like trunk corners or under seats. Safety comes first; small precautions prevent big troubles.
Having driven for over 30 years, I always keep a fire extinguisher in my car. I've never seen it explode, but a friend once forgot it on the rear window, and it nearly caused an accident due to high-temperature leakage. So my advice is: normal use won't make it explode, but high temperatures are its biggest enemy, especially in summer. I replace mine with a new one every two years—quality ones have protective mechanisms; don't cheap out on no-name brands. Choose a good spot, place it in a cool area inside the car, and check that the pressure gauge shows green for normal. For safety's sake, don't wait until it expires to deal with it.
As a mom who drives kids to school, I prioritize car safety. Car fire extinguishers don't explode without reason, so storing them properly gives peace of mind. However, high temperatures or collisions pose risks. In summer, I always check the car's interior temperature and keep the extinguisher in a shaded corner of the trunk. When purchasing, I choose certified brands and regularly check the expiration date. I teach my kids not to touch it and never place it near heat sources. Small precautions ensure great protection—family safety comes first.
