Will a water-based fire extinguisher explode in a car during high summer temperatures?

Water-based fire extinguishers placed in cars will not explode during high summer temperatures. Water-based fire extinguishers primarily exist in liquid form, hence the name "water-based" fire extinguishers. Additionally, water-based fire extinguishers are designed to withstand high temperatures, capable of enduring around 100 degrees Celsius, so they generally will not explode. Functions of water-based fire extinguishers: Water-based (water mist) fire extinguishers, when discharged, form a fine mist that instantly evaporates a significant amount of heat from the fire scene, rapidly lowering the temperature and suppressing thermal radiation. The surfactants quickly form a water film on the surface of combustible materials, isolating oxygen and providing both cooling and isolation effects, thereby quickly extinguishing the fire. Precautions for vehicle fire extinguishers: Purchase from reputable fire equipment stores and verify their business license and product certification before buying. Also, carefully check the expiration date of the fire extinguisher. When selecting a vehicle fire extinguisher, in addition to paying attention to its appearance, car owners should request the product certification, quality guarantee, and user manual from the seller, and obtain an invoice for future reference in case of issues. The fire extinguisher should be placed in a dry, ventilated, and easily accessible area, away from open flames, high temperatures, and greasy areas. Regularly check if the safety pin is intact, if the cylinder is deformed or corroded, and if the nozzle is clogged with grease.

As a veteran driver with over a decade of experience, I always keep a water-based fire extinguisher in my car. During summer, cabin temperatures can reach 60-70°C, but extinguishers from reputable manufacturers come with pressure relief valves that automatically release pressure when temperatures get too high. My advice is to avoid leaving it exposed under the windshield – the trunk's shaded area is the safest spot. Check the pressure gauge every six months; as long as the needle stays in the green zone, there's nothing to worry about. These extinguishers mainly contain water and flame retardants, making them less sensitive than gas canisters. In all my years of long-distance driving, I've never encountered any issues.

I've researched automotive safety equipment, and water-based fire extinguishers have an extremely low probability of exploding under high temperatures. National standards require such products to pass an 85°C environmental test, with canister materials capable of withstanding thermal expansion. However, three points should be noted: purchase certified products with 3C authentication, avoid storing them in exposed positions like the dashboard, and regularly check for canister deformation or bulging. In summer, try to park in shaded areas, and if the interior temperature exceeds 60°C, it's best to remove the extinguisher to cool it down. After all, safety is no trivial matter—prevention is always better than regret after an incident.

Last week, I consulted a friend from the fire department, and their firefighting training equipment is stored outdoors year-round. Water-based fire extinguishers are designed with a safety margin for internal pressure, with a normal operating range of 50-60°C. However, dashboard temperatures can soar to 80°C in summer, and prolonged exposure to direct sunlight may damage the sealing ring, leading to leakage. My friend recommended storing it in the trunk storage compartment and covering it with a sunshade cloth. Also, pay attention to the expiration date—expired fire extinguishers may experience internal corrosion, reducing pressure-bearing capacity and potentially increasing risks.
