Will a Car Fire Extinguisher Explode If Left in the Vehicle?

Car fire extinguishers will not explode if left in the vehicle. Car fire extinguishers are portable firefighting equipment containing chemical substances inside. In case of a fire caused by high temperatures, vehicle malfunctions, or short circuits, the extinguisher can be used to put out the fire, ensuring personal safety and reducing losses. How to use a car fire extinguisher: 1. Pick up the extinguisher and position yourself upwind; 2. Shake the extinguisher upside down several times to loosen the dry powder inside; 3. Remove the safety pin, hold the handle with your left hand, and grip the nozzle with your right hand, then invert and hold the extinguisher upright; 4. Aim the nozzle at the base of the flames and spray.
Speaking about whether car fire extinguishers can explode in vehicles, I've actually researched this. Generally speaking, certified car fire extinguishers are designed with vehicle environments in mind, equipped with pressure relief valves to maintain safety, so they won't explode under normal circumstances. Many car owners worry about summer heat causing explosions, but experimental data shows that even when cabin temperatures reach around 60°C, the internal pressure remains within safe limits without sudden ruptures. However, risks may arise with poor-quality, expired, or physically damaged extinguishers - like those frequently crushed under rear seats. My recommendation is to choose CCC-certified products (avoid cheap roadside stall purchases), regularly inspect the canister for deformations or leaks, and store it in a shaded side area of the trunk rather than on the dashboard under direct sunlight. This approach ensures both safety and readiness for fire emergencies.
