Whether it is dangerous to keep a fire extinguisher in the car during high summer temperatures depends on local temperature conditions and maintenance. Generally, it will not explode. There are many types of fire extinguishers, and most vehicle-mounted fire extinguishers are dry powder extinguishers. Theoretically, dry powder extinguishers can be stored at temperatures between -20°C and 55°C, so they will not explode when kept in a car under normal conditions. Here are some items you should avoid leaving in the car during summer: Lighters: Small and easy to forget, yet highly dangerous. They contain liquid butane, and exposure to sunlight can increase internal pressure, leading to explosions. Bottled water: If left in a sun-exposed car for a certain period, it can release harmful substances. Continued consumption may not only fail to quench thirst but also affect health and cause discomfort. Glasses: Especially reading glasses, as their convex lenses can focus sunlight, potentially causing a fire. Perfume (in glass bottles): Perfume emits flammable gases when it evaporates. The critical packaging point is 49°C. Tests show that on a summer noon, without any shade, the car temperature can reach 65°C in just 15 minutes of sunlight exposure, which can easily trigger an explosion.
