Are Vehicle Fire Extinguishers Afraid of High Temperatures?
2 Answers
Fire extinguishers cannot withstand high temperatures and may explode, so precautions are necessary. However, under normal conditions, they will not explode. Here are some relevant fire prevention tips: 1. Placement conditions for fire extinguishers: The location where the fire extinguisher is placed should be kept dry and well-ventilated to prevent the cylinder from becoming damp and corroding. It should also avoid direct sunlight and strong radiant heat to ensure the normal use of the fire extinguisher. 2. Placement of fire extinguishers: Vehicle fire extinguishers should be placed in an easily accessible location and checked regularly. Proper maintenance and management of fire extinguishers should be enhanced to ensure that every fire extinguisher can effectively extinguish fires when needed, quickly putting out initial fires to reduce casualties and material losses.
I've been driving long-distance for twenty years, and what I fear most in summer is the extreme heat inside the car. Car fire extinguishers are absolutely afraid of high temperatures. When the interior temperature reaches 60-70 degrees Celsius, the pressure tank of the extinguisher is prone to thermal expansion and contraction, leading to gas leakage or even explosion, which poses significant risks. Once on a scorching day, I saw a fire extinguisher in a car's trunk bulging and deformed—fortunately, it didn’t explode and cause injury. Powder fire extinguishers may also clump and fail under high temperatures, making them impossible to activate in emergencies. That’s why I always store my fire extinguisher under the seat in a cool spot, regularly check the pressure gauge, or opt for a water-based type that can withstand higher temperatures, ensuring it’s always ready and safe to use. Additionally, avoid placing it in direct sunlight, such as on the dashboard or under the rear windshield, as these areas heat up the fastest.
