What type of fire extinguisher is best for cars?
2 Answers
Dry powder fire extinguishers or water-based fire extinguishers are recommended for cars. Below is an introduction to these two types of fire extinguishers: 1. Dry powder fire extinguishers extinguish fires quickly and are cost-effective, but they are polluting and corrosive. The fire extinguishing mechanism of dry powder fire extinguishers is chemical inhibition, which interrupts the chain reaction of combustion. They have a high fire extinguishing rating, are multifunctional, extinguish fires rapidly, and possess electrical insulation properties and good low-temperature performance. 2. Water-based fire extinguishers cannot extinguish Class D metal fires but can extinguish other types of flames. They are non-polluting, harmless to humans, and most effective at extinguishing Class B liquid fires, making them particularly suitable for engine and car fires. However, they are difficult to store and expensive.
Powder fire extinguishers are the most reliable choice for cars. They are particularly effective against vehicle fires, whether it's an electrical circuit fire or a fuel line fire. Remember to buy a small car fire extinguisher weighing 1 to 2 kilograms, as larger ones take up too much storage space. I keep a powder extinguisher in my car because many professional auto repair shops recommend it—not only does it extinguish fires quickly, but it's also affordable, available for just a few dozen yuan at ordinary auto parts stores. Remember to check the pressure gauge every six months, and replace it immediately if the pressure is insufficient. Also, never buy those water-based extinguishers just to save money—they're completely useless for electrical fires in cars.
