Three Misunderstandings of Vehicle Fire Extinguisher Use

40% of private cars are not equipped with fire extinguishers. The Beijing new car licenses and inspections require fire extinguishers. However, in the investigation, the reporter found that 40% of private car owners did not provide fire extinguishers for the car. "When I bought a car, I took the 4S shop agent to handle the formalities. They temporarily found a fire extinguisher in the car and later took it away." Private car owner Ms. Liu said that when she purchased the car, the 4S shop was not free. She provided on-board fire extinguishers and she did not pay extra for fire extinguishers. The owners of Mr. Li and Mr. Chen also stated that they used the fire extinguisher to “pass through” when they examined the car.

Why don't you have a fire extinguisher in your car? Ms. Liu believes that self-ignition is often related to the neglect of maintenance of "old-age cars" and the private transformation of vehicles. They are buying new cars and are diligent in maintenance. They will not spontaneously ignite. Mr. Li stressed that the chance of spontaneous combustion of the vehicle is very small. Even if a fire extinguisher is equipped, it is not necessarily useful. It is better to buy a “self-ignition insurance”.

Half of the owner of the fire extinguisher did not know that there was a shelf life survey. Half of the car owners who provided the fire extinguisher said that it was not clear that the fire extinguisher had a shelf life. “Is the fire extinguisher not in use and will it expire?” Mr. Ding, the owner of the vehicle, questioned that the fire extinguisher is usually placed in the trunk with very few opportunities to use it. Therefore, it has been stored for a long time. A lot of car owners thought.

Jin Xuan, the Xuanwu District Fire Fighting Brigade, pointed out that most vehicle-mounted fire extinguishers are dry powder fire extinguishers. They are powered by liquid carbon dioxide or nitrogen, which drives the dry powder fire extinguishing agent to eject and extinguish the fire. Its shelf life is one year. Every other year, the owner should check whether the gas in the fire extinguisher is leaking and whether the dry powder is agglomerated. In this way, the fire extinguisher can be inflated or replaced with dry powder. Otherwise, the fire extinguisher that expires may not spray dry powder, or the time for injection is greatly shortened. , directly affect the normal use.

There are three misunderstandings in the use of fire extinguishers. Only a few private car owners stated that they had used fire extinguishers when they participated in fire training. The remaining 90% of owners said that it is not clear how to properly use fire extinguishers. Jin Hao said that the owner of the fire extinguisher should avoid the following three errors.

Fire-extinguishing fire extinguishers can only be used to extinguish primary fires. To be effective, the timing must be grasped. This means that owners should use fire extinguishers when they find that the car has a strange smell of smoke. Otherwise, they will be rescued after seeing the open flame, even if they use it. Larger fire extinguishers have also become a "glass of water." The importance of fire-fighting depends on the size of the fire extinguisher itself.

When using a fire extinguisher, the owner of a fire extinguisher should not spray it on the surface of the flame, but should aim at the root of the flame and confirm that the flame has been extinguished before the fire extinguisher can be removed.

For someone who thinks that opening the hood will allow air to enter and make the fire more prosperous, Jin Hao said that even if the hood is not opened, the air is still connected, and when the hood is opened in case of fire, the fire point is spotted for the first time. important.
