Car fire extinguishers also have shelf life, do you know?

Nowadays, more and more private car owners are beginning to raise their awareness of safety, such as installing on-board fire extinguishers in vehicles for emergency use. However, the reporter’s investigation found that many cars could not be saved for the first time in the event of a fire, not because there was no onboard fire extinguisher, but because the fire extinguisher “strikes”...

Car spontaneous combustion

The fire extinguisher sprayed twice and it was boring...

A spontaneous sedan incident occurred on Taishan Road in Huanggu District.

Mr. Liu drove to the school to pick up the children. The car just stopped. He found that the car was not quite right: the instrument panel suddenly emitted black smoke, and a pungent scorching smell came over. The wire at the front cover was short-circuited. on fire.

Mr. Liu quickly rushed to the trunk and took out the fire extinguisher. Only two or three shots of the extinguisher had been used. Liu quickly reported 119 fire.

Originally Mr. Liu’s car fire extinguishers were brought in when they were first bought. They were not used for many years and no maintenance had been done. The pressure was obviously insufficient, and they encountered a sudden lack of energy. Mr. Liu also wanted to put forward a proposal to the majority of riders through this newspaper: Car fire extinguishers can be sent to large-scale use at key moments, and must pay attention to repairs and maintenance. Although it occupies a lot of places in the trunk, it also increases the weight of the car and may cost some oil, but at a critical moment, it can avoid the fate of the car.

Survey by reporter

Most riders do not know that the fire extinguisher will expire

In recent days, the reporter interviewed many citizens randomly. No one actually answered such questions accurately. Respondent riders all agreed that "Since the fire extinguisher has never been used at one time, how could it fail?"

"A lot of vehicles are not equipped with fire extinguishers. Some of them are equipped with but failed to fully function at the critical moment because of the failure of fire extinguishers." In the event of a fire, expired fire extinguishers cannot spray bubbles and delay the best time for fire fighting. Probably because of the lack of timely firefighting and heavy losses.

Expert reminds

Fire extinguishers also have to regularly "check"

It is understood that the interior of the fire extinguisher is full of chemical substances. If it is undermaintained or rusted for a long time, the bottle body will be corroded. When it is actually used, the bottle body may explode because it cannot withstand the ejected pressure. In particular, extinguishers such as carbon dioxide, foam, and dry powder have hidden dangers.

"The greatest danger of an expired fire extinguisher is that it cannot be ejected normally when it needs to be extinguished." Fire extinguishers have potential safety hazards when they expire, and they must be promptly replaced and improved in order to avoid chemical failure or agglomeration.

"In the warranty period, residents determine whether the fire extinguisher is effective, first depends on the date of extinguishing the fire extinguisher; Second, look at the fire extinguisher pressure gauge. To see if the fire extinguisher pressure indicator pointer is in the green area, green indicates that the internal working pressure of the fire extinguisher is normal; yellow indicates The pressure is too high; the red indicates that the pressure is too low, and this situation requires the stamping of the repair shop."

Under normal circumstances, the fire extinguisher will be repaired for the first time after 5 years from the factory and every two years thereafter. However, if the fire extinguisher is in a relatively humid environment, it is prone to dampness and clumps and loses its efficacy, so regular medical examinations are particularly important. In addition, fire extinguishers also have a retirement period. In general, the maximum scrapping period for portable CO2 fire extinguishers and cart-style CO2 extinguishers is 10 years. The retirement period for portable water-based fire extinguishers and cart-type water-based fire extinguishers is only 6 years. The fire department recommends that for reasons of environmental protection, fire extinguishers should not be discarded after they expire and should be disposed of by the environmental protection department, fire department, or fire equipment store.
