Car fire extinguishers also have shelf life, do you know?
In recent years, an increasing number of private car owners have become more aware of safety measures, such as installing onboard fire extinguishers for emergencies. However, according to a recent investigation by a reporter, many vehicles are still unable to be saved in the initial stages of a fire—not because they lack fire extinguishers, but because the devices fail when needed most.
One such incident occurred on Taishan Road in Huanggu District, where a sedan caught fire unexpectedly. Mr. Liu was driving to pick up his children when he noticed something wrong: the dashboard suddenly emitted black smoke, and a strong burning smell filled the air. A short circuit had caused a fire under the hood.
Quickly, Mr. Liu rushed to the trunk and grabbed the fire extinguisher. He managed to spray it a few times before realizing that the pressure was extremely low. He then called 119 to report the fire. Unfortunately, the extinguisher wasn't effective due to long-term neglect—no maintenance had been done since it was first installed, and the pressure had dropped significantly.
Mr. Liu now urges other drivers to pay more attention to their vehicle’s fire extinguishers. Though they may take up space in the trunk and slightly increase fuel consumption, they can be life-saving tools during emergencies. He suggests that car owners should regularly check their fire extinguishers and ensure they are in good working condition.
A recent survey conducted by the reporter found that many drivers are unaware that fire extinguishers have expiration dates. When asked, most people believed that if a fire extinguisher had never been used, it would always work. However, in reality, expired extinguishers often fail to function properly during critical moments, which can lead to serious consequences.
Experts warn that fire extinguishers require regular maintenance. Inside, they contain chemical substances that can degrade over time. If not maintained, the cylinder may corrode and even explode when used. Expiration is a major risk factor, as old extinguishers may not release properly when needed.
To check if a fire extinguisher is still functional, users should look at the date on the label and the pressure gauge. The needle should be in the green zone, indicating normal pressure. If it's in the red, the extinguisher needs to be repaired or replaced. Generally, fire extinguishers should be inspected after five years from the manufacturing date and every two years thereafter.
Moreover, in humid environments, fire extinguishers are more prone to moisture damage and loss of effectiveness. It's essential to perform regular checks. Fire extinguishers also have a retirement period: CO2 models typically last 10 years, while water-based ones only last six. After expiration, they should not be discarded carelessly but instead handed over to environmental or fire departments for proper disposal.
In conclusion, while fire extinguishers may seem like a small addition to a car, they play a crucial role in emergency situations. Regular maintenance and awareness of their lifespan can make all the difference between saving a vehicle and losing it completely.
