A car fire extinguisher is one of the items that must be tested in the annual inspection of the car. However, many drivers usually do not pay attention to the use of car fire extinguishers, and even do not pay attention to the use of car fire extinguishers. In this article, we will briefly introduce the car fire extinguisher.

Types of car fire extinguishers

A car fire extinguisher is specially used for automobile fire extinguishing, including two types: non-pressure suspension ultra-fine dry powder automatic fire extinguishing equipment and miniature car with storage pressure suspension ultra-fine dry powder automatic fire extinguishing equipment. At present, portable fire extinguishers are mostly used for automotive firefighting. The main vehicle fire extinguishers on the market are dry powder fire extinguishers, ultra-fine dry powder fire extinguishers, carbon dioxide fire extinguishers, and water-based fire extinguishers.

The fire extinguishing principle of the vehicle fire extinguisher

The mechanism of carbon dioxide fire extinguishers is asphyxiation, that is, by reducing the concentration of oxygen in the air around the combustion material to extinguish the fire. Carbon dioxide as a fire extinguishing agent has good insulation properties. However, its disadvantages are: high fire extinguishing concentration, low fire extinguishing level, should be used in a relatively closed empty room, its poor resistance to re-ignition, at the same time, carbon dioxide is a medium toxic substance, the improper operation is easy to cause harm to humans. When the concentration of carbon dioxide reaches 7% to 9%, it will lead to breathing difficulties, vomiting, numbness, and delirium. When the concentration reaches 10%, a person will lose consciousness if he or she stays in this environment for one minute. Therefore, when using carbon dioxide fire extinguishers must pay attention to safety.

Water film foam fire extinguisher fire extinguishing mechanism is cooling isolation, fire extinguishing level is high so that the loss of water damage is small, neither the secondary pollution of dry powder nor the toxicity of carbon dioxide. However, one of the biggest disadvantages of the current domestic production of water foam fire extinguishing agents is the poor stability after dilution, which can not be stored for a long time. As a practical fire extinguishing agent, storage stability is one of its most important performance indicators. At the same time, in comparison, the price of water-based film foam fire extinguishers is also high.

These are the four most common types of automotive fire extinguishers. These fire extinguishers have their own advantages and disadvantages, but will not affect their overall function and role. Consumers, can understand the annual audit requirements and related knowledge when choosing to buy, and then follow the guidance of professionals before purchasing for better use in the event of an accident.
