Where should I put the fire extinguisher?

Dry, cool and well ventilated, do not be near high temperature or places that may be exposed to sunlight. If it is a public place or a crowded place, it should be placed under the fire hydrant box. If it is a car, it should be placed in a convenient position in the trunk to facilitate fire fighting and first aid (put it in the trunk, if the engine is on fire, it can't be opened and taken).

If it is for home use, it should be put in a convenient place. If there are children, hide them to avoid accidental injury or damage by them.

In addition: different types of fire extinguishers are placed in different locations. All the above situations are based on dry powder fire extinguishers.

Carbon dioxide fire extinguishers should be placed in weak current computer rooms and other places. Because carbon dioxide is a toxic gas, it is mainly used in electrical fires.

Water-based fire extinguishers are mainly used to extinguish fires in kitchens. Foam extinguisher is used for liquid oil fires.

Fire extinguisher is a portable fire extinguisher with simple structure and convenient operation, and it is an important fire extinguishing equipment to remedy the initial fire. Fire extinguishers can be divided into portable and cart-type according to the moving mode, and can be divided into foam dry powder fire extinguishers and carbon dioxide fire extinguishers according to the different filling fire extinguishing agents.

The Code for Maintenance and Use of Fire Fighting Equipment requires managers to use and maintain fire fighting equipment correctly to deal with fire hazards.

There are many fire-fighting equipment, such as automatic alarm fire alarm system, fire hydrant, fire extinguisher and so on.

How to use:

When extinguishing the fire, lift the fire extinguisher about 5 meters away from the fire source, put it down, then pull out the safety pin, hold the handle at the root of the horn with one hand, and hold the closed handle tightly with the other hand to spray at the fire source.

For carbon dioxide fire extinguishers without spray hose, the horn should be placed at 70 ~ 90 degrees with the upper plate. When in use, you can't directly grasp the outer wall of the horn and the metal connecting pipe by hand to avoid frostbite.

When putting out fire, users should spray carbon dioxide and fire extinguishing agent from near to far when combustible liquid is burning. If flammable liquid burns in the container, the fire extinguisher should aim at the flame in the container and not spray it on the surface of the burning liquid.

Cart-type carbon dioxide fire extinguishers are generally operated by two people. When in use, it is pushed to a distance of 0/0 meter from combustible/kloc-. One person quickly took off the horn, opened the injection hose, and the other person quickly turned the handwheel clockwise to open it to the maximum position. The fire extinguishing method is the same as the hand lifting method. When used outdoors, it should be sprayed in the upwind direction, and used in narrow spaces indoors. People should put out the flames and leave as soon as possible to avoid suffocation and poisoning.

Check the weight of fire extinguishers twice every six months, and check by weighing method. When it is found that the weight of fire extinguishing agent is reduced by more than 10% or the bottom is in the green area, the pressure gauge indicates that it must be refilled.

Fire extinguishers should be stored in a cool, dry and ventilated place, and the ambient temperature is preferably between 5℃ and 45℃. After each use, it should be sent to the maintenance unit for hydrostatic test every five years. 12 1l fire extinguishers are suitable for the initial fire of oil, gas and electrical equipment. There are also portable and cart-type fire extinguishers, and the use method is basically the same as that of carbon dioxide fire extinguishers. Third, the maintenance of fire extinguishers.

Fire extinguishers should be stored in a cool, dry and ventilated place, and the ambient temperature is preferably between 5℃ and 45℃. Check dry powder for caking and gas leakage every six months. If it is found that the weight of the fire extinguisher is reduced by more than 10% or the pressure gauge indicates that it is lower than the green area, it must be refilled.

Once the fire extinguisher is turned on, it must be refilled, and the water pressure test shall be carried out before each filling or three years after leaving the factory. The maintenance of fire extinguishers should be the responsibility of professionals.
