Basic knowledge of spring safety and fire prevention

The climate in spring is unstable, windy, and dry; there are many activities and frequent personnel activities, which are easy to cause fires. Pay more attention to fire prevention.

  Home fire protection

The causes of domestic fires are mostly careless use of domestic fires and household appliances or improper use of flammable and combustible materials. Seven notes for home fire protection:
1. Don't stay in bed to smoke, don't throw cigarette butts and matches; educate children not to play with fire
2. Liquor, paper, curtains and other flammable and combustible materials should keep a sufficient safe distance from the fire source.
3. Use all kinds of household appliances correctly, choose a safe and reliable power switch, and turn off the power before going out.
4. Do not answer the phone and do other housework while ironing clothes. Do not leave home when using liquefied gas, coal gas, or natural gas. After use, turn off the switch, and do not allow children to randomly disturb the gas facility to avoid gas leakage.
5. Properly keep flammable and combustible materials in the home to ensure the smooth flow of public passages and safety exits.
6. Don't bury, press, circle or occupy the fire protection facilities, but keep the fire protection facilities intact. Equip the necessary fire extinguishing equipment in the home and learn to use it correctly.
7. If the house is equipped with anti-theft nets and other facilities, escape exits should be reserved.

Electrical fire protection

Electrical fire protection must first select safe and qualified products, and use and operate correctly.

Causes of electrical fires:

1. Electrical short circuit: due to the damage of the line insulation layer, the short circuit of the wire generates a strong spark, causing a fire of combustibles.
2. Overload: As the power consumption of the electrical appliances turned on at the same time exceeds the safety value of the wire, the wire will heat up and cause a fire.
3. Electric leakage: Electric leakage will generate sparks and cause fire.
4. Poor line contact, heat up or sparking, causing fire. School Fire Prevention School is a place where students gather. Once a fire occurs, the hazard is very serious.

How to use all kinds of fire extinguishers

1. Foam fire extinguishers are used to extinguish fires caused by gasoline, kerosene, diesel and wood. The method of use is: hold the lifting ring in one hand, hold the bottom in one hand, turn the fire extinguisher upside down and shake it a few times, the foam will spray out. Note that the fire extinguisher should not spray on people, do not open the cylinder cover, and do not spray with water.

2. Dry powder fire extinguisher is a general fire extinguishing equipment used to extinguish the initial fire of petroleum and its products, combustible gas and electrical appliances. When in use, hold the nozzle with one hand, aim at the fire source, and lift the pull ring with one hand, it will spray thick cloud-like powder mist, cover the burning area, and put out the fire. Dry powder fire extinguishers should pay attention to prevent moisture and sunlight, and strictly prevent air leakage. Check every six months. After each use, refill and inflate.

3.1211 fire extinguisher is a new type of pressure gas fire extinguisher. Its fire extinguishing agent has high fire extinguishing performance, low toxicity, low corrosion, and is not easy to deteriorate. It does not leave traces after fire extinguishing. It is used to extinguish fire oil, electrical appliances, precision instruments, meters, books Documents and other fires. When using it, first pull out the safety pin, hold the pressure lever with one hand, and align the nozzle with the root of the fire source with one hand, the pressure bar will open, sweep left and right, and advance quickly. The 1211 fire extinguisher should be placed in a ventilated and dry place, and the total weight should be checked every six months. If the weight drops by one-tenth, it must be filled and inflated.

4. Carbon tetrachloride fire extinguishers are mainly used to extinguish equipment fires. Never use it for fires caused by metallic potassium, sodium, magnesium, aluminum powder and calcium carbide.

   prompt:
In the event of electrical fire or electric shock, emergency rescue shall be carried out immediately: (1) turn off the power switch and cut off the power; (2) use fine soil, sand, carbon tetrachloride or 1211 fire extinguisher to extinguish the fire. To avoid electric shock.
