Do you want to buy a kind of fire extinguisher at home?

1. What kind of fire can the extinguisher extinguish?

Each fire extinguisher, have their own third of an acre, it is impossible decathlon. The fires are classified as follows:

Class A fire: Solid material fire.

Class B fires: Liquid or meltable solid matter fires.

Class C fire: gas fire.

Class D fires: Metal fires.

Class E fire: live fire. The object is charged and fired.

Class F fires: Cooking items (such as animal and vegetable oils) inside a cooking appliance fire.

For this reason, all fire extinguishers are marked with the type of fire extinguishing. Such as ABC dry powder, this refers to the dry powder fire extinguisher that can destroy the ABC Type III fire; BC dry powder, this refers to the dry powder fire extinguisher that can destroy the BC type fire.

Therefore, you must first widen your eyes to see ABCDEF . Otherwise, although the price is cheap, it does not necessarily work when used.

2. What is the extinguisher extinguishing capacity?

Fire extinguishers produced by different employers have different components of fire extinguishing agents filled in them, or different filling quantities and different fire extinguishing capabilities. Of course, we must be careful that some bosses are not very red-hearted, but this fire-fighting ability must be marked on the fire extinguisher cylinder. Look carefully when you buy it.

The specific fire-fighting capabilities are identified in front of the type of fire, such as 3A , 21B, etc. State regulations, we used ABC dry powder fire extinguishers, fire level 1 kilos is 1A, 4 kilos is 2A, 6 kilos is 3A, 8 kilos. 4A is, for a minimum level of oil fire is off 21B .

3. What is the protection distance and protection scope of the fire extinguisher?

This aspect is to be calculated. The detailed and detailed recommendations are based on the "Code for the Design of Extinguisher Configurations for Buildings" and it is a national standard, GB 50140-2005 .

Usually, the fire extinguisher has a protection distance requirement between 9 and 25 meters . That is to say, where the fire extinguisher is fitted, you can see by drawing a circle with a radius of 9-25 meters .

At the same time, we must calculate the area of ​​fire extinguisher protection. The simple point we talked about is that the scope of protection for each A is 100 square meters in general places (smaller risk) , 75 square meters in moderately dangerous places , and 50 square meters in places with serious danger .

Many units cannot figure out how much to buy when buying a fire extinguisher. Basically, this protection scope can be easily calculated. For example, if you have an office building of 1,000 square meters, buying almost 4 kg of ABC dry powder ( Grade 2A ) 4-6 will be enough.

For a small cafe, a shop or a restaurant, there are four basic ones that can handle it. If it is stratified, there are basically two passes per floor .

4. How much is the fire extinguisher cost?

This is usually a bit different, but the difference is not great. Take the most commonly used ABC dry powder fire extinguisher as an example, generally 2 kg , about 40 yuan; 4 kg , about 70 yuan; 8 kg of about 100 yuan.

Some fire extinguisher surfaces are stainless steel, some are made into toy shapes, or the colors are different. They are a bit of cats and dogs. This may increase the cost, but it is not very meaningful for fire fighting.

5. What kind of fire extinguisher should I buy at home?

Home fires are generally Class A and Class D fires. Occasionally Class C and Class F fires will occur . Generally, ABC dry powder fire extinguishers are used. To meet the fire extinguishing needs, 2 kg or 4 kg can be selected .

It should be noted that the dry powder fire extinguisher will cause pollution on the fire site after it is extinguished, and it will be difficult to clean the electrical product fire after using a dry powder fire extinguisher.

For these reasons, the new water-based fire extinguisher (water-based spray) or carbon dioxide extinguisher is also recommended.

Vehicle fire extinguisher is recommended to configure 4 kg ABC dry powder, too small will not destroy the fire.

6. Fire extinguisher maintenance

Of course, fire extinguishers are often repaired. To see if it is not gasless, is it because the pipe is rotten? Has it hit a pit? This should be done frequently. In addition, there must be maintenance. Normally, after the fire extinguisher is delivered, the dry powder is to be repaired for the first time in 5 years, and then every 2 years, and it must be scrapped after 10 years.

Of course, the same goes for other fire extinguishers. Only the time limit is not the same.

7 , pay attention to

Fire extinguishers have very limited ability to extinguish fire. Moreover, firefighting is also a technical activity. It is definitely not a good job, and the fire is not abolished.

So, we want to extinguish fire and want to be a hero. That's right. At the same time, we must make the following preparations: First, while extinguishing fire, other people who do not extinguish fire should immediately retreat and do not look around; second, they must leave a posterior path when fighting fires. Once it feels bad, it does not matter. Under the fire extinguisher, he ran away and his life was always the first, not one.
