Terms of use of fire extinguisher. How to use the fire extinguisher

The rules for using a fire extinguisher should be known to everyone, since we can all end up in an unexpected and dangerous situation. In principle, the operation of the presented device is not heavy, but it has its own peculiarities. For example, you should know in which cases and what kind of fire extinguisher should be used. First, let's look at the types of devices presented.

Types of fire extinguishers

So, there are many criteria for classification:

1. The dimensions of the device are manual, industrial and mobile. They differ in the volume of the cylinder: from 2 to 10 liters and more.
2. According to the type of start-up device, the fire extinguisher can be pistol or valve. There are also devices capable of operating from a constant source of pressure.
3. By the substance that is contained inside the vessel, there are powder, water, gas fire extinguishers.

Principles of using the device

Before using a fire extinguisher, you should definitely understand the principles of its use. For example, containers with water inside can be used to extinguish solids that burn easily. However, the liquid may contain additional components. They give the opportunity to extinguish and liquid combustible substances. The rules for using a fire extinguisher of the type presented are fairly simple: they can only be operated in the listed situations. The fact is that water is able to enter into chemical reactions with other elements and form substances that are dangerous to health.

The rules for using a fire extinguisher with gaseous filler provide for compliance with a single safety rule: they can not be touched by the tube, since you can easily get frostbite. However, such a device would be useless in cases where those items that can blaze without access to oxygen are burning.

In order to extinguish a chemical substance or an air-mechanical fire the foam extinguisher is most suitable. However, it is not recommended to use it in case the electrical equipment burns. Naturally, you can not use a device to extinguish those substances that can react with water.

Features of the use of extinguisher OS

In principle, it is not difficult to operate such a device. You just have to follow certain instructions. The rules for the use of the OU fire extinguisher provide for such a step-by-step action:

1. First, you should approach the source of fire at a distance of at least 2-3 meters.
2. Now point the bell exactly toward the flame and hold it as firmly as possible.
3. In order for the fire extinguisher to function, it is necessary to break the seal and the check, which protects the device from automatic triggering.
4. Now you can open the lock or press the handle. Here everything depends on the structure of the device.
5. After the fire is eliminated, you need to release the handle or tighten the valve.

Reuse of such a device is possible only after a new refueling of the cylinder with carbon dioxide.

Features of the use of powder devices

Before using the extinguisher of the presented type, it is necessary to familiarize yourself with the instruction manual:

• Take the device and go to the fire. In this case, the distance to the flame should not be less than 2 meters.
• In order for the fire extinguisher to become operational, remove the seal and the protective pin from it.
• Now accurately point the nozzle to the fire, do not touch it, so as not to get injured (frostbite).
• Note that keep the device firmly so that the pressure of the contents of the cylinder does not lead to the loss of fire extinguisher from the hands.
• Now click on the lever or unscrew the valve. Close or release the locking mechanism only after the fire has been eliminated.
• If there are other sources of flame, the device can be re-applied.

When can I not use a powder device?

There are situations in which the use of this device is unacceptable. The rules for the use of fire extinguishers OP provide for their inability to operate in such cases:

• If you need to extinguish those things that can burn without the help of oxygen;
• If the electrical network or appliance has ignited;
• To extinguish any antiquarian values, paintings or books (they may be damaged in the process of eliminating fire).

Some of the nuances of using and storing a fire extinguisher

You can determine a sufficiently large number of features of the application of the device. For example, if you extinguish flames with several types of fire extinguishers, then you should not direct them to each other. In any situation, it is necessary to observe a certain distance from the flame during extinguishing. Especially this applies to burning chemicals or agents that flash easily, as well as electrical appliances that are under tension.

The rules for using a fire extinguisher provide for a certain time of continuous operation of the device, which ranges from 2 to 14 seconds. The period is indicated on the label with the information. During the extinguishing the balloon must be kept strictly vertically. Otherwise, you will not be able to use all the inner material of the vessel.

The use of a powder fire extinguisher is limited in the room, as it causes severe dustiness. The same applies to carbon dioxide devices, because they are able to reduce and so a small amount of oxygen in the building. After the operation of the device, it must be sent for recharging, even if there is still a charge inside.

What can not be done during operation and storage of the device:

• Do not allow any damage or dents to appear on the body of the device;
• You can not beat the balloon;
• Do not use a fire extinguisher if it has a manufacturing fault or a malfunction of the locking mechanism;
• Do not recharge or disassemble the device by yourself;
• After use, the unsuitable extinguisher must be disposed of;
• You can not use the device for those purposes that are not related to extinguishing the fire;
• During the elimination of the source of ignition, one should not direct it towards people.
