Why do you need a fire extinguisher?

Many of us only know about a fire extinguisher that its place is in the far corner on the wall or in the trunk of a car. We also know that with the help of this balloon it is possible to extinguish the fire. But in order to use a fire extinguisher in a critical situation, this knowledge is not enough.

Despite the fact that the legislation does not prescribe the owners of residential buildings to equip them with appropriate fire extinguishers, their presence is still encouraged. This is due to the fact that not all residential buildings are timely replaced with electrical wiring, its check.

Also, some irresponsible citizens use independently prepared devices that work from the network. All this is fraught with fires, as a result of which you can lose all your property.

What is a Fire Extinguisher

A fire extinguisher is a portable, mobile, or stationary device that is designed to extinguish a fire by releasing a fire extinguishing agent, with a manual method of activating this device and manually controlling a stream of a fire extinguishing agent.

How To Use Fire Extinguisher

How to use a carbon dioxide fire extinguisher correctly and what it is for

Car owners are faced with this type of fire extinguishers most often – such a cylinder must be in the trunk of every car. It is forbidden to use such a device to eliminate the ignition of substances that burn in the absence of oxygen. In addition, it is strictly forbidden to extinguish a burning person with carbon dioxide.

Instructions for the use of a carbon dioxide fire extinguisher:

  • Break the seal
  • Pull out the check
  • Direct the bell to the fire site
  • Push the lever

How to Use and Where to Use a Foam Air Extinguisher

This type of device is used to extinguish solid materials, flammable and flammable liquids. With the help of such fire extinguishers, it is forbidden to extinguish alkali metals, materials that do not need oxygen for combustion, electrical appliances included in the network.

The peculiarity of the foam-air fire extinguisher is the presence of a nozzle and a can of gas, which serves as a source of excess pressure. Under the influence of this gas, the foaming agent in the cylinder rushes towards the nozzle. There it mixes with the air. The result is foam, with which the fire is poured.

Operating instructions for the foam-air fire extinguisher:

  • Break the seal
  • Pull out the check
  • Direct the nozzle towards the fire
  • Press the lever (or button) of the additional can
  • Press the main lever

How to use a dry powder fire extinguisher

Powder fire extinguishers are useful for the fire of solids, electrical devices, and installations with an operating voltage of up to 1000 V. Liquid and gas also cannot be extinguished without such a device.

There are few contraindications to the use of such fire extinguishers: it is forbidden to use them to extinguish substances that burn in the absence of oxygen. There are two types of dry powder fire extinguishers: pumped in and with a built-in pressure source.

The advantage of both types is the ability to dosed powder consumption and control the intensity of the jet. In the case of a pumped-in fire extinguisher, the powder contained in the cylinder is fed into the hose under the action of the gas. Once on the fire site, it isolates the source of ignition from oxygen and combustion stops.

Instructions for using the uploaded powder fire extinguisher:

  • Aim the hose nozzle at the fire
  • Break the seal
  • Pull out the check
  • Push the lever

A feature of the second type of dry powder fire extinguisher is the presence of an additional gas cylinder, which creates pressure. By opening the locking mechanism, the plug between the two cylinders is removed and the gas pushes the powder towards the nozzle.

Instructions for using a dry powder fire extinguisher with a built-in pressure source:

  • Break the seal
  • Pull out the check
  • Raise the main lever to failure
  • Hit the button on the gas cylinder
  • Aim the hose nozzle at the fire
  • Press the main lever

It is important to know what fire extinguishers are and how to use them. But we must not forget that such devices become unusable over time. Therefore, you need to monitor the expiration dates indicated on the cylinders and change them periodically.

The buy-and-forget principle will play a cruel joke in this case. At a critical moment, a working fire extinguisher cannot be at hand. In this case, the damage to property will definitely exceed the price of a new device several times over.

It is not necessary to replace the entire cylinder. It can be rinsed and recharged with a fresh portion of the active ingredient. It is cheaper but more labor-intensive. Which method is optimal is up to you.

Summary

If a fire breaks out, promptly call the fire department. But before help arrives, it is important to follow independently, otherwise, firefighters may simply not be in time. It is necessary to slightly open the place from where the flame is examined and insert a fire extinguisher into the slot and act according to its intended purpose. In any case, you must have a fire extinguisher with you. You never know what will happen today.
