What are fire extinguishers

The classification defines the following types of fire extinguishers:

Powder. They are marked OP. The index indicates the mass of the charge (OP 5 - 5 kg, OP 4 - 4 kg). Powder extinguisher - universal device suitable for any type of fire - in electrical installations up to 1 kW, in oil storage facilities, in case of ignition of cars, in warehouses. The main extinguishing agent in a fire extinguisher is powder. According to the type of ejection, the jets are divided into gas generating (G), injection (Z), compressed air cylinder (B).
Carbon dioxide. They are labeled OU. The index also indicates the mass of the charge in the cylinder (OS 5 - 5 kg). A carbon dioxide fire extinguisher is used in electrical installations up to 1 kW in urban electric transport, on railway electric locomotives. The active substance is carbon dioxide under pressure, which varies depending on temperature. environment.
Air foam. ORP are marked. They have two types of active ingredients - chemical, foam consists of water and alkali, air-mechanical - from a foaming agent and water. Cannot be used in electrical installations. Use only for small fires of solids and flammable liquids.
self-acting modules. OSB marked. The active substance is a powder. Designed for fires of any class, they are also used in electrical installations up to 5 kW. A self-acting fire extinguisher is installed permanently in rooms with increased fire hazard, it is activated automatically, under the influence of smoke and flame. The OSB fire extinguisher has access to the most secluded corners of the room, inaccessible to people. Recommended for small areas.
Water. They are labeled OTV. The active ingredient is water. They are used for class A fires, and if there are additives in the water, then class B.

Powder and carbon dioxide differ in the volume of cylinders. They are portable - 1-10 liters and mobile - 20-100 liters. Mobile devices are often paired cylinders mounted on a special mobile cart.

What do the regulations say

The shelf life of a powder fire extinguisher is 10 years for a cylinder and 5 years for a charge. At the same time, cylinders installed at the factory, in public places, require an annual scheduled check, which is indicated by a special note in their passport. Specialists of the fire supervision service check the condition of the active substance by opening individual cylinders from the whole batch. According to its results, an assessment of the state is given and, if necessary, fire extinguishers are sent for recharging.
The shelf life of carbon dioxide type fire extinguishers is 10–15 years, depending on storage conditions. They also require an annual charge quality check. Specialists perform it by weighing the cylinder, determining the gas leakage and the condition of the shut-off valves. In production, a quarterly inspection is also carried out, which determines the installation site, appearance fire extinguishers. Every five years, the charge of a carbon dioxide fire extinguisher is renewed by completely discharging and cleaning from the remnants of the fire extinguishing agent. After that, a complete inspection of the integrity of the cylinder and a check of the tightness of the body are carried out.
Storage of water and foam type fire extinguishers - no more than 1 year, after which they must be replaced. This type of device cannot be recharged.

Most types are also better to replace right away than to recharge. The cost of charging is most often equal to the cost of a new fire extinguisher.

Car fire extinguisher - what is the expiration date?

The rules for operating a car require a fire extinguisher in its cabin or at least in the trunk.

The ideal option is powder compact models - OP 2 for 2 kg of active substance, which does not contradict the requirements of the Rules. For greater security, it is better to give preference to a metal case over a plastic one.

Free legal advice:

When buying, you need to pay attention to the seal, it must be intact, as well as the certificate and expiration date (5 years per charge). The advantages of powder models are a medium-strength jet, compactness, and low price. The disadvantage is that when used, the powder clogs the territory and surface.

If you choose a carbon dioxide fire extinguisher, then its volume should not be less than the powder one, and these are models OU 2 and OU 3, by 2 and 3 kg of charge, respectively. The advantage of gas-type models is a good pressure of the working jet and complete evaporation of the active substance. The disadvantage is the toxicity of the substance, which requires work with gloves or with a special gasket and a low range of the working jet - 50–70 degrees.

The expiration date of a car fire extinguisher corresponds to its type:

Powder - 10 years for a cylinder, 2 years for a charge;
Carbon dioxide - 15–20 years per cylinder, 5 years per charge.

How to store

According to the Code of Rules, a fire extinguisher is required to be carried in the cabin, mounted on a bracket with a lock and a lock. The best place for these purposes - the passenger door, from there the cylinder can be easily removed and used in case of fire.

If the car is stored in an unheated garage or on the street, then it is better to use a powder type fire extinguisher. His temperature regime storage is from -40 to +50 ˚С.

Free legal advice:

But in the summer, it is better to avoid direct sunlight on the cylinder, for which you should protect the car with a special shading, reflective curtain. In carbon dioxide models, as the ambient temperature rises, so does operating pressure inside the cylinder, which must be taken into account.

Can I store a fire extinguisher in the trunk

If there was no place for a fire extinguisher in the cabin, then it is better to fix it in the trunk than not to have it at all. In this case, recharging will need to be done more often, due to the direct influence of the environment on the cylinder, at least once a year.

Any deviation in the operating conditions of the car and storage of the fire extinguisher affects its shelf life. Of course, no one will determine the performance by eye. If a fire extinguisher in a car is required only to pass a technical inspection and throw dust in the eyes of traffic police, then it is only important to observe right choice models and warranty periods on the fire extinguisher passport. For those who care about their own safety, it is better to do device replacement and routine inspections more often.

What to do with an expired fire extinguisher

This question is asked by most motorists, having learned that the service life has come to an end.

Due to the extreme operating conditions of a car fire extinguisher, it rarely lends itself to recharging. Better buy new model, with high reliability guarantees. But the old one can be used as a training projectile.

Free legal advice:

It is no secret that few drivers have tried to use a fire extinguisher in practice. So there will be a chance to master this technique on your own, at the same time checking the veracity of the declared characteristics - the length and density of the jet, the operating time.

You can refill the fire extinguisher, using it as a stationary device in the garage, in the house, in the country. Ideally, it's best to take your end-of-life device to a recycling center if one is available in your area of residence.

How to find out the characteristics of a fire extinguisher yourself

All important parameters of the fire extinguisher are indicated in its passport, fixed directly on the cylinder. Mandatory of them are:

Factory number stamped directly on the passport;
manufacturer;
date of manufacture;
Working and test pressure;
The volume and weight of the balloon;
Factory OTK stamp.

When charging is performed, its date is affixed to the passport, and a control seal is installed on the cylinder.

Before buying a new fire extinguisher, it is better to immediately look at the device passport in order to determine for yourself how long it is guaranteed to serve you in the future. This knowledge will help to correctly determine the service life, recharge time, insuring against the questions of regulatory authorities - the fire safety department, traffic police services, and reduce the likelihood of fines.

Check frequency

There are two types of inspections of fire extinguishers: quarterly and annual.

Inspection of the availability and serviceability of carbon dioxide type fire extinguishing equipment is carried out once a year. By weighing the cylinder and calculating the flame-extinguishing mass, the suitability is checked.

Powder cylinders are controlled at least once every 5 years by selective withdrawal and opening. The district inspector conducts scheduled inspections, which include inspection of the body of fire extinguishers. In addition to monitoring the expiration date, the fireman checks the integrity of the seals, the condition of the metal coating, the functioning of the shut-off device and the lock.

Free legal advice:

If damage is detected, the cylinder is sent for MOT (maintenance).

During the quarterly inspection, the presence, location and appearance of fire fighting equipment are mainly controlled.

Organizations specializing in the maintenance of fire extinguishing equipment perform the following types of work:

inspect the hull and trigger devices;
check with instruments;
perform performance tests;
reload;
repair worn parts.

Fire extinguishers for vehicles, regardless of type, are subject to annual inspection:

powder are diagnosed using indicators;
carbon dioxide - according to the results of weighing and calculating the mass of the extinguishing agent.

What to do when the expiration date has expired

All fire extinguishing cylinders must be recharged in a timely manner:

in case of using the funds;
if the leakage parameters of the composition exceed the permissible level;
during scheduled reloading.

Service life before recharging fire extinguishers:

carbon dioxide - 1 time in 5 years;
powder - 1 time in 5 years;
air-foam - 1 time per year;
water - 1 time per year.

Vehicle fire extinguishers installed outside the cab must be recharged once a year due to the direct influence of the environment on the body. Other transport fire extinguishers are subject to maintenance at least once every 2 years.

In reality, models with a foam or aerosol system do not recharge for various reasons:

design features and principles of operation of some models;
the cost of recharging will cost about the same as a new fire extinguisher.

End-of-life cylinders remain as training material or are scrapped. Water-based and foam-type fillers can be discharged into the production waste outlet by diluting with plenty of water.

Other types of extinguishing agents must be professionally removed from the hull. It is not allowed to drain them into drainage systems, since the composition has chemical elements that contribute to environmental pollution.

Therefore, in almost all cities there are points for receiving used fire extinguishing devices, where decommissioned cylinders should be handed over. There they are disassembled and sent for recycling.
