Which gas mask will protect against everything? Will the gas mask help in case of fire? Answers to 5 popular questions about gas masks

What is a gas mask - everyone knows. For what it is needed, is also not a secret. And, despite the fact that at present, relatively peaceful time, the population is not exposed to mass infections and attacks of chemical and bacteriological weapons, gas masks are in great demand - the risk of getting into an emergency situation always remains. And if people whose profession implies at least the availability of skills to work with this personal protective equipment will easily cope with its use, then a simple number of civilians often have a number, including naive ones, of questions about gas masks.

In order to expand the representation of the ordinaryof the population of what is a gas mask and how to deal with it, representatives of one of the largest companies for the production of personal respiratory protective equipment gave answers to a number of popular questions asked not only by their clients, but also by people who have never seen a gas mask live.

Which gas mask will protect against everything?

1. Is there a universal gas mask?

This is probably one of the most popular questionspeople who never used a gas mask. There are even cases when, without a clear idea of ​​the scope of its application, people ask themselves: "What kind of gas mask will always help?" And stubbornly seek universal gas masks. Universal in their understanding is a gas mask that will suit anyone and protect against everything.

For the civilian population, only , which are fairly simple to apply andaffordable. Such devices are equipped with a filtering element, aimed at protecting only from a specific type of substances. In addition, this device only cleans the air entering the body, so another limitation in its use is the presence of a necessary proportion of oxygen in the infected atmosphere. It is clear that this type of gas mask must be selected exclusively within the scope of the filter element.

To a more or less universal type can be attributedIsolating gas masks that do not interact with the environment and work with any composition and concentration of hazardous substances in the air. However, such devices are not intended for the civilian population, since require special preparation before their application and in case of a sudden accident or in the process of emergency evacuation, an unprepared person simply can not use it.

2. What does NOT protect the gas mask?

Filtering gas mask, which is not possibleto enrich the air with oxygen, will be absolutely useless in conditions of insufficient oxygen for the human body (less than 17%). Also, the composition of standard filters does not provide protection against organic gases, including carbon monoxide. Therefore, it is always important to pay special attention to the composition of the filter elements and, if necessary, to purchase additional filters aimed at more extensive protection.

In addition, very carefully should be treatedto the proper use of gas mask. Since any error in its use - for example, a breach of the seal of the front part, the use of a gas mask with a defeated filter or any other element, can lead to harmful effects.

3. Will the gas mask help in case of fire?

The evolution of carbon monoxide in the event of a fire presentsdanger greater than the danger of open fire. The standard filtering gas mask is equipped with filters that protect against many types of poisonous substances, but it is not capable of filtering air from carbon monoxide, so it is useless in case of fire.

To protect against carbon monoxide there areadditional filtering elements that are purchased separately. But since most often their action is directed to air filtration only from carbon monoxide, and they do not protect from other combustion products, then such filters are used together with the standard ones included in the basic gas mask kit.

4. Can I suffocate in a gas mask?

You can suffocate without a gas mask. The device itself does not pose a direct threat, but there are very important nuances that must be considered before using a gas mask.

First, if the rules are not respecteduse is quite likely a lethal outcome in connection with the penetration of poisonous substances into the podmassochnoe space. For example, if the rubber mask is damaged or if it is not loosely adhered to the face, whether it is a filtering or an insulating mask, the effect of its protective elements becomes useless.

Secondly, in filtering gas masks, timethe action of the filters is always limited, and their use after the stated working time or after their complete working out also leads to undesirable consequences. Do not forget about the purpose of the filters - if the filter element is not properly matched, the gas mask will also be ineffective.

With regard to insulating gas masks, the work in them can be started strictly after the activation of the starting device that emits the first portions of clean air.

In addition, it should be remembered that while workingin the gas mask, resistance to breathing and pressure on the front part are noticeably felt, which significantly affects the working capacity and functioning of the whole organism. Therefore, all contraindications to the use of this type of device should be studied.

5. Is it possible to clean filters in gas masks or refuel oxygen cylinders at home?

All gas mask filters are disposable, that is,They contain an absorbent layer of activated carbon and paper membranes that can not be cleaned. Therefore, after working off the filter elements must be replaced with new ones.

As for filling oxygen cylinders,Such works can be carried out only in specially equipped laboratories, oxygen filling takes place under pressure, and at home it can not be done.
