Respiratory protection. Respirator RPG-67. Insulating mask
In order for a person to survive in adverse environmental conditions that are created by his own hands along with the vagaries of nature, he must use special means invented to increase the chances of preserving life and health. Respiratory protection means can prevent a variety of diseases, make it possible to work in conditions of increased air pollution. Scientific and technological progress by leaps and bounds goes to perfection, creating ideal tools for human comfort and well-being. We sometimes do not even guess how a simple rubber or gauze device can save a life or soften a chemical blow.
Specificity of use of protective means
It is impossible to say unequivocally what kind of devices that filter atmospheric admixtures are needed, if there is no exact description of the situation in which it will be applied. When purchasing a respiratory protection device, it is necessary to specify, if possible, what substances will be present in the air. This does not mean that in an emergency, you should not expect that you will be able to protect your body from poisons and smoke. It is desirable to indicate the working conditions, the description of the substances to be contacted, the area of the room where the person will be.
Perhaps, only a filtering half mask is needed instead of a more serious means - a gas mask. Value does not matter, because in some cases, the absence of a mask can be a threat not only to health, but also to a person's life. When buying, you must specify the age of the person planning to use the simplest respiratory protection. For example, respirators have a size range, teenage products by volume differ from adults in the smaller side.
Varieties of filtering devices
- The gas mask is the main respiratory protection. It helps to prevent breathing, as well as eyes and face from not only suffocating smoke, but also toxic, chemically hazardous substances. For employees of secret laboratories such an insulating mask will become an excellent barrier to the penetration into the body of bacterial products of biological origin, radioactive vapors and various kinds of aerosols.
- Gas dustguard respirator is a functional and convenient product of scientific and technical progress, which allows to protect human respiratory organs from fetid and poisonous vapors, gases, aerosols of the AHOV type. It should be noted that such filtering respiratory protection is effective only at low concentrations (within the 10-15 MPC mark). The most common respirators are RU-60M (used with KD and B cartridges), RPG-67 (KD cartridge) and a product with the interesting name "Snowball-GP-E", which does not cancel its effectiveness. The respirator-half mask with the marking RU-60M, like the RPG-67, got its name due to its appearance - it's a rubber half mask with a knitted obturator.
- Civil gas masks protect from the release of AHOV and are the most accessible and popular among the world's population. Such filtering equipment can be purchased independently in a specialized store, detailing exactly where it is planned to use it, and indicating the age of the person to whom the product will be directly worn.
How to make the right choice
Classification of respiratory protection devices may include additional subspecies, which are used in individual cases. To understand exactly what kind of device you need for air filtration, you should consider each of them in more detail. Even if this information is not relevant at the moment, situations in the future are not ruled out, when there is an urgent need for a gas mask or respirator. It is not meant that immediately it is necessary to purchase batches of remedies and store them in the basement before the advent of a suitable case. If a person is sufficiently informed about what he may need, then it will be easier for him to cope with any non-standard life stage. Gauze masks that can be made with their own hands are not so relevant: they can protect in a smoke-filled room during a fire, but no more. Only serious preparation is a guarantee of security in the future.
Gas-dust protective respirators
In addition to the main specific masks listed in the list, the following subspecies exist: the RU-6OM respirator is a fairly common respiratory protection device that comes with two cartridges that absorb harmful vapors and poisonous substances. In such a product there is a charge and an additional filter.
It protects the body from vapors and AHOV. Particular attention should be paid to the device "Snowball-GP-E", which has in its simple at first glance design two filters - dust-aerosol and absorbing. If you use such a convenient mask, you can protect yourself completely from aerosols that fly in the air, substances of biological origin, AXOV gases (the latter include hydrogen fluoride, chlorine, sulfurous anhydride, hydrogen chloride). This is a great help for those who work on objects of high atmospheric pollution or just decided to protect potato shoots from Colorado beetles. No matter how strong the poison is in the atomizer, protection is guaranteed.
Sphere of use of respirators
It should be noted that such respiratory masks have limited use. This means that they will not protect eyes and skin from AHOV (such a filtering component is put on the mouth and nose area, securely fastened behind the firm rubber band, in order to avoid slipping through the hair and scalp). Scope of use - industrial. And to the person planning to wear such a gas mask, there are some strict requirements, prescribed in the rules of industrial sanitation. A special point is the protection of human respiratory organs not only from harmful substances (gases, vapors, etc.), but also from mechanical impurities that have a negligible weight and can be freely suspended. "Will it protect the respirator from dust or harmful substances?" - a question that needs to be approached in detail, carefully analyzing the situation in advance.
Filtering gas masks
Such a remedy is made by the industrial forces to protect workers in factories that come into contact on a daily basis with chemically hazardous substances. As a rule, such an insulating gas mask is used in combination with protective clothing and footwear. It has two main subspecies: industrial gas masks (as mentioned earlier, for employees of laboratories, industries and other facilities) and civil (for any category of the population in the event of an unfavorable situation with a life risk). The sphere of use of industrial gas masks is protection from harmful chemical elements when their concentration in the room air exceeds the permissible standards.
Use of such special filters of a special design is possible only taking into account the types of poisons or strong substances, that is, after their additional analysis. If the head of the company takes care of his employees, he will check everything in advance and only after that will be able to order gas masks for all employees. They are produced by different manufacturers in all trim levels, with different filter boxes. The latter are especially relevant for consideration, since each of them has the ability to selectively absorb harmful substances and mechanical impurities in a suspended state that are in the room.
Civil gas mask: distribution and functions
If we touch on the issue of choosing a filter of harmful poisons, then the respiratory protection in this regard has reached unprecedented progress. It means that not only can you order their specialized types, but also buy in a store that deals with the supply of such goods. For example, you can buy a gas mask. It will protect the respiratory system in full, as in its design there are appropriate filters. At present, it is the most popular and sought-after means of separating clean air from impurities. It is available for everyone, but it's important to know the size in order not to be mistaken. For example, for a teenager the adult model will be great. This can not be neglected, since in case of fire or work with poisons this product can simply slip off the head and leave the person alone with danger. The loose-fitting gas mask also does not provide adequate protection. We must not forget that for a growing organism such carelessness can become pernicious and cause irreparable harm to all systems: blood, respiratory, damage the mucous membranes of the eyes and others. The basic respiratory protection listed above will help in any situation where there is a danger of a chemical explosion or the release of hazardous substances from factories located within the city or nearby. Practically in every city there are chemical plants that produce useful things for everyday life. But any emergency situation can be dangerous for the entire urban population.
RPG 67. Scope of use
Particular attention will be paid to such a product as the RPG-67 respirator. It belongs to the category of filtering gas appliances, which will fully protect the body if necessary. This model is mainly used to protect human respiratory organs of any age from exposure to harmful substances in a state of vapor or gas. If it comes to the industry - then from those present in the air premises (usually closed), namely the work area. In it, a person spends most of his time, so the daily impact on his body of poisonous impurities can not only adversely affect his health, but also reduce the length of time allotted to life, however regrettable.
Design of the respirator
RPG-67 consists of the following main parts: the basis - rubber half-mask with the marking of PR-7, fabric or rubber obturator, depending on the manufacturer's preference for several filter cartridges. Also there are plastic cuffs in which the inhalation valves, the exhalation valve are mounted. There is a safety screen and a clearly planned size of the headband. The respirator RPG-67 is easy to choose - its marking exactly corresponds to the designation of cartridges that fulfill the filter function. Each of them has a different composition of absorbers. That there was no confusion (after all, the protection of the respiratory system is a very serious process), the marking of each filtering product is applied strictly in the center of the cartridge cover. In this case, the date of manufacture, as well as the model and brand of the cartridge component, must be indicated.
Range of respirators
Usually manufactured by the manufacturer respirators with the sizes of half masks of three kinds: 1, 2, 3. Depending on the head circumference and the age of the consumer, choose the suitable one. You can also purchase a separate set of protective eyewear that protects the human eye, which wants to put a powerful barrier between your body and the harmful environment. The RPG-67 respirator has some nuances when used. One of the most important: it is forbidden to use this product to protect against highly toxic substances. The fact is that in this case its filters can not cope with their functions. Such substances include hydrocyanic acid, hydrogen sulphide, arsenic, hydrogen phosphorous, cyanides, methane, tetraethyl lead, ethane. Some substances in vapor-gas-like state can still penetrate the body, for example, if some parts of the skin are not protected.
Every person has to deal with different harmful substances from time to time, situations can also be different: a working moment or a supernumerary event. When choosing a remedy, it is necessary to take into account all generally accepted norms and factors, the ignoring of which can lead to disastrous consequences. The filter box of any product is always strictly specialized, it is oriented to a certain composition of absorbers.
Your health should always be treated with great care. If there is a possibility to prevent any life-threatening situation, then it is simply necessary to do so. Respiratory protection is a necessity, not a luxury. Their cost is always within the limits of available, and if in the country there are ecological cataclysms or technogenic catastrophes, it can even be lowered in the calculation of low-income strata of the population. The state is able to take care of us to some extent, but everyone must make maximum efforts to ensure their protection.
