Personal respiratory protection
A person needs protection of the body. This is due to a number of factors: a place of work that requires the use of personal protective equipment, a high level of pollution of the environment and, as a consequence, the need for protection, as well as emergency situations (fire, road accidents) or, in the end, martial law. The purpose of using such means is that harmful substances, bacteria, poison gases can not harm a person externally or internally. How to protect the respiratory organs, what attributes are required for this and how to use them - in our today's material.
Personal respiratory protectionThere are three types: dust protecting (PTM masks, gauze bandages and cotton wool), respirators and gas masks of different levels and methods of protection, which, in turn, are divided into two categories: insulating and filtering. The former are applicable in emergency situations, with too much contaminated oxygen from harmful substances (often applicable during the period of hostilities). These include hose devices and personal respiratory protective equipment, in which clean air is taken from a special cylinder with oxygen or compressed air. The second type (filter products) includes facilities that operate under more optimal and less harmful conditions (more than 17% of oxygen). Next, we will talk in more detail about the means of protection that can be useful in everyday life - about gas masks and respirators.
Filtering gas masks
How the device works: in the gas-mask box (which is under the chin), the polluted air is cleaned, then comes to the person. Harmful substances disappear due to adsorption, catalysis and chemisorption.
Using: puts on from the chin to the crown, stretches sharply. After putting on, there should be no unevenness. It is important to know that before putting on you need to hold the air in your lungs. You can resume breathing after you put on a gas mask. Features of use: it is impossible to use it to protect seriously wounded people or people with sick vessels of the head, with unstable pressure, meningitis. At the same time, such personal respiratory protection means, unlike isolators, are great for additional training and training. It is worth noting, however, that in cold winter conditions it is necessary to treat the neck and face under the mask from airing.
They are fairly simple to use, unlikefrom the gas mask. With their help, depending on the level of the respirator can be protected from both street dust and industrial dust. In addition, they are used in war conditions, in medicine, etc. Such a means of individual protection of the respiratory organs is worn on the face, fastened behind the ears. The respirators are divided into three types: dust, gas and respirators with the combined capabilities of the first two. Thanks to a thin, but durable material, dustproof respirators are used as a protection against aerosols. The latter are used in conditions of oxygen in the compounds of phosphorus and chlorine. Such personal protective equipment for respiratory organs is also used in the presence of acetone, gasoline and other organic compounds in the air.
