Personal respiratory protection

A person needs to protect the body. This is due to many factors: the place of work, which requires the use of personal protective equipment, a high level of environmental pollution and, as a consequence, the need for protection, as well as emergency situations (fire, accident) or, ultimately, martial law. The purpose of using such funds is that harmful substances, bacteria, poisonous gases could not harm a person externally or internally. How to protect the respiratory system, what attributes are required for this and how to use them - in our today's material.

general information
Personal respiratory protection can be of three types: dust-protecting (PTM masks, gauze and cotton bandages), 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, when the oxygen is too polluted from harmful substances (often applicable during the period of military operations). These include hose assemblies and personal protective equipment for respiratory organs, in which clean air is taken from a special cylinder with oxygen or compressed air. The second type (filter products) includes products that work under more optimal and less harmful conditions (more than 17% oxygen). Next, we will talk in more detail about the protective equipment that can be useful in everyday life - about gas masks and respirators.

Filter masks
How the device works: in the gas mask box (which is under the chin), the contaminated air is cleaned, then it comes to the face. Harmful substances disappear due to adsorption, catalysis and chemisorption.
Use: worn from the chin to the crown, pulled sharply. After donning, no bumps should remain. It is important to know that before donning, air must be held in the lungs. You can resume breathing after you put on a gas mask. Features of use: you can not use it to protect seriously injured or people with diseased vessels of the head, with unstable pressure, meningitis. Moreover, such personal protective equipment for respiratory organs, in contrast to isolating ones, is excellent for additional training and training. However, it is worth noting that in cold winters you need to treat the neck and face under a mask of weathering.

Respirators: types

They are quite simple to use, unlike a gas mask. With their help, depending on the level of the respirator, you can protect yourself from street dust and industrial dust. In addition, they are used in war conditions, in medicine, etc. Such a respiratory protective equipment is worn on the face, attached to the ears. Respirators are divided into three types: against dust, gas masks, and also respirators with the combined capabilities of the first two. Thanks to the thin but durable material, anti-dust respirators are used as protection against aerosols. The second is used under conditions of oxygen content of phosphorus and chlorine compounds. Such respiratory protective equipment is also used in the presence of acetone, gasoline and other organic compounds in the air.
