man needs to protect the body.This is due to many factors: the place of work that requires use of personal protective equipment, a high level of environmental pollution and, as a consequence, the need to protect, as well as emergency situations (fire, accident) or, in the end the state of war.The purpose of using such agents is that harmful substances, bacteria, toxic gases are not able to harm humans externally or internally.How to protect the respiratory system, which attributes are required for this and how to use them - in our today's article.
General
Personal respiratory protection are of three kinds: to protect against dust (mask PTM, bandage gauze and cotton), different in the level and method of protection masks and gas masks, which, in turn, are divided into two categories: insulating and filtering.First applied in emergency situations when the oxygen is too contaminated by hazardous substances (often applied in time of war).These include hose phones and personal respiratory protection, in which fresh air is taken from the special balloon with oxygen or compressed air.The second type (filter products) include means which operate at less than optimal and hazardous conditions (more than 17% oxygen).Next, a more detailed account of the remedies that may be useful in everyday life - masks and respirators.
filter masks
How the device works: in the protection box (which is under the chin), the contaminated air is cleaned, then fed to the face.Harmful substances disappear by adsorption, catalysis and chemisorption.
use: worn from the chin to the top of the head, pulled sharply.After donning should not remain uneven.It is important to know what you need before putting on hold in light air.You can resume breathing after being put on a gas mask.Features of use: you can not use it to protect the seriously wounded or sick people with the vessels of the head, with unstable pressure, meningitis.However, such personal respiratory protection as opposed to isolating perfect for additional training, training.It should be noted, however, that in the cold winter is necessary to process the neck and the face behind the mask from chapping.
Respirators: types
They are fairly easy to use, unlike the mask.With their help, depending on the level of the respirator can be prevented both from street dust and industrial dust.Furthermore, they are used in wartime, in medicine, etc.Such means respiratory protection is worn on the face, the ears attached.Respirators are divided into three types: anti-dust, anti-gas, as well as masks with combined capacity of the first two.The thin but durable materials against dust respirators are used as protection against aerosols.The latter is used in conditions of oxygen compounds of phosphorus and chlorine.Such personal respiratory protection are also used in the presence of air, acetone, benzene, and other organic compounds.
