Gas mask Filtering

A filter gas mask (P.) is a protective device designed to protect the human respiratory system from harmful impurities in the air when working in conditions where the concentration of these impurities exceeds the maximum permissible values. The operating principle of P. is based on the filtration of inhaled air through special substances that absorb or neutralize harmful impurities, thereby ensuring human safety and health.

P. filters can be of various types and designs, depending on what harmful impurities need to be absorbed or neutralized. For example, filters for protection against organic substances may contain activated carbon, and filters for protection against acid gases and vapors may contain special reagents such as sodium or potassium.

It is important to note that the use of P. requires compliance with certain rules and safety measures. First of all, you should choose the right size of gas mask and securely fasten it on your head. In addition, when using P., it is necessary to monitor the condition of the filters and replace them in a timely manner.

Filter gas masks are widely used in various industries, such as chemical, oil refining, metallurgical, mining and others. They are also used in medicine, transport and other areas where respiratory protection from harmful impurities is required.

A modern gas mask is not just a filter for protection against harmful gases and dust, but also a comprehensive personal protective equipment that should ensure complete safety for its owner. It consists of the main elements: a helmet-mask, an air filter, and a gas cartridge.

1.1 Helmet - gas mask. A helmet is a mandatory element of a protective set for a person’s head, which must meet certain requirements. Initially it was used for emergency exit in cases of emergency. Currently, it is widely popular all over the world: Russia (Tourist model “PSHM-84”), America (“REACTOR U”, “OTV”, “HAZMAT”, “DECON”, “KINGSEC”), Germany (Brandschutzmaske Band M2 ) etc. As a rule, the helmet is adapted to the individual features of the facial structure and can be changed using special fasteners. Gas masks can be used both at home and at work. Seemingly small differences in design include different types of air filters, making the models incompatible with each other.
