This contest is fueled by the following news: A gas mask is a means of protection for the respiratory organs and gas masks exist which also can protect the vision and face. The protective properties of gas masks differ according to the type of protection:
- From specific types of poisonous substances - filtering, filtering of ambient air, replacement of the filtering element is usually possible;
- Isolating - a generation of inhaling mixture - i.e. respiratory organs breathe not the air but air, generated by a cartridge;
- Hose - a supply of air mixture from some distance (10-40 meters) and this type of gas mask is usually used while carrying out work in tanks.
The world's first filtering coal gas mask was invented by Russian scientist Nikolay Dmitrovich Zelinsky in 1915. The filtering gas mask was inducted into the army Entente in the year 1916.

- Rubber helmet – mask;
- Filtering box;
- Eyeglass unit;
- Valve unit (one valve for inhaling and two valves for exhalation);
