Prospects for the development of breathing apparatus using chemically bound oxygen

Introduction. This paper examines the tactical and technical characteristics of various breathing apparatuses in service with the gas and smoke protection service in the fire protection units of the Russian Federation — compressed air breathing apparatus, compressed oxygen breathing apparatus, and also substantiates the need for the development of domestic breathing apparatuses on chemically bound oxygen. The relevance of this paper is the lack of modern domestic breathing apparatus with a long period of protective action for effective fire extinguishing.

Aims and Objectives. The aim of this paper is to improve the equipment of the gas and smoke protection service of fire protection units with the most effective and suitable breathing apparatus for extinguishing fires at metro stations, harbour yards and ships, underground car parks and high-rise buildings.

Materials and methods. An analytical approach is used to consider personal respiratory protection equipment, which are in service in all types of fire protection in our country, the characteristics of various types of chemically bonded oxygen breathing apparatus are analyzed in detail and their comparative analysis is carried out.

Results and their discussion. As a result of the study, recommendations were made to improve the equipment of fire departments with breathing apparatus. The authors gave recommendations for some changes in the re­gulatory legal acts of the Russian Federation.

Conclusions. A reasonable conclusion was obtained about the effectiveness and necessity of introducing breathing apparatus based on chemically bound oxygen and supplementing them with gas and smoke protection service of fire and rescue units. Also, in the absence of breathing apparatus of this type at the moment, the authors of the paper presented proposals that should be taken as a basis for the production of completely new breathing apparatus and sets of front parts with adapters for attachment to a fire helmet, as well as proposals for amendments to the regulatory legal documents of the Russian Federation and the necessary abbreviation for their designation are given.
