SHDA — hose Breathing Apparatus of JSC TSASF

SHDA — a hose-type breathing apparatus on compressed air, is a means of individual protection of complex design, protecting the user from death or dangers that can cause irreversible harm to health. The first hose-type breathing apparatus on compressed air in Russia was developed in 1996 by specialists of JSC "CASF". The hose-type breathing apparatus replaced the used hose-type breathing apparatuses with an air purification system through a filter box; in the proposed SHDA, the breathing resistance due to excess pressure under the mask is significantly lower than in apparatuses with filter boxes. Hose-type breathing apparatuses manufactured by JSC "CASF" are certified and comply with the requirements of TR CU 019/2011 "On the safety of individual protective equipment". The SHDA protects the respiratory organs and vision of a person when performing various types of high-risk work in wells, reservoirs, cisterns, reactors, etc., in a confined space, when the inhaled air is dangerous due to the high concentration of toxic, suffocating substances or low oxygen content. The design of the industrial hose breathing apparatus manufactured by JSC "CASF" is extremely reliable. An autonomous source of compressed air is located on the wearable part of the breathing apparatus - a reserve cylinder, designed to exit the rescuer from the danger zone in the event of an emergency (breakage of the main hose and when the compressed air in the working source is exhausted). The mobile compressed air source "Istok-50"* or "Istok-20"* can be used as a working source.
