“ The degree of respirator’s protection is influenced by many different factors, so for reliable protection of the workers’ health in the developed countries, the use of respirators is happening in the context of a comprehensive respiratory protection program. ”

“ For various reasons, industrial hygienists are not well taught the proper selection and use of respiratory protective equipment in the USSR and in the RF. There are no official documents in RF, that would determine when any respirators can be used, and indicates how to use them. No specific requirements for the replacement of gas cartridges, use a respirator with a constant pressure under the mask, there is no requirement for training workers. The absence of these requirements prevents develop training manuals, and constrains the application of modern western development. ”

“ When the sorbent was saturated enough, the contaminated air passes through the sorbent together with harmful substances, and harmful gases fall under the mask. Thus, the service life of the cartridges is limited. It depends on the concentration and properties of gases, the sorption capacity of the filter and its usage conditions (air flow, humidity, temperature) , as well as proper storage. If the gas filter is not replaced in a timely manner, the impact of harmful gases per worker exceeds the maximum allowable, which may cause damage to health. ”
