Abstract

The paper describes adapting problems for respirators, produced in Ukraine to European standards. It was found that the Leaf type respirator of FPP material doesn’t meet the parameters of DSTU EN 149: 2003 at a rate of dust penetration through the respirator filter after thermal and mechanical influences and flameproof. Study has shown, that increasing duration of heat exposur the structure of the filter material undergoes irreversible changes. This leads to a decrease in the protective efficiency. Using polypropylene filter materials allow replacing FPP materials, which indicators meets European standards, and do not contradict the traditional view of potential consumers.
