To improve the reliability of respiratory protection available for workers handling dry mixtures, when dust and noxious gases penetrate the work area, it is necessary to both upgrade the design of the respirators currently in use, and develop new porous layer materials to enhance the protection level along with user convenience. An ion-exchange filtering material has been developed, which offers both protective and hygienic properties. A mathematical model has been created to simulate the half-mask casing of a Snezhok GP-V type respirator. The finite element method was used for stress analysis of the casing.
