Improving the Process of Managing Psychosocial Risks in Organizations.

Introduction: Psychosocial risks (PSRs) are identified as one of the main modern occupational safety issues, primarily related to occupational stress, and need to be reduced to safe levels in accordance with international requirements. The research purpose is to improve the process of managing the PSRs in the occupational safety and health management systems of employees, taking into account the impact of psychosocial dangers in accordance with the requirements of ISO 45001:2018 and ISO 45003:2021 standards.

Methods: To develop the process of managing the PSRs, a system analysis method is applied, which allows determining the structural relationships between the variable elements of dangerous psychosocial factors described in the ISO 45003:2021 standard.

Evaluation of properties of elastomeric head straps of filtering facepiece respirators.

Frequent donning and doffing of filtering facepiece respirators (FFRs) can reduce their effectiveness due to the residual deformation of their elastic head straps. This study investigates the loss of elasticity of head straps during repeated use. Five elastomeric tapes were tested as FFR head straps, and their tensile strength was measured using a DU-100 dynamometer after repeated donning and doffing cycles.

Development of an algorithm for effective design of respirator half-masks and encapsulated particle filters.

Social and economic situations in the modern world require new approaches to the development of respiratory protective equipment. This study aimed to improve the three-dimensional modeling process for respirator half-masks and encapsulated particle filters. Basic provisions of the theory of non-stationary filtration and hydroaerodynamics, the Nelder-Mead method and the linear interpolation equation were used.
