Background. Professional risk management. An assessment of their impact on the occupational diseases and search of the ways for reduction of the occupational diseases of a dust etiology in the employees of mining enterprises.
Objective. We determined a professional risk level of the occurrence of dust etiology respiratory diseases in miners while using respirators.
Materials and methods: For the calculation of risk level we used a technique offered by prof. Novikov S.M. On its basis we obtained the results confirming that dust effect built up with a significant MAC excess and an increase of time of the workers’ stay in the area of dust factor effect.
Results. The anti-dust respirators were established to reduce a risk degree not more than by 50% that didn’t allow a sufficient level of the protection of miners. With this provision, an excess of dust concentration in under-mask space in the AA respirator at dust content of 150 mg/m3 in mine working reaches about 40% that is dangerous for the health of miners.
Conclusions. A risk of the occurrence of dust etiology diseases can be decreased owing to properly fitted qualitative anti-dust respirators but not to the safe level. It needs not only to improve a respirator design but also to provide motivation for their use by the miners.
