Despite wide legislation basis of regulating relations in work safety and workers’ health, one third of workplaces demonstrate exceeded allowable normal levels of workers’ exposure to occupational hazards and present occupational risk for health disorders.In accordance to national legislation acts, evaluation should cover factors of occupational environment and working process, and occupational risk is understood in context of mandatory social insurance. This approach has been formed due to mostly compensatory trend in legal principles of work safety in Russia by now. Implementation of new preventive concept of work safety, based on idea of risk management for workers, necessitates development of legal acts that regulate requirements to evaluation of occupational risk and its reports with consideration of changes in Federal Law on 30 March 1999 №52 FZ “On sanitary epidemiologic well-being of population”.Those acts can include Sanitary Rules and Regulations “Evaluation of occupational risk for workers’ health”, that will contain main principles of risk assessment, requirements to risk assessment, including its characteristics which can serve as a basis of categorizing the risk levels with acceptability.To standardize requirements for informing a worker on the occupational risk, the expediency is specification of sanitary rules “Notifying a worker on occupational risk”. These rules should contain requirements: to a source of data on occupational risk level at workplace, to informational content and to ways of notifying the worker. Specification and implementation of the stated documents enable to fulfil legal requirements completely on work safety — that will provide preservation and increase of efficiency in using work resources.

The article presents the modernization of the design of the universal seed mordant PSS-20 by installing an axial fan and air ducts for closed air circulation in the processing chamber, which will ensure the full use of the mordant, work safety and increase the productivity of cultivated crops. The main advantage of this design is that the seeds in the same plane as the suspension flow is affected by the air flow, which improves the penetration into the layer. Air ducts make it possible to reuse the suspension that has not settled on the seeds. This is achieved due to the closed lid design. During operation, the fan creates excessive pressure inside the seed stream and rarefaction outside, and so small drops of solution that have penetrated the seed stream are sucked in by the fan and re-fed into the stream.

Wood splitting, manual as well as mechanized one is a heavy work. It follows from the fact that usually the wood of the least quality, knot wood with scroll fibres, directed for less valuable assortments from the point of view of the price. Present technique on the contrary is relatively price demanding, requesting besides 2–4 members of operating personnel also adequate concentration of wood mass for the reason of the complete process economic efficiency. We submit in this paper technology analysis of the splitter WS 800 performance with the original concept for the wood manipulation and splitting process as well. Essential advantages of the mentioned splitter comparing with the stationary equipments are operational and interoperational wood manipulation, physical effort and operating personnel elimination, while the efficiency and work safety is increasing.
