Abstract

The article discusses the problem of determining safe work experience in conditions of increased intensity of hard work. It is especially relevant in construction industry. The need for an objective analysis of industrial accidents is an urgent task not only for the prevention of injuries, but also for improving environmental safety, interpreted as occupational risk management in order to protect the health of people of active working age. The research methodology was based on the analysis of the characteristics of the occupational diseases risk, depending on the level of existing harmful production factors, as well as the length of service. Occupational risk is directly related to the dynamics of changes in harmful and hazardous production factors during an employee's work experience. This risk gradually increases nonlinearly over the course of the employee's work experience, and in the experience sector the risk begins changing at an increasing rate. The new system for assessing working conditions introduced in 2014 in Russia, although it helps to reduce the annual increase in risk, but cannot provide completely environmentally friendly and safe working conditions and acceptable risk (R). The environmental safety of production activities is a big question and is at high risk in the construction industry, in particular due to the huge number of concealment of occupational injuries, violations of the regenerative capacity of the human body, as well as the extension of the retirement age to 65 and 70 years. Therefore, it is required to introduce a mechanism (model), providing a real system for assessing working conditions.
