a set of factors of the production environment and the work process that affect the working capacity and health of the employee. According to the degree of harmfulness and danger, working conditions are divided into four classes:
1) Optimal – there is no impact of harmful and (or) hazardous production factors or the levels of exposure do not exceed the established standards.
2) Permissible – the employee is exposed to harmful and (or) dangerous factors, the levels of exposure to which do not exceed the standards, and the altered functional state of the body is restored during the regulated rest or by the beginning of the next working day (shift).
3) Harmful – the levels of exposure to harmful and (or) hazardous production factors exceed the standards.
4) Hazardous – the levels of exposure to harmful and (or) hazardous production factors during the entire working day (shift) or part thereof can pose a threat to the life of an employee, and the consequences of exposure cause a high risk of developing an acute occupational disease.
