The concept of acceptable (tolerable) risk in labour protection management
Zhuravleva M.A.
The paper deals with the current situation in labour protection management system for harmful industrial production of the Russian Federation and the main trends within the working conditions change in industry. Statistical data on the proportion of people employed in harmful and dangerous working conditions in the total number of employees is given as well. The reasons for this trend and inconsistency of the existing Russian legislation in the sphere of labour protection to the current economic model are considered, as well as the possibility of improving the labour protection management system based on the transition from compensation management model to the prediction one, and evaluating the likelihood of dangerous situations during the manufacturing process at the design stage. The concept of acceptable or tolerable risk is considered to be one of the most modern ways to achieve the desired security level. Its fundamentals are given. The definitions of risk and its main types are considered.
Keywords: labour protection management, risk, the concept of acceptable risk, labour conditions, manufacturing.

The system of cleaning the air from welding fumes
Ermolaeva V.A.
The paper presents the process of resistance welding as a source of occupational and environmental hazards. The excess amount of single-time maximum MAC of manganese, carbon monoxide and nitrogen dioxide, making up the welding fumes, is identified. It is advisable to replace general ventilation with a small-sized flexible system of local exhaust ventilation. The main types of dust collection devices and their application are analyzed. The choice of the given cleaning method is reasoned. The waste gas dust-air mixture should be cleaned by an electrostatic precipitator built into the local ventilation system. The calculation of electrostatic gas purification level and the efficiency of the given ventilation system are given. The selection and calculation of additional equipment (including fans and ductwork) are completed. The payment plan for air pollutant emission is presented, as well as the economic analysis of systems providing production and environmental safety.
Keywords: resistance welding, local exhaust ventilation, electrostatic precipitator.
