The article determines the relevance of the problem of rising injuries in the country. The article presents an algorithm for choosing the means of protecting workers from falling from a height. An innovative safety system for working at heights virtually eliminates the possibility of violating the rules of safety requirements, which can ensure human safety in a rapidly developing technogenic digital society.
The article describes the methods of production management, providing, in addition to improving productivity, the normalization of harmful and dangerous factors of the working environment. By results of comparison of the main indicators of individual professional risk of the worker the interrelation between improvement of working conditions and introduction of lean production in foundry is proved. The conclusion is made about the efficiency of lean production methods in terms of professional risk management.
Application of modern methods of the theory of fuzzy sets and the theory of decision-making to a problem of construction of an integral index of safety in multicriteria spatio-textual signs on the basis of axiomatically entered concept of sufficiency is considered. The ways of constructing a complex index of safety in the production of lifting machines using computer algorithms that al-low a qualitatively new level to solve the problem of processing a large amount of information necessary to improve the reliability of the estimates. The proposed method can be adapted for specific objects by expanding or changing the multi-criteria space of particular features that characterize the safety of operation of these objects in real conditions.
Observations of the operation of jig back rope-ways allowed us to suggest the presence of torsion of track cables of a closed structure under the influence of operational loads. In this case, the total weight of the cable and the car is a trans-verse load, and the cable itself is loaded with longitudinal resistance forces in its individual sections. The paper provides theoretical substantiation and experimental confirmation of the presence of torsional deformations of track cables of jig back ropeways under the influence of friction between the cable and the rocking saddles. A new method of rejection of such cables based on the control of torsional deformations is proposed.
When organizing a site for the processing of used tires at a motor transport enterprise, a wide range of harmful and hazardous production factors leads to increased noise levels. The source of his education is a disintegrator. It was established that at the studied workplace the equivalent sound level is 88 dBA with a norm of not more than 80 dBA (for the 2nd class). Not only the operator, but also workers performing their labor functions nearby are ex-posed to noise in the study area. The solution to the problem of reducing noise exposure is associated with a preliminary calculation of acoustic screens, determining the necessary area of sound-absorbing material, fasteners, etc. The performed studies show the need to install 7 screens with a total area of 20 m2 to satisfactorily reduce the sound level to the values regulated by sanitary and hygienic requirements. A decrease in the prevailing factor will entail a general decrease in the class of working conditions by hazard and hazard of the operator by one degree.
The article discusses the problem areas of the Combine Builders Square in Rostov-on-Don and possible measures that could improve traffic at this roundabout. Environmental indicators were calculated after carrying out the proposed measures to reduce CO emissions by cars. A comparative analysis of indicators before and after the events. The data obtained made it possible to establish how much the proposed measures to optimize traffic will help to reduce CO emissions by cars.
