The article once again highlights the problem of injury growth in our country. The article presents the developed digital jumpsuit for work at height, excluding the possibility of violation of the rules of TB, controlling the integrity of the belts. It is concluded that human security, his life can not be given to him only in a rapidly developing technogenic society, a person should actively help digital technology

The analysis of existing methods of water use when applied galvanic coatings in the automobile transport sector. It is established that under the existing schemes of water use in the galvanic production wastewater after cleaning goes into the sewer, keeping the risk of contamination of open reservoirs. In such circumstances, the most effective is the use of system of the closed water cycle, which with the help of automatic control allows to take into account changes in the concentration of substances laundered in the washing baths providing the required quality of washing parts with a minimum consumption of water resources.

This article presents the results of tests of samples on the basis of equiatomic alloy with shape memory effect. The obtained system of dimensionless quantities that adequately describe the elastic-plastic deformation. It is established that the assessment of scale effects in modeling shockproof device-based alloy with shape memory effect leads to the technical ability of extrapolation of experimental results to other objects to generate the initial data of the mathematical model under the condition of similarity of characteristics of external loads.

The analysis of domestic innovative solutions describing shock devices. Topical area of research is to reduce the dimensions of such devices while maintaining their energopogloschatelnoy capacity and use of new materials such as shape memory alloys. A method for testing such devices with elements made from these materials.
