Lasers have a small divergence of the beam, which can be focused and at the same time create significant energy densities. These unique properties allow them to be used in various fields of science and technology, communication and industry, in agriculture and medicine, in the construction of large engineering structures in instrument and mechanical engineering, electronics, etc. At the same time, such widespread use of lasers increases the number of working personnel exposed to laser radiation. That is why it is so important to pay attention to preventive measures aimed at preventing and minimizing the manifestation of this dangerous and harmful factor on the human body. Depending on the design features of lasers and the conditions of their operation and use, a number of dangerous production factors can be determined when working with them [1]:
