Annotation. The widespread introduction of laser products in various fields of science, technology and medicine, as well as the possibility of serious damage to the organ of vision and skin during their operation, put forward new and increasingly complex tasks for laser hygiene. An analysis of the hygienic normative and methodological documents currently in force on the territory of the Russian Federation showed that they cannot fully ensure laser safety. Differences in the approaches to the hygienic standardization of laser radiation (LR), adopted in the Russian Federation and the USA and the European Union, have been established. The LR hygienic standards in GOST R IEC 60825-1-2013 are practically identical to foreign IEC 60825 standards, that is, in most spectral ranges they exceed the MPL by an order of magnitude or more (SanPiN 1.2.3685-21). The necessity of correcting the hygienic standards of LR, harmonizing the classification of lasers according to the degree of hazard, and developing effective means of control and protection was revealed. Draft documents have been developed: "Hygienic standards for laser radiation" and "Sanitary and epidemiological requirements for working conditions during the operation of laser products", the introduction of which into the practice of sanitary and epidemiological supervision will ensure the preservation of the health of workers. Key words: lasers, correction of hygienic standards, classification, methods and means of control and protection, laser safety.

Have been considered calculating methods for hazard evaluation of diffusely-reflected laser radiation at work places for operators of laser technological units (LTU), realized for purposes of special assessment for working conditions (SAWC). Examples for calculating SAWC at work places for operators of modern LTU applied in shipbuilding have been given.

Search For Information

Introduction. The article presents an analysis of the existing Russian and foreign literature on the issue of domestic and international regulation of laser safety for the population. Purpose. Search for information and analysis of domestic and international experience in the field of regulation of laser radiation levels for the population. The review of available scientific Russian and foreign literary sources and regulatory documents is carried out. The search and selection of sources was carried out using the open databases PubMed and RSCI. The domestic hygienic standards for continuous laser radiation in the spectral range of 380-1400 nm are much more stringent than the standards applied abroad given in IEC-1. At the same time, when developing standards for maximum permissible levels, the possibility of radiation acting on the population and the blinding effect were not taken into account. Foreign and domestic authors note the peculiarities of the effect of laser radiation in the visible region of the spectrum, including its ability to pass freely through the optical media of the eye and damage the retina and adjacent tissues. The analysis of regulatory documents showed a number of differences in the normalization of Russian and international standards, as well as the discrepancy and vagueness of requirements in existing sanitary and epidemiological documents. Conclusion. Existing standards sometimes contradict each other, which prevents a competent assessment of the danger of the laser and the laser system, so the revision of the existing regulatory framework for laser safety for the public is an urgent task, the solution of which will minimize negative changes on the part of the visual organ in persons who are not professionally connected with the action of laser radiation and qualitatively improve the hygienic assessment of laser radiation.
