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.
