[Occupational hygiene and health status in welders of laser devices].

Welders-assemblers of the Quant-type laser devices are exposed to bright light flashes of plasma and laser exceeding in certain measurements the maximal allowed level. Such hazards induce disorders in eyes, autonomic nervous, circulatory and immune systems of workers. Impaired humoral immunity can lead to increased incidence of acute respiratory tract diseases. Prophylactic measures, including laser and flash shielding screens and drug therapy were suggested.

[The hygienic bases of laser safety].

Exploitation of laser devices exposes the workers to reflected low-intensity radiation and concomitant physical and chemical factors. Clinical and experimental studies revealed the structural and functional disorders in the organs and body systems exposed to long and constant action of the stated factors, which let the changes be considered as a criterion of the harmful action and serve to base the maximal allowable conditions and assure the safe work conditions when handling laser devices. Harmful and dangerous factors produced by laser device and used materials necessitate the creation of laser equipment of different types and purposes, that will be safe for the personnel handling it.

[Hygienic evaluation of new laser technology units].

The study revealed that the levels of lazer irradiation diffusion in working places, in case with the "Biryuza" technological equipment, were lower MAC. The other occupational factors, violating the accepted hygienic norms, were connected with improper hygienic control measures at the stage of equipment processing and usage. A set of labour conditions improvement measures was proposed.
