Damage to the skin may occur from exposure to laser light in the range of 230-380 nm. The most serious hazard from the operation of high powered lasers is the possibility of electrical shock. The operator must be cognizant of those areas where high voltage is present. Optimally, access to high voltage electricity should be physically restricted wherever possible. Visual inspections should be performed by laser users to check for appropriate insulation of high voltage contacts.
Some lasers use chemical dyes and solvents.
If hazardous chemicals come into contact with your skin or eyes, flush immediately with water and call 911 for assistance.
