Ultraviolet Protection
Suitable eye protection must be worn when using shortwave emitting lamps. Shortwave can produce skin burns. Protective clothing or barrier creams should be worn on exposed skin areas. Avoid shining UV light on reflective surfaces. Longwave ultra-violet is considered generally harmless. However some people may be particularly sensitive and care must be exercised whenever UV light is used.
