3.4 UV Light Safety Considerations

Mercury arc lamps have UV light content in their output. The U.S. National Institute for

Occupational Safety and Health (NIOSH) recommends that exposure to UV energy be

controlled and limited as much as practically possible.

Exposure to UV radiation even for very brief periods of time can be hazardous. The

potential damage depends on exposure time, the type of UV light and the individuals

sensitivity to UV.

UV light causes sunburn. Long term exposure can result in loss of skin elasticity initially

and carcinoma eventually.

Absorption of UV light by the eyes will cause inflammation of the cornea called photo

keratisis. Continued exposure can lead to the formation of cataracts on the eye lens.

Therefore, the following safety considerations should be taken very seriously:

• Limit access to areas where UV light is present.

• Post warning signs in the area where the equipment is installed.

• Always wear protective eyewear and gloves.

• Be sure your arms and neck are covered.

• Never directly look at the light source.

• Close off the light source with the filter slider when not being used.
