Scott, thank you for your help regarding trying to find information about
the hazards of working with ultraviolet (UV) light sources. The UV light
sources are used to expose Graphic Arts film, proofing materials, and
conventional printing plates. The lights are mounted about 40" above a
vacuum frame which holds the photosensitive material in contact. A few of
the larger manufacturers of the exposure sources are Burgess, Olec, and
Douthitt. During an exposure, an operator will usually close a curtain to
sheild most of the light. However, a large majority of my customers don't
use the curtains or don't have curtains surrounding their light sources. I
believe there is a significant amount of UV light emitted from the lamp,
and are concerned about the health hazards of long term exposure (an
operator who exposes material 8 hrs./day, 5 days/week). Any help you can
give me in tracking down some data on this topic would be greatly
appreciated. Talk to you soon.
