The characterization of a black light device: a hazard evaluation process

The results of an occupational hazard evaluation process to assess the potential ultraviolet radiation exposure from broad-band sources of optical radiation are compared with the American Conference of Governmental Industrial Hygienists (ACGIH) guidelines for occupational exposure to ultraviolet radiation. A black light fluorescent lamp device, evaluated according to these criteria, exceeded the ACGIH-TLV for UVA and UVB. Design modifications resulted in acceptable occupational exposure levels without compromising the performance of the device.
