After permeation into the skin, a few chemicals act as irritants upon absorption of UV light. In the occupational setting, PICD is most likely to be seen among construction or railroad workers who have handled creosote or among food preparation workers who have handled lime, celery, parsnip, or figs. After skin contact with creosote, PICD may be observed immediately after exposure to light. Workers handling the dyes eosin, methylene blue or disperse blue 35 are also at risk for PICD. [Marks, p. 201-3] "Tar smarts" is a form of photoirritant dermatitis caused by coal tar pitch derived from coal, not by asphalt derived from petroleum. Workers complain of burning of the skin starting about one hour after exposure to pitch and sunlight. Erythema and blistering may ensue. Preventive measures include wearing long-sleeve shirts, gloves, and sunscreens. [Kanerva, p. 1092] |
