In general, there is evidence that excessive ultraviolet radiation (UVR) exposure from sunlight, both in recreational and occupational settings, can have deleterious health effects, including increasing the risk of skin cancers. However, data specifically dealing with the risks of skin cancer in lifeguards are not available. Of concern is that: 1. outdoor workers may receive up to six to eight times the dose of UVR compared to indoor workers; and, 2. rates for some skin cancers among outdoor workers have been associated with cumulative2 UVR exposure. Skin cancers are preventable by reducing the exposure to the UVR from sunlight. In 1972, the National Institute for Occupational Safety and Health (NIOSH) issued criteria for a recommended standard entitled Occupational Exposure to Ultraviolet Radiation which advised that ". . . susceptible persons working outside in strong sunlight should be protected."3 But there are currently no State or Federal requirements providing outdoor workers with shelter, protective clothing/hats, sunscreens, or sunglasses. Studies have shown an association between excessive sun exposure and both premature skin aging and skin cancer.
