To the extent possible, job tasks should be located indoors or under shade when exposure to solar radiation presents a risk. Work that must be conducted outdoors should be scheduled to avoid sun exposure during the period of highest solar irradiance, two hours before to two hours after solar noon.

In many occupations, however, outdoor work is unavoidable, and the only practical means of controlling exposure is the use of skin and eye protection. Protective clothing should be chosen to provide an adequate protection factor and the best coverage possible. Acceptance of protective clothing by the workers is also an important consideration (67), however, and may need to be balanced against the level of protection offered by different styles and fabrics. Sunscreens should be used on those parts of the body that are not protected by clothing but not as a substitute for wide‐brimmed hats and protective clothing. According to the American Academy of Dermatologists, sunscreens should have a minimum SPF of 30, and provide protection from UV‐A as well as UV‐B radiations (68).
