        In summer, workers should avoid unnecessary exposure to the sun, especially midday between 11 am and 16 pm, when solar radiation is a maximum intensity. Wherever possible, it is better to schedule the execution of works outdoors in early morning or late afternoon, and work in the shade. Umbrellas and parasols can protect against direct sunlight. In addition, since water, white sand, concrete, snow and ice can reflect about 10 to 85 per cent of solar ultraviolet radiation, it may be necessary to use additional protection against exposure indirectly created by the reflected rays.

        Despite its rarity, malignant melanoma is the most dangerous of all skin cancers. It often appears as a mole or pigmented spot that suddenly starts to bleed or change color, shape or texture. Without early treatment, malignant melanoma is usually spread. The exact nature of the link between melanoma and sunlight is not completely understood. However, it seems that among people who do not usually exposed to sunlight, the risk of malignant melanoma is increased after brief exposure (intermittent) to intense sunlight. Malignant melanoma can be treated and cured if diagnosed early. However, if treatment is initiated at an advanced stage of disease, this cancer is often deadly.

        The skin exposed to UVA or UVB is two to three days before staining. This type of tanning said "delayed", may persist for weeks or months, and is maintained through repeated exposure to the sun. During the tanning process delayed, the skin increases its production and distribution of dark pigment, furthermore, the skin thickens. These changes may occur after a sunburn or occur gradually over a long period of repeated brief exposures to sunlight.
