The UV levels are highest in spring and summer between 11 a.m. and 4 p.m. At noon on a clear summer day, for example, it can take only 15 minutes to cause a sunburn on unprotected fair skin.
To reduce the exposure of workers to ultraviolet rays while working in direct sunlight when UV levels are high, the following precautions are recommended:
