Where personnel may be exposed to levels of radiation that clearly exceed the
MPE for the skin, particularly in the ultraviolet, the LSO shall recommend or
approve the use of protective clothing. Where personnel may be subject to chronic
skin exposure from scattered ultraviolet radiation, as may occur during excimer
laser processing, skin protection should be provided even at levels below the
MPE for the skin. Consideration should also be given to the use of fire resistant
material when using Class IV lasers.
