The damaging effect of ultraviolet rays on human beings is well known. People who get too much direct exposure to the sun can develop such maladies as skin cancer, premature wrinkling, and eye damage, just to name a few. But people can generally find shelter out of the sun when it gets too hot. But consider expensive heavy equipment that can’t be stored in a shelter. Repeated exposure to UV rays will cause damage to heavy equipment that goes beyond the merely cosmetic. In fact, excessive UV rays can cause damage that could make the equipment non-functional.
