Lead is a naturally occurring element that is a dull silver bluish color. It is dense, malleable, resists corrosion, and has a low melting point. Lead is sometimes found free in nature but usually combines with other elements to form lead compounds. Due to the high density of lead, it is used as a shield from the radiation given off by X-ray machines and nuclear reactors. Its resistance to corrosion makes lead a good candidate for lining containers and tanks that hold corrosive materials such as acid. This training will cover a brief history of lead usage, and will also describe the potential dangers and preventive measures for dealing with lead containing materials.
