#136 Lead

Occupational exposures to lead can occur in construction activities, such as plumbing system retrofits; the spraying, removal, or heating of paint that contains lead; and the welding, cutting, and grinding of lead-containing construction materials.

Occupational lead exposures can affect workers as well as family members and friends who come in contact with the “take-home” lead on worker’s clothing, hair, hands, etc. The toxic effects of lead on the human body have been well documented and included damage to the kidneys, brain, and reproductive organs that, in turn, causes the loss of kidney function, sterility, decreased fertility, and birth defects and mental retardation in offspring.
