Sources Of Lead In The Workplace

Workers can be exposed to lead hazards associated with different types of buildings. Whether they are old or new, all buildings have some potential for exposure to lead. For example, old buildings usually contain lead-based paint that is often deteriorated. In addition, lead pipes and solder are used in the plumbing systems, which can result in contaminated dust, soil and water. New buildings can have water supplies and plumbing that use lead piping and solder (including water coolers). Industrial facilities can be contaminated from processes such as smelting, foundries, welding and manufacturing.

Some of the leading causes of lead exposure in the workplace include:

  • Lead-based paint: The potential for contamination and exposure from lead-based paint is particularly severe when paint is deteriorating and loose, flaking or peeling. Uncontrolled renovation, repair, and demolition that inadvertently affects lead-based paint can result in contamination and injury to building occupants, workers and the general public.

  • Drinking water: Significant amounts of lead are rarely found in public drinking water at its source, but water may become contaminated as it moves through the distribution system to and within buildings. Water also may be contaminated by lead leaching from lead pipes or service connectors, from lead-based solder used on copper pipes, from brass fixtures, or from lead-lined tanks in water coolers.

  • Air pollution: Currently, the greatest sources of leaded air pollution are industrial emissions from metal smelters, refineries and ash generated by incinerators. Contributing to the problem is ash that is often hauled in open trucks to disposal facilities.

  • Soil and dust: Sources of lead in soil and dust include industrial emissions, pesticides, spent casing from shooting ranges, and flaking, chipping, or weathering paint. The improper removal and disposal of lead-based paint during the renovation and repair of buildings and other structures also continues to be a serious source of exposure.
