Lead-Based Paint
Most houses and buildings built before 1950 have had lead-based paint
applied to the interior or exterior surfaces. In most cases, lead paint
of this era contained up to 40% lead by weight. Paints made between
1950 and 1978 usually contained smaller amounts of lead. Lead paint
that is in poor condition is known to be a potential hazard to small
children and pregnant women.
In 1993, increasing concerns about exposure to lead paint during construction
and renovation activities prompted OSHA to revise their Lead In Construction
Standard to be more protective of workers engaged in such activities.
The standard provides guidelines and work practices to minimize the
generation and migration of lead-containing dust, establishes a permissible
exposure limits for inhalation, and biological monitoring criteria.
