Lead Hazards

Lead-based paint on walls, trim, doors, and windows in pre-1978 homes. Lead dust from deteriorating paint and renovation activities. Lead in soil around foundations from exterior paint and leaded gasoline. Lead pipes and plumbing solder in pre-1986 homes. Imported ceramics, antique furniture, and other consumer products.

Pre-1940 homes have 87% likelihood of lead paint. 1940-1959 homes have 69% likelihood. 1960-1977 homes have 24% likelihood. Post-1978 homes are low risk as lead paint was banned for residential use.

Intact paint is low hazard but must be monitored. Deteriorating paint with peeling, chipping, or flaking is high hazard requiring remediation. Friction and impact surfaces like windows and doors generate ongoing lead dust.

Children under 6 are most vulnerable with risk of developmental delays, learning difficulties, and behavioral problems. Adults may experience high blood pressure, kidney damage, and reproductive issues. Even low levels of lead exposure can cause irreversible harm. No safe level of lead exposure has been identified.

XRF analyzers provide instant non-destructive results. Paint chip laboratory analysis for confirmation. Dust wipe testing for surface contamination levels. Soil testing around foundation and play areas. Water testing for lead in plumbing systems.

Component replacement removes lead-painted items entirely. Encapsulation coats surfaces with specialized sealant. Enclosure covers lead surfaces with new materials. Paint removal using chemical strippers or controlled methods. Each method has specific EPA and HUD requirements.

EPA RRP Rule requires certified contractors for renovation in pre-1978 homes. HUD Lead Safe Housing Rule for federally assisted housing. Seller disclosure requirements for known lead paint. EPA Section 402 certification for abatement professionals. State-specific licensing requirements for lead inspectors and abatement workers.

Contain work area with plastic sheeting. Minimize dust creation during renovation. HEPA vacuum all surfaces after work. Wet methods for sanding and scraping. Prohibited practices include open flame burning, power sanding without HEPA, and dry scraping large areas. Workers must wear respirators and protective clothing.

Regular inspection of painted surfaces for deterioration. Wet cleaning to control lead dust on floors and windowsills. Maintain intact paint in good condition. Address moisture issues that cause paint deterioration. Regular hand washing especially for children in older homes.
