Clean-up and renovation:
Natural disasters such as tornadoes, hurricanes or floods often result in the need for emergency renovations to damaged homes and other structures. When common renovation activities like sanding, cutting, and demolition occur in structures that contain lead-based paint, they can create lead-paint hazards, including lead-contaminated dust an paint flakes. Lead-based paint dust and debris are hazardous to everyone - adults, particularly pregnant women, and children.
