What is Lead-Based Paint and What is a Lead Hazard?
Lead-based paint – The Federal definition is at least 1 milligram per square centimeter of lead on a surface or at least 0.5 percent by weight. A lead-based paint hazard is a condition that causes exposure to lead sufficient to cause adverse human health effects. Lead hazards include: • Deteriorated lead-based paint. As paint ages or is damaged, it deteriorates and may create hazardous conditions including lead-based paint chips, and lead-contaminated dust and soil. • Friction, impact and chewable surfaces. Certain surfaces are subject to damage and, therefore, likely to generate lead-contaminated dust, soil, and paint chips. These include • surfaces subject to friction or abrasion such as stair tread and window sashes, • surfaces subject to repeated impacts such as door frames, and • surfaces that are available to children to mouth or chew such as window sills and door frames. • Lead-contaminated dust. Lead-contaminated dust is dust with lead concentrations that exceed Federal standar
