What materials are typically assessed during a lead inspection?

Lead inspections are primarily focused on identifying materials that are known to harbor lead or have the potential for lead exposure. The materials typically assessed during a lead inspection include paint, dust, and soil.

Lead-based paint is a significant concern, especially in homes built before 1978 when the U.S. banned the use of lead in residential paint. This paint can deteriorate over time, creating lead dust that children can ingest. Dust is sampled because it can settle on surfaces and be easily inhaled or consumed by children, particularly those who are more prone to putting objects in their mouths. Soil is also tested because it can be contaminated by lead from peeling paint or environmental sources and can pose a risk, especially in outdoor play areas.

Other materials, such as wood, plastic, glass, metal, carpet, and fabric, are not typically sources of lead and therefore are not the primary focus of inspections aimed at identifying lead hazards. These materials may not hold or transfer lead in ways that pose a significant risk to health. Therefore, assessing paint, dust, and soil is critical in determining the potential for lead exposure in a building or environment.
