In what area should lead testing be prioritized in older homes?

Lead testing should be prioritized in areas where children are most likely to come into direct contact with lead-based materials. Windows, doors, and surfaces that children frequently touch are critical areas because lead can be found in the paint of these components, especially in homes built before 1978 when the use of lead-based paints was banned for residential properties. Children often interact with these surfaces through activities like playing, crawling, or resting their hands, which increases their risk of lead exposure.

Prioritizing these areas for lead testing helps identify potential hazards in places where children could inadvertently ingest lead dust or chips. This targeted approach is essential for ensuring child safety and minimizing exposure risks in environments where they spend a significant amount of time. In contrast, while roofing and insulation materials may contain lead, they are typically not areas that children frequently interact with. Additionally, focusing solely on basements or garage spaces, or limiting testing to kitchen areas, would fail to consider the broader impact of lead exposure in areas where children's activities occur most. Ensuring comprehensive testing in high-contact areas is critical for effective lead hazard management.
