What is the primary concern for buildings constructed before 1978 in relation to lead?

The primary concern for buildings constructed before 1978 in relation to lead is the presence of lead-based paint. This is a crucial aspect because homes built during this time often utilized lead-based paint for its durability and moisture resistance. When the paint deteriorates, it can become a source of lead dust or lead-contaminated chips, posing significant health risks, particularly to children and pregnant women.

Lead poisoning from lead-based paint exposure has been well documented, leading to various health issues including developmental delays, learning difficulties, and other serious health concerns. Because of these dangers, the federal government banned the use of lead-based paint in residential properties in 1978, making awareness and remediation of this hazard critical in older buildings.

While lead pipes, contaminated soil, and old electrical systems may present concerns, the predominant issue for buildings prior to 1978 is indeed the lead-based paint, underscoring the focus on this hazard in lead inspections and assessments.
