CDPH Lead Inspector/Assessor California State Practice Exam

What percentage of homes built between 1940-1959 are likely to have lead-based paint, as per the EPA?

1. 50%

2. 66%

3. 75%

4. 40%

The correct answer is: 66%

The correct answer reflects that approximately 66% of homes built between 1940 and 1959 are likely to contain lead-based paint, according to the Environmental Protection Agency (EPA). This is grounded in historical practices, as lead was commonly used in paint until it was banned for residential use in 1978 due to safety concerns over lead exposure, particularly for children and pregnant women. Homes constructed during this period often utilized lead-based paint for its durability and ease of application. In the context of lead exposure risks, this knowledge is crucial for inspectors and assessors, as homes built during these years are more likely to pose potential health hazards associated with lead. Understanding the statistical likelihood helps professionals prioritize inspection efforts and implement necessary lead hazard interventions in older homes, thus safeguarding public health.
