CDPH Lead Inspector/Assessor California State Practice Exam

According to the EPA, what is the percentage chance of homes built prior to 1940 containing lead-based paint?

1. 56%

2. 86%

3. 76%

4. 45%

The correct answer is: 86%

The correct percentage of homes built prior to 1940 containing lead-based paint is 86%. This statistic underscores the fact that lead-based paint was commonly used in residential properties before the ban in the late 1970s. Since many homes constructed before 1940 are likely to have been painted with lead-based paint, the likelihood is considerably high, indicating a significant risk for lead exposure in these older homes. The EPA has established this percentage based on historical data and research regarding the prevalence of lead paint in homes, making it essential for lead inspectors and assessors to be aware of this risk when evaluating properties built during that time. Understanding this statistic is crucial for implementing appropriate lead hazard assessments and ensuring the safety of residents in such homes. This knowledge also drives regulations and guidelines aimed at protecting public health from the risks associated with lead exposure.
