CDPH Lead Inspector/Assessor California State Practice Exam

The correct answer indicates that there is a 25% chance of lead-based paint being present in homes constructed between 1960 and 1978. This is significant because homes built during this time frame are often associated with the transition period regarding the use of lead in residential paints. While the use of lead-based paint was banned in residential properties in 1978, many homes built before this ban still may contain lead-based paint. The 25% figure is derived from statistical studies and surveys conducted regarding residential properties, which have identified that approximately one in four homes built in that era may have lead-based paint. This awareness is crucial for lead inspectors and assessors, as it emphasizes the need for proper risk assessments and lead-paint remediation strategies when inspecting homes from this period. Understanding the prevalence of lead-based paint in homes built between 1960 and 1978 helps ensure that public health measures are correctly targeted, ultimately reducing the risk of lead exposure among residents, especially young children and pregnant women.
