CDPH Lead Inspector/Assessor California State Practice Exam

How many paint-chip samples are required for each testing combination?

1. One

2. Two

3. Three

4. Five

The correct answer is: One

In lead-based paint testing, the requirement is to collect one paint-chip sample for each distinct testing combination. This means that if you have different colors, surfaces, or types of paint, each unique combination would necessitate one sample to accurately assess lead content. Collecting just one sample per combination simplifies the testing process while still providing a representative analysis of the lead levels present in the various painted surfaces. It also aligns with standard testing protocols designed to evaluate the hazards associated with lead-containing materials without overcomplicating the collection process or using excessive resources. This method ensures that the findings are both relevant and effective in identifying potential lead exposure risks, which is critical for undertaking the appropriate mitigation measures.
