CDPH Lead Inspector/Assessor California State Practice Exam

Which material is NOT classified as a substrate in lead inspection?

1. Concrete

2. Glass

3. Wood

4. Metal

The correct answer is: Glass

In the context of lead inspection, a substrate refers to the surface or material upon which lead-based paint may reside or interact. Common substrates in this context include concrete, wood, and metal, as these materials are often used in homes and buildings where lead-based paint could have been applied. Glass, on the other hand, is typically not classified as a substrate for lead inspection purposes. This is primarily due to the fact that lead-based paints are not applied to glass surfaces. Instead, glass surfaces are often just kept clean and free of paint, making them not a focus for lead inspections aimed at identifying potential lead hazards. Additionally, glass does not hold paint in the same manner as the other materials, further distinguishing it from the categories where lead exposure poses a concern. Understanding the types of surfaces that are relevant to inspections is crucial for lead abatement professionals, as it guides them in determining where lead exposure risks exist and what materials need to be assessed or treated.
