CDPH Lead Inspector/Assessor California State Practice Exam

Which of the following is considered Category II waste?

1. Excavated lead-contaminated soil

2. Concentrated lead waste

3. Painted architectural components

4. Non-hazardous construction waste

The correct answer is: Painted architectural components

The correct choice regarding Category II waste is painted architectural components. This classification is important in the context of lead-related regulations and waste management. Painted architectural components are considered Category II waste because they may contain lead-based paint, which poses a risk of lead exposure, especially in environments where such materials are demolished or deteriorating. The presence of lead in paint mandates specific handling and disposal procedures to mitigate environmental and health risks. In contrast, excavated lead-contaminated soil and concentrated lead waste typically fall into more hazardous categories due to their higher levels of lead contamination, requiring stricter handling protocols. Non-hazardous construction waste is not classified as Category II because it does not have the potential for lead exposure and requires different management strategies entirely. Therefore, painted architectural components occupy a middle ground where they require careful oversight due to their potential lead content.
