CDPH Lead Inspector/Assessor California State Practice Exam

What is the maximum allowable HEPA vacuuming rate for wall-to-wall carpets that cannot be folded?

1. 1 minute per 10 square feet

2. 2 minutes per 10 square feet top-to-bottom

3. 2 minutes per 10 square feet from side-to-side

4. 2 minutes per 10 square feet from side-to-side then 2 minutes per 10 square feet top-to-bottom

The correct answer is: 2 minutes per 10 square feet from side-to-side then 2 minutes per 10 square feet top-to-bottom

The maximum allowable HEPA vacuuming rate for wall-to-wall carpets that cannot be folded involves a thorough cleaning approach, ensuring that all areas are effectively addressed. The chosen answer highlights the necessity of a systematic technique by allowing for vacuuming from different orientations. By dividing the vacuuming process into two parts—first from side-to-side and then from top-to-bottom—this method ensures comprehensive coverage of the carpet surface. This thorough method is crucial for effective lead dust remediation because it maximizes the potential of the HEPA vacuum to capture contaminants in various orientations, especially in areas where dust and debris may settle differently. This approach is aligned with best practices for lead-safe work practices recognized in regulations, which prioritize thoroughness and effectiveness in cleaning, especially in environments where lead may be present. Ensuring that the carpet is vacuums systematically from two different angles enhances dust removal efficacy, making it a sound choice for a maximum allowable vacuuming rate.
