CDPH Lead Inspector/Assessor California State Practice Exam

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

1. 1 minute per 10 ft2

2. 2 minutes per 10 ft2

3. 3 minutes per 10 ft2

4. 4 minutes per 10 ft2

The correct answer is: 2 minutes per 10 ft2

The maximum rate for HEPA vacuuming wall-to-wall carpets that cannot be folded over is set at 2 minutes per 10 square feet. This standard is established to ensure that the vacuuming process is thorough, particularly in areas where lead dust may have settled. The designated time allows for sufficient suction and filtration efficiency to capture lead particles effectively from the carpet fibers. Understanding the importance of this time frame is crucial for lead inspectors/assessors, as it emphasizes the need for diligence when dealing with lead hazards. Lead dust can adhere to surfaces, and without adequate vacuuming techniques and appropriate time, residual contamination can remain, posing health risks. This rate is particularly relevant in residential or commercial settings where lead may have been present, ensuring that carpets are cleaned properly to minimize exposure. Hence, maintaining this standard helps ensure compliance with health and safety regulations in lead hazard management.
