Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

What item is not required for using during dust sampling in risk assessment?

1. Disposable gloves

2. Disposable shoe covers

3. Lead dust wipes that contain lanolin

4. Hard plastic centrifuge tubes

The correct answer is: Lead dust wipes that contain lanolin

In the context of dust sampling during risk assessments for lead-based paint, the primary focus is on the equipment and materials necessary to accurately collect and analyze samples. Disposable gloves are essential to prevent contamination of both the samples and the individual conducting the sampling. Disposable shoe covers help to maintain a clean environment by preventing the transfer of lead dust from footwear, thus ensuring accurate sample collection. Hard plastic centrifuge tubes are also critical for storing and transferring collected dust samples to the lab for analysis. They provide a stable and contamination-free environment for the samples during transit. On the other hand, lead dust wipes containing lanolin are not a necessary component for dust sampling in risk assessment. The primary purpose of lead dust wipes is to collect and quantify lead dust from surfaces, but during the actual dust sampling process for risk assessment, specific sampling tools and materials are preferred to ensure proper techniques and standards. Using wipes containing lanolin could potentially interfere with analysis due to the sticky nature of lanolin, thus making them less suitable for this particular task.
