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

What must be included in the supplies for dust wipe sampling by a Risk Assessor?

1. Lead dust wipes with lanolin

2. Reusable containers

3. Non-sterilized gloves

4. Disposable shoe covers

The correct answer is: Non-sterilized gloves

In the context of dust wipe sampling, non-sterilized gloves are crucial for protecting both the assessor and the sampling environment from contamination. Wearing gloves during the sampling process helps prevent the transfer of lead and other contaminants from the assessor's hands to the samples, ensuring the integrity of the dust wipes. This practice is essential for obtaining accurate and reliable results when assessing lead levels in the environment. While other items may also be relevant for various stages of the sampling process, the use of non-sterilized gloves specifically addresses the need for personal protection and contamination control during the actual sampling phase. This requirement ensures that the samples collected reflect the true lead dust levels present in the environment, which is a vital aspect of risk assessment in homes and buildings where lead-based paint may be an issue.
