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

What is the maximum acceptable contamination level in wipes, according to the guidelines?

1. 10 ug/wipe

2. 5 ug/wipe

3. 1 ug/wipe

4. 20 ug/wipe

The correct answer is: 5 ug/wipe

The maximum acceptable contamination level in wipes, as outlined in the guidelines, is 5 micrograms per wipe. This standard is based on risk assessments and ensures safety regarding lead exposure, especially in environments where children may be present or where lead-based paint hazards are a concern. Using a limit of 5 micrograms helps to minimize potential lead exposure through contact with surfaces where lead dust may accumulate. This threshold helps to establish a balance between practicality in cleaning and the need for protecting health, particularly in residences and facilities where lead-based paint is a potential hazard. The rationale for this specific figure aligns with scientific understanding of lead toxicity and the need for preventive measures in environments where lead might be present. It's an important part of lead risk assessments and remediation efforts aimed at ensuring that surfaces are adequately clean and safe, especially for vulnerable populations.
