Environmental Protection Agency (EPA) Lead Risk Assessor Practice Exam

What condition is indicated if more than 2 ft² is damaged in dust wipe sampling?

1. Intact

2. Fair

3. Poor

4. Acceptable

The correct answer is: Poor

When evaluating the results of dust wipe sampling, the condition of the surfaces being tested is crucial for determining potential lead exposure risks. A finding of more than 2 square feet of damaged area indicates a significant level of deterioration or disruption of lead-based paint or materials. This level of damage often suggests that lead dust may be present in the environment, posing a higher risk for lead exposure, especially in residential settings. When assessing risk, categorizing the condition helps in making informed decisions about necessary remediation or interventions. A designation of "poor" is appropriate in this context because it clearly reflects a concerning state of the painted surfaces. The amount of damage implies that the materials are not only compromised but also likely contributing to potential lead dust contamination in the living space. The other classifications, such as "intact," "fair," and "acceptable," represent varying levels of condition that do not accurately align with the extent of damage indicated by the presence of more than 2 square feet of compromised material. In situations with significant damage to surfaces, especially in relation to lead exposure, it is essential to identify the condition correctly as 'poor' to prioritize health and safety measures.
