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

When should interim controls not be recommended?

1. When there are composite samples taken from multiple sources

2. In building fountains

3. In well-maintained play areas

4. When the risk assessor is licensed

The correct answer is: In building fountains

Interim controls are typically temporary measures aimed at reducing exposure to lead hazards before more permanent solutions are implemented. In the context of the provided question, interim controls may not be suitable for specific situations that present unique risks or challenges. Fountains, particularly in buildings, can be considered high-risk areas due to the combination of water and potential lead-contaminated surfaces. Water features may present continuous exposure to lead, especially if the components are made of lead-containing materials or if the water is contaminated. In these cases, relying on interim controls would not adequately mitigate the risk of lead exposure, since the water can constantly interact with contaminated surfaces. Therefore, permanent solutions would be more appropriate to ensure that the lead hazard is fully addressed. The other situations mentioned do not inherently carry the same level of immediate risk associated with lead exposure, allowing for varying degrees of interim control application. For instance, composite samples or well-maintained play areas might have more manageable lead levels that can be addressed with interim measures, while being licensed as a risk assessor provides professional credentials but does not dictate the appropriateness of interim controls in specific hazardous settings.
