EPA Lead Supervisor Course Practice Exam

Interim control measures are designed to

Permanently eliminate LBP hazards. Permanently remove soil containing lead. Temporarily reduce human exposure to LBP hazards. Ensure continuous occupancy without restrictions.

Correct Answer:

Temporarily reduce human exposure to LBP hazards.

Explanation:

Interim control measures are temporary steps to lower people’s exposure to lead-based paint hazards while long-term remediation is planned or carried out. They focus on limiting contact with lead dust and chips, and preventing dust from spreading, so occupants aren’t exposed during the interim period. These are not meant to permanently eliminate the hazard or remove soil—that requires permanent abatement or remediation—and they aren’t about allowing unrestricted occupancy; if needed, access and activities are temporarily restricted to reduce exposure. Examples include isolating the work area, sealing or enclosing hazards, wet cleaning, and using barriers and HEPA cleaning to control dust.
