What is the purpose of post-hazard control clearance sampling?

• A. To assess general building aesthetics after work.
• B. To determine that the hazard control strategy has been conducted, the area is safe for unprotected workers to enter, and safe for residents and young children to live in.
• C. To measure energy efficiency improvements.
• D. To document the contractor's compliance with permit requirements only.

Answer: (B)

Post-hazard control clearance sampling verifies that the hazards have been adequately controlled and that the space is safe for re-entry and occupancy. It confirms that the hazard control work was completed and that the area meets the lead-dust clearance standards so unprotected workers can return to the space and residents, including young children, can live there safely. The process involves collecting dust/wipe samples from key surfaces and comparing the results to regulatory clearance limits; if the results exceed those limits, additional cleanup is needed until the area meets safety criteria. This isn’t about aesthetics, energy efficiency, or merely documenting permit compliance.
