De minimis levels safe work practices during stabilization or abatement apply when the area disturbed exceeds which thresholds?

• A. Exterior 40 sq ft, interior 4 sq ft, or 20% of a small component
• B. Exterior 40 sq ft, interior 4 sq ft, or 50% of a small component
• C. Exterior 20 sq ft, interior 2 sq ft, or 10% of a small component
• D. Exterior 20 sq ft, interior 2 sq ft, or 10% of a small component

Answer: (D)

De minimis levels define the small disturbance thresholds where you can use basic, lead-safe practices instead of full containment. If the area you disturb during stabilization or abatement stays within those limits—exterior area up to 20 square feet, interior area up to 2 square feet, or disturbance of no more than 10% of a small component—you can apply de minimis safe-work practices. These thresholds acknowledge that very small amounts of work pose lower risk and allow simpler procedures while still protecting occupants and workers. If you exceed any of these limits, more stringent lead-safe practices and containment are required to manage the hazard. The thresholds given are exterior 20 sq ft, interior 2 sq ft, or 10% of a small component.
