A contractor is renovating a 1972 Oregon duplex and will disturb 45 square feet of painted trim. Which statement about lead-safe work practices is correct?
Correct Answer
B) Must contain work area and use HEPA vacuum
Work in pre-1978 housing disturbing more than 6 sq ft requires full RRP compliance including containment, HEPA vacuum, and certified renovator supervision.
Why This Is the Correct Answer
The correct answer is B (must contain work area and use HEPA vacuum). The EPA's Renovation, Repair, and Painting (RRP) Rule applies to pre-1978 housing when more than 6 square feet of painted surface is disturbed indoors. A 1972 duplex predates 1978, and 45 sq ft exceeds the 6 sq ft threshold, triggering full RRP compliance: work area containment, HEPA vacuuming, and certified renovator supervision.
Why the Other Options Are Wrong
Option A: Can use standard plastic sheeting for containment
Standard plastic sheeting alone is insufficient. RRP rules require a specific containment protocol — not just any plastic sheeting. The work area must be properly sealed to prevent dust migration, and HEPA vacuuming is also required.
Option C: No special precautions required due to small area
No special precautions required is incorrect and dangerous. The small area exemption only applies when less than 6 square feet of painted surface is disturbed indoors. At 45 square feet, full RRP compliance is mandatory.
Option D: Only need to wet surfaces before scraping
Wetting surfaces before scraping alone is insufficient. While wetting is a component of some lead-safe practices, it does not satisfy RRP compliance requirements on its own. Containment and HEPA vacuuming are also required.
Memory Technique
Remember the RRP triggers: Pre-1978 housing + more than 6 sq ft interior (or 20 sq ft exterior) = full RRP compliance required. Think '6 square feet = lead-safe mandate kicks in.' HEPA + contain = the two must-dos.
