Giải thích
Homes built before 1978 are presumed to contain lead-based paint. Cal/OSHA and lead-safe rules require presuming lead is present, using trained workers, containment, wet methods or HEPA controls, and proper waste disposal. Option c reflects this. Assuming it is clean (a), dry sanding (b) which spreads lead dust, and leaving PPE to individual choice (d) all expose workers and occupants to lead poisoning.
