Before disturbing painted surfaces during a repaint in a home built before 1978, a contractor must MOST importantly follow what requirement?
a.Only wear a dust mask if the owner requests it
b.Apply paint directly over the old coating with no preparation
c.Use lead-safe (RRP) work practices for potential lead-based paint
d.Pressure-wash all surfaces into the storm drain
Giải thích
Pre-1978 homes may contain lead-based paint, so disturbing painted surfaces requires certified lead-safe (Renovation, Repair and Painting) practices to contain and clean up dust. Skipping protection, painting over without prep, or washing debris into a storm drain all violate lead-safety and environmental rules.
