Surface PreparationPregunta 5 de 100
Which work practice is REQUIRED by the EPA RRP Rule when disturbing lead-based paint in a pre-1978 home?
a.Dry-sanding to keep dust airborne for easier cleanup
b.Using an open flame torch to burn off the paint
c.Containing the work area with plastic and cleaning with HEPA vacuuming and wet methods
d.Sweeping debris into the yard for disposal
Explicación
Lead-safe practices require containing the area with plastic sheeting, minimizing dust, and cleaning with HEPA vacuums and wet wiping. Open-flame burning and uncontrolled dry sanding are prohibited because they generate hazardous lead dust or fumes. A cleaning verification step confirms the area is safe before reoccupancy.
