With the enactment last spring of the EPA's Renovation, Repair, and Painting (RRP) rule, contractors are facing a number of new requirements, one of which is to use a HEPA vacuum for cleanup whenever lead-based paint is disturbed. The rule also says that HEPA vacs need to be used with tools that sand or grind lead paint. Contractors should assume that any home built before 1978 contains lead paint unless testing shows it does not.
