Contractors will have to train workers to follow “lead-safe work practice standards” when renovating or repairing older dwellings that house children or pregnant women, according to new standards introduced Monday by the U.S. EPA. The new requirements are an attempt to keep lead out of the bloodstreams of babes, as structures built before 1978 are likely to contain lead-based paint. The standards will go into effect in 2010. By the by, the EPA was supposed to adopt lead-safe regulations for renovations in October of 1996. My, how the time flies.
