A federal regulation designed to protect against the risk of exposure to lead dust and chips from lead-based paint and other lead-based coatings disturbed by renovation activities will take effect beginning in April 2010.

Contractors performing renovation, repair and painting projects that disturb lead-based paint in homes, child care facilities and schools built before 1978 must be certified and must follow specific work practices to prevent lead contamination.  This includes wood flooring contractors.

In order to understand your potential obligations under this new rule, refer to http://www.epa.gov/lead/pubs/renovation.htm
