Topeka ? New rules on lead-based paint in Kansas housing go into effect this week.

The regulations are meant to minimize the risk of lead poisoning to residents and to people who work with paint.

The Kansas Department of Heath and Environment administers the new rules, which take effect Friday.

They apply to contractors, property managers and others who disturb painted surfaces in homes, apartments and child-occupied structures built before 1978.

Before starting renovations, those working on surfaces covered with lead paint will have to receive special training, certification and licensing.
