Contractors, painters and landlords now face state fines if they don't take certification training and take proper precautions before working on walls, windows or doors that are covered with lead paint.
Published reports reveal that state regulations have been in effect since April last year. Officials have held off on the fines, giving contractors and landlords plenty of time to become aware of the new rules and to comply.
But since last week, those who don't observe the rules have faced fines that can reach $5,000 per incident.
The rules don't apply to residents who do the work themselves.
Lead paint is common in older buildings, and renovations often stir up dust and paint chips that children can swallow or inhale. The lead can cause brain damage.
