Children can become lead poisoned when they swallow lead dust or paint chips. Lead poisoning can damage a child’s brain, nervous system, kidneys and red blood cells. Even at low levels, lead in a child’s blood can cause learning and behavioral problems. The Lead Law requires compliance in homes built before 1978 where a child less than six years old lives. In 1994 changes were made to the Lead Law to make deleading easier and less costly. These changes included the approval of special encapsulant products for deleading. What is an encapsulant? An encapsulant is a liquid coating that dries to form a long-lasting barrier over lead paint. Paint is not an encapsulant. In Massachusetts, only the products tested by David Litter Laboratories and approved by the Childhood Lead Poisoning Prevention Program, CLPPP, can be used to delead. These products have this seal on them: Who can apply an encapsulant? Homeowners or a person hired by the owner (agent) can apply the encapsulants as long as he or she completes the training described in this booklet. Agents must be at least 18 years old. Licensed Deleaders and Moderate risk Deleaders (licensed lead safe renovators with an additional 4 hour moderate risk training and MR license) can also apply encapsulants according to this training. Types of Surfaces that May be Encapsulated
