Childhood Lead Prevention Program: Parent Information
Where does lead come from? How are children exposed?
Lead is a common environmental contaminant because in the past, lead was widely used as an ingredient of house paint and gasoline for motor vehicles, and also due to the fact that lead cannot biodegrade. Beginning in the 1950s, some U.S. paint manufacturers began to voluntarily reduce the percentage of lead in residential paints, and in 1978, the Federal government eventually banned the manufacture of residential lead paint. Leaded gasoline for motor vehicles was no longer available in the United States after December 31, 1995.
In San Francisco, City agencies have the right to assume that all pre-1979 buildings have a lead paint history. When paint on pre-1979 buildings is damaged by a lack of maintenance or disturbed by renovation activities, lead dust is created and deposited on the home's interior and exterior surfaces, as well as the soil surrounding the home.
These conditions are called lead hazards. Young children are much more likely to be exposed to lead hazards because they touch lead-contaminated surfaces and then put their hands in their mouths. In addition, children's bodies absorb more lead than adults bodies do because they are still growing.
Why and when should children be tested for lead?
Lead is a poison that may seriously affect health, learning ability and behavior. Only a blood lead test can tell you if your child has been exposed.
If your child spends time in any setting built before 1979, have your child tested for lead at regular checkups when he or she is 1 year old, and again when he or she is 2 years old. If your child has not been tested at 1 and 2 years of age, have him or her tested at least once before 6 years old.
What do blood lead test results mean?
What are lead hazard violations? What can parents do to prevent exposure?
The San Francisco Childhood Lead Prevention Program provides services and information to identify lead hazards and prevent children's exposure to lead.
- If a child under six years old can be exposed to lead hazards, it is considered a violation of the San Francisco Health Code.
- If renovation and repair work on a pre-1979 building is not properly contained, and all dust and debris generated subsequently cleaned up, it is considered a violation of the San Francisco Building Code.
- The State and Federal government have additional laws requiring lead safety training and certification of all whose work affects lead-painted surfaces.
Please call 311 to request a free assessment to identify lead hazards in your home or childcare facility and to find out about resources for fixing those hazards.
