What type of paint is classified as lead-based?

The classification of lead-based paint specifically hinges on the concentration of lead within the paint. Paint that contains 0.5% lead or more by weight, which equates to 5000 parts per million (ppm), is considered lead-based. This measurement is significant because it establishes a clear threshold that defines lead-based paint within regulatory guidelines.

Recognizing 0.5% as the pivotal point helps ensure that the risks associated with lead exposure can be addressed effectively, given that higher concentrations of lead in paint present greater health risks, particularly to children and pregnant women.
