What is the allowed quantity of lead in dry surface paint by weight?

• A. 0.1%
• B. 0.2%
• C. 0.5%
• D. 1%

Answer: (C)

Lead content in paint is defined by weight in the dry film. The regulatory threshold for what counts as lead-based paint is 0.5% lead by weight (5,000 parts per million). Paint with 0.5% lead or more is considered lead-based and must follow lead-based paint regulations and appropriate abatement practices. Paint with less than 0.5% lead is not classified as lead-based under those rules. So, the boundary quantity is 0.5% by weight.
