Lead-based paint is a hazard when which conditions are present?

Lead-based paint is a hazard when which conditions are present?

• A. Paint is intact and on non-contact surfaces.
• B. Paint is deteriorated, lead paint is on friction or impact surface, lead paint is on child-accessible surface that shows evidence of teeth marks.
• C. Only presence of lead is enough regardless of condition.
• D. Lead is only hazardous if ingested.

Answer: (B)

Lead hazards occur when lead-based paint is in a condition that can release lead into the environment. The strongest risk is from paint that is deteriorated and located on friction or impact surfaces (like window sashes, doors, and trim) because those areas wear down and shed dust and chips. It’s also hazardous when the paint is on surfaces that children can reach and those surfaces show evidence of teeth marks, since mouthing can transfer lead into the body. In these situations, lead dust or chips can be ingested or inhaled, increasing blood lead levels. Intact paint on non-contact surfaces poses little immediate risk because it’s not easily releasing lead. Simply having lead present isn’t enough to define a hazard; the condition and potential exposure pathways matter. And lead exposure can occur through inhalation or ingestion, not just ingestion. So the scenario describing deteriorated lead paint on friction/impact surfaces and on child-accessible surfaces with teeth marks best represents a lead hazard.
