Lead levels in paint below the federal standard for lead-based paint may still present a hazard under which condition?

• A. When the paint is sealed
• B. When the paint is disturbed
• C. When the paint is cleaned
• D. When the paint is painted over

Answer: (B)

Disturbance is the trigger for a lead paint hazard. Even if the paint’s lead level is below the federal standard, the danger appears when the paint is disturbed because disturbance creates lead-containing dust or chips that can be inhaled or swallowed. Activities like sanding, scraping, drilling, or drywall cutting can release this dust, which is especially risky for children. When the surface is simply sealed, painted over, or cleaned using proper, wet methods and containment, the immediate exposure risk is much lower, assuming the protective layer or cleanup remains intact and effective. So the key idea is that making the paint friable or generating dust through disturbance turns a non-hazardous surface into a hazard.
