When doing exterior work, doors and windows must be kept closed when closer than how many feet from the renovation work?

• A. 6 feet
• B. 20 feet
• C. 10 feet
• D. 30 feet

Answer: (B)

Minimizing the spread of lead dust during exterior renovations relies on containment. Doors and windows should be kept closed when you are within twenty feet of the renovation work to prevent dust from drifting into the building. This distance helps protect occupants by reducing wind-carried dust entering indoor spaces, which is a key part of lead-safe work practices. The other distances aren’t the standard containment requirement, so they don’t provide the same level of protection.
