How far must plastic extend from the activity during exterior renovation work?

• A. 6 feet
• B. 10 feet
• C. 20 feet
• D. 15 feet

Answer: (B)

Containment distance is the key idea here: to keep lead dust from traveling beyond the work zone, you set up a plastic barrier around the exterior renovation area. Extending the plastic at least 10 feet from where the work is happening creates a safety buffer that catches dust and debris generated by scraping, sanding, or other activity, preventing it from landing on nearby surfaces, ground, or bystanders. Secure the plastic so it forms a continuous, sealed barrier and keep it in place until cleanup is complete. This distance balances effective containment with practicality, whereas shorter distances could miss dust that becomes airborne or settles next to the work area, and longer distances aren’t required for standard exterior work.
