What is the width of the removal area?

• A. 30 feet
• B. 50 feet
• C. 70 feet
• D. 90 feet

Answer: (B)

The width of the removal area is set to ensure proper containment and space for the required controls and workflow. Fifty feet provides enough room to place barriers, a decontamination corridor, and the necessary negative‑air or HEPA filtration equipment, while still allowing safe access for workers and equipment. A narrower width would make setup and decontamination hard to manage and increase the risk of fiber escape, whereas a much wider width adds unnecessary distance and cost without added safety in typical scenarios. So fifty feet is the best balance for safe, efficient containment.
