What is the length of the removal area?

• A. 50 feet
• B. 100 feet
• C. 150 feet
• D. 200 feet

Answer: (B)

The main idea here is how large the removal area must be to keep asbestos fibers from spreading while work is underway. The removal area needs enough space to set up barriers, the decontamination sequence (anteroom, clean room, shower), waste staging, and the negative-pressure equipment, without forcing workers to cross contamination boundaries. About 100 feet provides a practical balance: it gives sufficient room to stage and move materials, accommodate decon and waste handling, and maintain a controlled boundary, while still being manageable to install and monitor. A smaller length, like fifty feet, would risk crowding the containment and complicate decontamination; larger lengths, such as 150 or 200 feet, tend to be unnecessarily expansive and harder to control. So the standard target length for the removal area is 100 feet.
