According to ICR 56, how large must the clean room of the decontamination unit be if there are 17 workers on the project?

• A. 64 ft2
• B. 96 ft2
• C. 128 ft2
• D. 160 ft2

Answer: (B)

The key idea here is that the clean room size in a decontamination unit is set by how many workers will be using it, to ensure there is enough room for donning and doffing, orderly movement, and contaminated-to-clean transitions without crowding or bottlenecks. ICR 56 provides a table that links the number of workers to a minimum clean room area. For 17 workers, the appropriate minimum area given by that table is 96 ft^2. This size balances having enough space for the workflow—entry, doffing stations, and passage between zones—without wasting space. A smaller area would be too cramped for 17 people, while larger options would exceed what the regulation requires for this crew size.
