How wide must the clear aisle be in a storage room?

• A. 2 ft
• B. 3 ft
• C. 4 ft
• D. 6 ft

Answer: (B)

Maintaining a clear, unobstructed passage in a storage area is all about safe access for people and the equipment they use. The minimum width that allows an average person to move through and also lets a hand truck or cart pass by shelves is three feet (about 36 inches). A space of only two feet is too narrow for comfortable, safe movement or for maneuvering equipment, while widths of four or six feet are larger than necessary for most storage layouts and would waste space. So the minimum required clearance is three feet.
