Q: In a hospital emergency department, can the corridors be 6 feet wide? Can the hospital install an 18-inch deep lockable computer cabinet in the 8 foot ED corridor?
A: Well… It depends.
If you claim the ER is a suite, then there would be no problem with a cabinet in the 8-foot wide hallway…. Because there are no corridors in a suite. What looks like a corridor in a suite is a communicating space and you would only have to maintain 36-inches clearance for aisles.
But if the ER is not a designated as a suite, then you must maintain corridor widths. But the required width of the corridor is different depending on the occupancy classification of the ER. CMS has said that Emergency Departments must be classified as healthcare occupancies (HCO) if the ER has patient observation beds. CMS’s logic on this is if patients are under observation in the ED, then they consider this patient sleeping accommodations. In this logic, then all areas providing patient sleeping accommodations must be healthcare occupancies, and the required width of the corridor must be 8-feet.
However, CMS does permit the Emergency Department to be classified as an ambulatory health care occupancy (AHCO) if the ER does not contain any patient observation beds. Then the corridor width is only required to be 44-inches wide.
But keep in mind, the maximum corridor projection permitted by CMS is 4-inches. If your ER is not designated as a suite, then you must maintain corridor widths (either HCO widths of 8-feet, or AHCO widths of 44-inches) and you cannot have corridor projections more than 4-inches, and the cabinet would not be permitted.
