Generally, items should not be stored in corridors. Certain equipment (lab refrigerators, metal enclosed file cabinets, etc.) may be stored in approved corridors under the following conditions:

1. All items in any particular corridor are placed along one side of the corridor only, with the other side kept clear for emergency evacuation.
2. An 18-inch clearance, from the top of any storage to the ceiling, to prevent interfering with the sprinkler system operation, is maintained.
3. Do not block fire exits or entrance doors.
4. A clearance of three feet around all safety showers is maintained.
5. A minimum corridor width of 44 inches at any point for occupant movement/evacuation is maintained
6. No work with any stored chemical or biological material is allowed.
