Aisle widths and fire exits
Aisle widths and fire exits
(OP)
I am currently evaluating our facility for OSHA compliance regarding aisle widths and fire exits. The questions of concern I have are:
Do aisle have to be marked? Do they have to be a minimum of four feet? Do they have to be marked or designated? The OSHA website states that they should be 3 feet wider than the larger material or equipment passing thru or a minimum of four feet. However, I recall in my Facilities Design class that non-main aisles for personnel should be three feet.
Also, with regard to fire exits, do they also have to be marked? I understand that they are to be within a line of sight, marked, and free of obstructions.
Any comments would be greatly appreciated.

RE: Aisle widths and fire exits
Exit routes, or exit access must be at least 28" wide at all points. There can not be anything placed in the isle that will restrict the access to the exit.
All fire exits must be marked according to NFPA 101. They do not have to be within line of site, but you have to provide signage that provides clear understanding of the direction of the fire exit. (this can take several signs, for an example go to a school or large office building with lots of halls) The exits must be locked from the inside, and must be clear of obstructions.
