Section 3103.8 of IBC 2006 for Special Construction says unobstructed width not less than 36”.
24”, 30” and 36” seem to be the industry standard.
If this is a mine, I would check the CFR, company standards, or other texts for related information. In my opinion, I like 36” and I don’t like going less. It’s been a while since I did a design, so I would have to go digging in books that I don’t have with me right now.

Subject: 30" wide catwalk
List:
Can anyone confirm that the minimum width of catwalk used in heavy industrial (i.e. for Bulk/Material handling conveyor system) has been changed from 24” to 30” wide? One of our independent checkers made comments regarding this change.
I checked with IBC 2000, 2003 and 2006 nothing mentioned about the change.
Thanks,
Julius
