IBC/OSHA requirements for rooftop walkway systems
IBC/OSHA requirements for rooftop walkway systems
(OP)
I'm doing some code compliance research regarding roof-mounted walkway systems/catwalks/etc., and although I can find multiple manufacturers on the web, I am more interested in specific IBC and/or OSHA codes that are relevant in the design of such systems. I'm not sure if I will have to extrapolate from information regarding catwalks/handrails/etc. or if there is more specific information that I am missing. I would appreciate if anyone can think of specific codes that would be applicable. I'm also interested in the same information regarding roof-mounted duct supports and cable trays. These systems are not to be involved with general public use and will be in an industrial/private property setting.






RE: IBC/OSHA requirements for rooftop walkway systems
My opinion is that most rooftop walkways and equipment access should be OSHA-compliant and not IBC-compliant. Access up TO the roof is often covered by the IBC - you may need a proper IBC egress stair, but narrow walkways and ladders should be OK on the roof. You should not need a 36"-wide accessible path and 7/11 stairs with closed risers to maintain HVAC units on the roof!
OSHA will offer guidelines for design, but you won't find much to hang your hat on regarding where OSHA applies and where the IBC applies.

Ladders, ships ladders or alternating tread devices can also be used.
