Common Path 8-0

Common path of travel, commonly misunderstood topic. Confused with Deadend Corridor too many times. Most occupancies common at the travel is limited to 75 feet. H occupancy or Hazard occupancies or space travel is 25 feet. Most are allowed to increase if the building is fully sprinkled/fire protected "Building Code"

Nice

Shout out to another architect using a fountaint pen! I am using the ARE to consume my bloated ink collection LOL.

75 feet, path of travel is not to the doors, it's to a decision point. If you have one door, it will be 75 feet all the way to where you have a decision point i.e. the exit door for the building/stair. If you have to doors leading out the space and required to have two doors leading out the space those doors must be separated by the distance required either one third or one half depending on if the building is fully sprinkled.

Thank you

[@Grateful_Buck]

Let regurgitate what I think you are saying... Egress Travel Distance is 150 ft. At 75 ft there must be choice for the occupant between two possible routes. At which point there is 75 ft left to actually exit door for the building/stair.

If you want to send me a drawing and I can comment on I'm more than happy too. Traveling for work today so all my responses are via my phone.

[@zulfiqarali1376]

thanks for good explanation. can you please tell me that which NFPA deals with pathway or floor marking inside the warehouses? if possible, so please share me the soft copy.

[@johnhansen7822]

If you have a space within a building that only requires one exit and the travel distance (150 feet) to the exit is greater than the common path (CP) distance (CBC Table 1006.2.1 - 100 feet), but less than the exit access (EA) distance (CBC Table 1017.2 - 200 feet), which distance, CP or EA, do you use for Code compliance? My understanding it would be the EA, but now I am not so sure after reading other commentaries. TIA ... John

[@MartyHuie]

It depends, are you following just IBC or NFPA as well. The distance is the distance there is a table for buildings with one exit. I would say you're out of compliance for my gut reaction unless I do a full code search each occupancy type, which you do not state above has a different travel distance to an exit. That also would need to be looked at. I think 150 feet is too far.

[@johnhansen7822]

@@MartyHuie thanks for your reply. I am using the CBC and the use is an S-1 occupancy. I thought I'd be able to use the Table 1017.2 for the allowable travel distance. In lieu of a second exit I am considering an AMMR, but I am not too excited about going through that exercise. I might have another option, but it ain't pretty, ugh.

Please review the last video, number 30 if you have additional questions after viewing that video please let me know

[@luisprunedaarq.7052]

ok so if a room requires 2 doors within that room any distance to those doors can not be more than 75 ft even tough those doors lead to another corridor but not necessarily to an exit please advise

[@MartyHuie]

Luis Pruneda Reading the code, reading the commentary both IBC and NFPA and neither really speak to it well. 2 of the doors must be remotely located from each other as defined in the code. The additional door required could be placed in between or somewhere else within the space. Reviewing this information with some other code officials I know, no one would be comfortable with the 3rd door located side-by-side any of the other doors that are required to be remotely located from each other. So some sort of distance would be required just not side-by-side.

What is the space required around the office furniture for the path. Is this part of OSHA's exit access which must be 28" wide

[@MartyHuie]

May be OSHA, but the building code has very specific requirements and it’s hard to answer that question with a black-and-white answer. If there’s more than one path then likely 28 would be acceptable if there’s not more than one path then 36 minimum. And if the occupant load is over 49 persons then 44 inches would be the minimum, and with any of those you still have to apply ADA turnings face as required as well.

[@stevesafety6743]

@@MartyHuie specifically I have some cubicles that the exit is 20.5 inches wide out of the cubicle because of a building support column. I was using the OSHA exit access of 28”. I had an RA argue that cubicles are furniture and so the building code does not apply

[@MartyHuie]

@@stevesafety6743 OSHA is typically for physical work environments and outside the building, building code absolutely would also apply to the situation I’ve had to remove cubicles before because of this, depending on your building official and how much work they do in this field this could be overlooked and you not have a problem with it, then again you could. Additionally nothing prevents someone from suing anyone and an ADA a person and if there is also an exiting problem when a fire event happens this could be detrimental to the owner and then ultimately to the architect/planner. Just because a person i.e. building official signs off on it they have no liability all liability is on the owner and architect

Can i know that you using the pen? red and blue?
