    2021 code:

    5.1.3.1.8 Locations containing positive pressure gases other than oxygen and medical air shall have their door(s) labeled as follows: ...


    Proposed 2024 code change to:

    5.1.3.1.8 Locations containing positive pressure gases other than oxygen and medical air shall have their entrance(s) labeled as follows: ...


    Changing the NFPA 99 code would avoid this conflict with the NFPA 80 code.


    Per NFPA 80, 4.1.4, no more than 5% of a fire-door’s surface may be covered by a sign.

    Per NFPA 99, 5.1.3.1.8, locations containing medical gas manifolds, shall have a label on the door.  The label has lots of words and has to be readable from 5' away per 11.3.10.1 so it's likely that it obscure more than 5% of the door's surface.

    *  There are other NFPA 99 codes (e.g. 5.1.3.1.9, chapter 15, etc.) that need the same word change from "door" to "entrance."

    I do not have a problem with this proposal.

    This is a great suggestion.  We have run into the 5% issue several times and changing the wording from "Door" to "Entrance" would definitely seem to solve this problem.
