As per section 22.15.2.2.1.4 of NFPA 13, 2013 edition, sprinkler protection is to be provided in waste chutes on alternate floors with one sprinkler head at the top and one at the bottom. If a building has a consecutive amount of floors with no access to the chute (for arguments sake, we'll say 5 floors), can sprinkler protection be omitted along… (Show more)
