1103.2 Occupancy classification.
MC § 1103.2
Locations of refrigerating systems are described by occupancy classifications that consider the ability of people to respond to potential exposure to refrigerants. Where equipment or appliances, other than piping, are located outside a building and within 20 feet (6096 mm) of any building opening, such equipment or appliances shall be governed by the occupancy classification of the building. Occupancy classifications of buildings shall be in accordance with the building classifications in the New York City Building Code.
1.Institutional occupancy shall include Occupancy Groups I-1, I-2, I-3 and I-4.
2.Public assembly occupancy shall include Occupancy Groups A-1, A-2, A-3, A-4, A-5 and E.
3.Residential occupancy shall include Occupancy Groups R-1, R-2 and R-3.
4.Commercial occupancy shall include Occupancy Groups M and B, except Occupancy Group M with retail stores having an occupant load of more than 100 persons on any floor other than street level.
5.Large mercantile occupancy shall include Occupancy Group M with retail stores having an occupant load of more than 100 persons on any floor other than street level.
6.Industrial occupancy shall include Occupancy Groups F-1, F-2, H-1, H-2, H-3, H-4, H-5, S-1 and S-2.
7.Mixed occupancy occurs where two or more occupancies are located within the same building. Where each occupancy is isolated from the rest of the building by tight walls, floors and ceilings and by self-closing doors, the requirements for each occupancy shall apply to its portion of the building. Where the various occupancies are not so isolated, the occupancy having the most stringent requirements shall be the governing occupancy.
