Given a medical gas interior rated storage room, with an amount of compressed gas (O2) exceeding the IFC t105.6.8 permitted amount (504cf), but not exceeding the limit per control area per IBC 307.1(1). Unsprinklered building, single story, VB building, 2018 I-codes.
1) IBC 427.2.2 requires a gas room to be provided with an automatic sprinkler system. In an unsprinklered building I assume a limited area sprinkler system could be provided per 903.3.8 or an alternative system per 904. Are those correct assumptions?
2) Must the fire barriers extend to the underside of the roof sheathing above? I see no exception that would permit termination at a horizontal assembly installed below the roof. (I assume it is designed this way to allow duct to pass over the room, instead of routing around it or using fire dampers).
