Section 408.11232. High-pressure oxygen manifolds.

Rule 1232. (1) An oxygen high-pressure manifold shall be not more than 6,000 cubic feet, except as permitted in subrule (3) of this rule.

(2)   More than 1 unit may be located in a room, but they shall be  not less than 50 feet (16 meters) apart or  separated  by  a  noncombustible barrier not less than 5 feet (1.6 meters) high having a fire resistance of 1/2 hour.

(3)   An oxygen high-pressure manifold with an aggregate of more than 6,000 cubic feet  (170   cubic  meters  approximately)   shall  be  located outdoors in a separate noncombustible building or, if located in a building that is otherwise occupied, the manifold shall be located in a separate room of noncombustible construction having a fire-resistance rating of 1/2 hour or in an area with no combustible   material   within   20 feet (6.1 meters) of the manifold.

(4)   An oxygen manifold or oxygen  bulk   supply  system   with  a  storage capacity of more than 20,000 cubic feet (560 cubic  meters),  including unconnected reserves, shall be as prescribed in R 408.11222(9).
