						storing oxygen and refilling portable containers, trailers, mobile supply
						trucks or tank cars.
(2) Bulk
						oxygen storage systems having capacities less than 20,000 cubic feet.

(d) Where it is necessary to locate a bulk
						oxygen system on ground lower than adjacent flammable or combustible liquid
						storage, suitable means shall be taken (such as by diking, diversion curbs, or
						grading) with respect to the adjacent flammable or combustible liquid storage
						to prevent accumulation of liquids under the bulk oxygen system. (Title 24,
						T8-5501(a), (b))
