Footnote(1) New storage containers
									 of the 80 type have not been authorized since Dec. 31, 1947.
Footnote(2) Container type may be
									 increased by increments of 25. The minimum design pressure of containers shall
									 per 100 percent of the container type designation when constructed under 1949
									 or earlier editions of the ASME Code (Par. U-68 and U-69). The minimum design
									 pressure of containers shall be 125 percent of the container type designation
									 when constructed under: (1) the 1949 ASME Code (Par. U-200 and U-201), (2)
									 1950, 1952, 1956, 1959, 1962, 1965, and 1968 (Division 1) editions of the ASME
									 Code, and (3) all editions of the API-ASME Code.
Footnote(3) Construction of
									 containers under the API-ASME Code is not authorized after July 1, 1961.
(3) Containers with foundations attached,
						portable or semiportable b containers with suitable steel "runners" or "skids"
						and popularly known in the industry as "skid tanks," shall be designed,
						installed, and used in accordance with these rules subject to the following
						provisions:
(a) If they are to be used at a
						given general location for a temporary period not to exceed 6 months they need
						not have fire-resisting foundations or saddles but shall have adequate ferrous
						metal supports.
(b) They shall not
						be located with the outside bottom of the container shell more than 5 feet,
						1.52 m, above the surface of the ground unless fire-resisting supports are
						provided.
(c) The bottom of the
						skids shall not be less than 2 inches, 5.08 cm, or more than 12 inches, 30.48
						cm, below the outside bottom of the container shell.
(d) Flanges, nozzles, valves, fittings, and
						the like, having communication with the interior of the container, shall be
						protected against physical damage.
(e) When not permanently located on
						fire-resisting foundations, piping connections shall be sufficiently flexible
						to minimize the possibility of breakage or leakage of connections if the
						container settles, moves, or is otherwise displaced.
(f) Skids, or lugs for attachment of skids,
						shall be secured to the container in accordance with the code or rules under
						which the container is designed and built, with a minimum factor of safety of
						4, to withstand loading in any direction equal to 4 times the weight of the
						container and attachments when filled to the maximum permissible loaded
						weight.
