"Definition." As used in this section, "Containers" - All vessels, such as tanks, cylinders, or drums, used for transportation or storing liquefied petroleum gases.
"Containers in use" means connected for use.
Portable heaters, including salamanders, shall be equipped with an approved automatic device to shut off the flow of gas to the main burner, and pilot if used, in the event of flame failure. Such heaters, having inputs above 50,000 B.t.u. per hour, shall be equipped with either a pilot, which must be lighted and proved before the main burner can be turned on, or an electrical ignition system.
NOTE: The provisions of this subparagraph do not apply to portable heaters under 7,500 B.t.u. per hour input when used with containers having a maximum water capacity of 2 1/2 pounds.
Storage outside of buildings, for containers awaiting use, shall be located from the nearest building or group of buildings, in accordance with the following:
TABLE F-3 _______________________________________ Quantity of LP-Gas stored | Distance | (feet) _____________________________|_________ 500 lbs. or less............ | 0 501 to 6,000 lbs............ | 10 6,001 to 10,000 lbs......... | 20 Over 10,000 lbs............. | 25 _____________________________|_________
"Systems utilizing containers other than DOT containers" -
"Application." This paragraph applies specifically to systems utilizing storage containers other than those constructed in accordance with DOT specifications. Paragraph (b) of this section applies to this paragraph unless otherwise noted in paragraph (b) of this section.
"Design pressure and classification of storage containers." Storage containers shall be designed and classified in accordance with Table F-31.

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, 1061.
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:
When LP-Gas and one or more other gases are stored or used in the same area, the containers shall be marked to identify their content. Marking shall be in compliance with American National Standard Z48.1-1954, "Method of Marking Portable Compressed Gas Containers To Identify the Material Contained."
"Damage from vehicles." When damage to LP-Gas systems from vehicular traffic is a possibility, precautions against such damage shall be taken.
