Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Only approved containers and portable
						tanks shall be used. Metal containers and portable tanks meeting the
						requirements of and containing products authorized by Chapter 1, Title 49, of
						the Code of Federal Regulations (DOT Regulations), or NFPA No. 386, Standard
						for Portable Shipping Tanks, shall be deemed to be acceptable.
(b) Each portable tank shall be provided with
						one or more devices installed in the top with sufficient emergency venting
						capacity to limit internal pressure under fire exposure conditions to 10 psig,
						or 30 percent of the bursting pressure of the tank, whichever is greater. The
						total venting capacity shall be not less than that specified in Subsections
						5593(d) or (f). At
						least one pressure-actuated vent having a minimum capacity of 6,000 cu. ft. of
						free air per hour (14.7 psia and 60° F) shall be used. It shall be set to
						open at not less than 5 psig. If fusible vents are used, they shall be actuated
						by elements that operate at a temperature not exceeding 300 F. When used for
						paints, drying oils, and similar materials where plugging of the
						pressure-actuated vent may occur, fusible vents or vents of the type that
						soften to failure at a maximum of 300 F. under fire exposure, may be used for
						the entire emergency venting requirement.
(c) Containers and portable tanks for
						flammable and combustible liquids shall conform to Table FL-2.
EXCEPTIONS:
(1)
						Medicines, beverages, foodstuffs, cosmetics, and other common consumer items,
						when packaged according to commonly accepted practices, shall be exempt from
						the requirements of 5532(a).
(2)
						Glass or approved plastic containers of no more than 1-gallon capacity may be
						used for a Category 1 or 2 flammable liquid if:
(A) Such liquid either would be rendered
						unfit for its intended use by contact with metal or would excessively corrode a
						metal container so as to create a leakage hazard; and
(B) The user's process either would require
						more than 1 pint of a Category 1 flammable liquid or more than 1 quart of a
						Category 2 flammable liquid of a single assay lot to be used at one time, or
						would require the maintenance of an analytical standard liquid of a quality
						which is not met by the specified standards of liquids available, and the
						quantity of the analytical standard liquid required to be used in any one
						control process exceeds one-sixteenth the capacity of the container allowed
						under Table FL-2 for the category of liquid; or
(3) The containers are intended for direct
						export outside the United States.
