CFR · 2024-01-01 · US · Title 14

(a) (1) Hydrogen peroxide in concentrations of greater than 91 percent; (2) Hydrazine; (3) Liquid hydrogen; or (4) Any energetic liquid that is: (i) Incompatible with any of the energetic liquids of paragraph (a)(1) through (3) of this section; and (ii) Stored within an intraline distance of any of them. (b) (1) The quantity of energetic liquid in a tank, drum, cylinder, or other container is the net weight in pounds of the energetic liquid in the container. The determination of quantity must include any energetic liquid in associated piping to any point where positive means exist for: (i) Interrupting the flow through the pipe, or (ii) Interrupting a reaction in the pipe in the event of a mishap. (2) A launch site operator must convert the quantity of each energetic liquid from gallons to pounds using the conversion factors provided in table E-6 of appendix E of this part and the following equation: (3) Where two or more containers of compatible energetic liquids are stored in the same explosive hazard facility, the total quantity of energetic liquids is the total quantity of energetic liquids in all containers, unless: (i) The containers are each separated from each other by the distance required by paragraph (c) of this section; or (ii) The containers are subdivided by intervening barriers that prevent mixing, such as diking. (4) Where two or more containers of incompatible energetic liquids are stored within an intraline distance of each other, paragraph (d) of this secti
