The mark consists of Beginning on the left side of the mark, a white, eight-point star is completely enclosed within a black four-sided diamond. The points of the star extend to, or nearly to, the four sides of the diamond, or its points. A small black flame is in the very center of the star. The flame itself has five "fire points". A thick black line begins at the left point of the diamond and runs up the upper left side of the diamond, in diagonal fashion. The line, which is continuous, runs up to the top point of the diamond and down the upper right side of the diamond, in diagonal fashion. The line, still unbroken, runs down to the right point of the diamond and bends slightly to the left, such that the line continues away from the diamond, in horizontal fashion. Above this black horizontal line are written the words "U.S. EXPLOSIVE", which are in heavy, bold black capital letters. The horizontal line ends parallel to, and just beneath, the right-hand most side of the second "E" in "EXPLOSIVE". Just below the horizontal black line, beginning immediately below the "U" in "U.S.", is the word "storage", which is in smaller, bold, black lower case letters. The last letter of the word "storage", "e" is immediately beneath the first "E" in "EXPLOSIVE".
