Abstract:

Under the guidance of the manufacturing Technology Division, Special Technology Branch of ARRADCOM, an extensive series of tests has been conducted to determine the hazard classification of selected plant operations in the new propellant loading facilities. These test evaluations have concentrated on the establishment of critical height and safe separation conditions for these operations such that they can be classified as a Class 1.3 operation as opposed to the more hazardous Class 1.1 explosive operation. The tests concentrated on two primary areas. The first concerned the receiving lines for M-10 propellant and the eventual loading of M-10 into the 81 mm mortar increments. The second concerned the receiving lines for M-1 propellant which were sequentially loaded into bags which already contained either the black powder igniter, the clean burning igniter or the center core igniter. The results clearly indicated that safe separation distances for these operations could be established and that the operations could be classified as 1.3 in accordance with the AMCR 385-100 as amended. It was also determined that should a fire occur in an M-10 loading hopper, this fire could be prevented from transcending into a high order detonation by limiting the height of the propellant in the hopper to not more than 31.8 cm.
