Explosive Tests for Establishing Hazard Classification for M1 SP Propellant in Automated Single-Base Finishing Operations
Abstract
Adequacy of a prototype propellant storage hooper was established for venting burning reaction gases to preclude an explosive reaction in the air- dry operation of the automated single-base line (ASBL). Four hundred and fifty pounds of M1SP propellant (for 105 mm ammunition) did not transit from burning to an explosion when bottom flame initiated in a specially designed hopper incorporating pressure-relief venting. Implementation of this hopper design will reduce an assessed Class 7 explosive hazard to a Class 2 burning hazard in ASBL finishing operations. The ratio of propellant surface to hopper vent area was determined which will permit venting of burning gases and, in turn, preclude an explosive reaction in manufacturing and storage vessels. Also the susceptibility of M1SP propellant to transit from burning to an explosion was established in steel confinement in test diameters up to 18 inches.
