Minimum Nonpropagation Distances for M42/M46 GP Grenade Loading Tools
Abstract
As part of an Army-wide expansion and modernization program, the safe separation distance criteria to specifically support modernization concepts for the assembly of M42/M46 GP Grenades into various projectiles were studied. The test results from this program were used to establish safety criteria for new and existing explosives manufacturing facilities. A series of exploratory and confirmatory tests were conducted for each of the three loading tool configurations studied (two ring packs and a cluster tray). The M483 ring pack, containing eight grenades, had a nonpropagation distance of 30 centimeters (12 inches) with a propagation probability of 6.98%. The M509 ring pack, containing 15 grenades, had a nonpropagation distance of 45 centimeters (18 inches) with a propagation probability of 7.11%. The cluster trays, each containing four rings of eight grenades, were found to have only a 6.25% propagation probability within the trays; therefore, zero spacing between trays has been safety approved.
