BLAST MITIGATION ACTION GROUP

The Blast Mitigation Action Group (BMAG) developed a methodology for Damage Level Classification when stray fragments strike the witness panel. This criteria permits minor penetration of stray shards in Zone 4 or 5 provided they are low hazard fragments with minimal penetration. Specifically, if fragments penetrate the witness panel less than 3 mm they are disregarded. If the cumulative depth of all stray fragments striking the witness panel is less than 50 mm and the largest fragment is less than 2 in2, the hazard level designation may be dropped one level... Developed a hazard level classification for total glass fragment mass in Zone 3A and 3B. A Low mass level was defined as a total mass less than or equal to 100 g. Medium mass level is a total mass greater than 100 g but less than 501 g. The High mass level is defined as a fragment mass greater than 500 g. These hazard levels, which are not included in the GSA/ISC criteria, are used to differentiate between the severity of..
