This performance specification is approved for use by Departments and Agencies of the Department of Defense (DoD).

1.0 SCOPE

1.1 Scope. This Technical Statement of Need (TSN) document describes the requirements for an Explosive Ordnance Disposal armor system ensemble. This is a personal protective equipment system that provides whole body blast effects protection to Explosive Ordnance Disposal (EOD) personnel. (See Section 6.1) The bomb suit ensemble is used in situations where the EOD Soldier will attempt a Render Safe Procedure (RSP) or Disposal Procedure (DP) against Unexploded Ordnance (UXO) or Improvised Explosive Devices (IED) that cannot be attacked remotely. The Explosive Ordnance Disposal Armor System is a Critical Safety Item (CSI). The Suit, Explosive Ordnance Disposal is a whole body blast effects protective ensemble consisting of the following primary protective components: head protection (helmet and visor), torso and arms protection (jacket), legs and feet protection (trousers). The ensemble includes carrying cases/bags for the suit and the helmet system. This TSN delineates the performance requirements of the ensemble.
