3.3.1.5 Debris Impact (FEMA -426)
Debris impact may be minimal in response to a low- or moderate-in¬tensity threat; however, façade materials may be locally overwhelmed, in response to a low-intensity short-standoff detonation, or generally overwhelmed, in response to a large-intensity long-standoff detonation. Airborne glass fragments typically cause penetration or laceration-type injuries. Larger fragments may cause non-penetrating, or blunt trauma, injuries. Finally, the air-blast pressures can cause occupants to be bodily thrown against objects or to fall. Lacerations due to high-velocity flying glass fragments have been responsible for a significant portion of the injuries received in explosion incidents. Although these injuries are se¬rious, the building structure remains intact preventing the possibility of more injuries and fatalities.
