[1] Synonymous terminology from the field of emergency medical services (EMS) is gross dismemberment.
[4] Gross dismemberment may also be caused by a fall at terminal velocity onto a solid surface or water; from being within a high-speed crashing object, such as in high-speed aircraft crashes; or during incidents involving high pressure differentials, where the body may be forced through a small crevice, as in the Byford Dolphin diving bell accident, or compressed rapidly, as in the Titan submersible implosion.
Total body disruption is invariably fatal to most complex life, such as humans, as structures necessary for continued survival are destroyed or otherwise rendered non-functional.
[5] In some jurisdictions, gross dismemberment is an assessment where EMS personnel may declare death on scene.
[6][7] Incomplete, initially unidentifiable human remains caused by total body disruption may be referred to as "disassociated portions".
