Tertiary blast injury typically results from which of the following?

Tertiary blast injuries are specifically related to the effects of high-energy explosions, where individuals are subjected to the force of the blast. In such scenarios, victims can be violently displaced by the blast wave, which may result in injuries due to being thrown against objects or the ground. This type of injury is distinct from primary and secondary blast injuries, which involve direct effects of the explosion and projectiles, respectively.

Displacement is a key factor in understanding tertiary blast injuries, as the significant energy released during an explosion creates a wave that can forcefully move individuals, leading to potential trauma from impact. This contrasts with other options, which do not directly relate to the mechanism of injury associated with explosions. For example, exposure to toxic substances is related to chemical exposure rather than blast effects, panic disorder pertains to psychological responses, and pressure wave injuries relate specifically to the primary blast effects, not the subsequent displacement of individuals.

Thus, the correct choice highlights the mechanism of injury specific to tertiary blast injuries, elucidating the context of the blast environment and how physical displacement leads to traumatic outcomes.
