What type of blast injury occurs when a casualty is thrown against an object?

The type of blast injury that occurs when a casualty is thrown against an object is classified as a tertiary blast injury. Tertiary injuries result from the displacement of the body caused by the pressure wave generated by an explosion. When an individual is thrown forcibly, they may impact with nearby objects, which can lead to blunt force trauma, fractures, or other physical injuries.

In this context, tertiary blast injuries involve the kinetic energy imparted to the body from the explosion's shockwave, which then leads to further harm upon striking stationary objects. This distinction is crucial in a tactical paramedic context, as understanding the mechanism of injury informs appropriate emergency response and treatment protocols for victims of blast incidents.
