Tertiary blast injuries occur as a result of:

Tertiary blast injuries are primarily associated with the impact of the body against other objects as a result of the force generated by an explosion. When a blast occurs, individuals can be propelled into nearby structures, vehicles, or other solid objects due to the sudden displacement of air and the explosive wave. This violent motion can lead to significant trauma, including fractures, internal injuries, and other physical harm resulting from the body's collision with the solid surfaces.

Understanding the mechanisms of blast injuries is crucial in trauma management. While burns and injuries from flying debris and the effects of blast waves on air-filled cavities are significant, they fall into different categories of injuries—thermal and secondary injuries, respectively. Tertiary injuries are specifically related to the direct physical impact resulting from the blast's force, highlighting the importance of recognizing how individuals can sustain trauma through being thrown or impacted by other items in the environment during an explosion.
