Emergency The Effects of
an Explosion
Blast Lung
This is a condition caused by a pressure wave of over 5000 Mega-Pascals entering the lungs, guts and ears resulting in internal bruising, bleeding and possible lung collapse.
 
Amputations
When the pressure wave from the blast enters the body, the sheer force will cause snapping of bones. The winds that follow the pressure wave will rip the flesh and muscle resulting in limbs being torn from the body.
 
Burns
A fireball of 2000°C/3632°F lasting no more than 0.5 seconds will cause severe burns and scolds.
 
Displacement Injuries
Injuries such as broken bones, head injuries and severe bruising will result from the sheer force of the blast, which will throw the body in the air. These injuries will be extensive and often fatal. If the casualty is in a building, furniture and other objects will be thrown against them. Building collapse is likely, crushing and engulfing the victim.
 
Fragmentation Injuries
Moving within the pressure wave, items of debris will accelerate to become high-velocity projectiles in excess of 1,000 metres per second. They will penetrate the skin causing injuries ranging from superficial secondary fragmentation injuries to serious damage resulting in amputation or blindness.
 
Other effects of the pressure wave may be the sucking of eye-balls from their sockets, bursting the ear-drums and severe radiation. Survival will depend on the extent of the injury, the onset of shock, the actions of the victim, arrival of emergency services and the evacuation process.
