Explosions

Most explosions are the result of an accident, such as from a domestic gas leak or boiler mishap, or from routine storage or use of dangerous chemicals. No matter how or why they happen, explosions often cause complete destruction or extreme damage to structures in the immediate vicinity.

• Structures at ground zero may be completely destroyed. Structures at ground zero that suffer damage but survive may be very unstable and in danger of imminent collapse.


• Structures near the explosion site suffer a variety of damage, including: racking, damaged windows and contents, and projectile and fire damage.


• Projectiles can cause damage to other structures and set fires at great distances from the initial blast.


• Powerful explosions can generate seismic shock waves. When set off in a body of water, the explosion can create a tsunami capable of causing damage at a great distance from the blast center.

Ammonium Nitrate Explosion: Texas City, TX 1947 This photo shows how large items can become projectiles as a result of explosion. It takes about 6-8 psi of blast force to lift an automobile. Note the apparent disregard of parking restrictions.
