What are the main effect of explosion?
Direct, Primary Effects The main direct, primary effect to humans from an explosion is the sudden increase in pressure that occurs as a blast wave passes. It can cause injury to pressure- sensitive human organs, such as ears and lungs.
What kind of injuries are unique to high explosive detonations?
High explosive blasts can cause skull fractures, fractured bones, head injuries, or any traumatic injury (open or closed injuries, chest, abdominal, pelvic injuries, amputations, spinal injuries, and any others). Structural collapse and entrapment can cause crush injuries and compartment syndrome.
Which of the following is the most common cause of death from a blast injury?
The most common cause of death in a blast event is secondary blast injuries. These injuries are caused by flying debris generated by the explosion. Terrorists often add screws, nails, and other sharp objects to bombs to increase injuries.
What causes explosion?
An explosion is caused by a rapid expansion of gas from a chemical reaction or an incendiary device. Signs of an explosion may be a very loud sound or a series of noises and vibrations, fire, heat, smoke, falling glass or debris.
What are the 3 categories of high explosives?
High explosives are divided into three main categories, Primary (or Initiating) High Explosives, Secondary High Explosives, Boosters and Secondary High Explosives, Main Charge.
What causes the greatest damage in an explosion?
The greatest damage of an explosion is the “Mach stem”. That is the region of traveling shockwave where original traveling shockwave constructively interfered with the shockwave reflected. This reflection occurs mostly from the ground in battle conditions.
Which is the most common post explosion injury?
A Primer for Clinicians Key Concepts • Bombs and explosions can cause unique patterns of injury seldom seen outside combat. • The predominant post explosion injuries among survivors involve standard penetrating and blunt trauma. Blast lung is the most common fatal injury among initial survivors.
How are entities affected by an explosion in Minecraft?
Entities are damaged and propelled by an explosion if any are within its damage radius of 2 × power. Note that the “damage radius” is different from the blast radius of explosion effect on blocks. All entities within the radius, define impact = (1 – distance from the explosion / radius) × exposure .
What are the ingredients of a chemical explosion?
Chemical Explosions. Gunpowder is a mixture of potassium nitrate, carbon, and sulfur. Mixtures of these chemicals (in the correct ratios) can produce a chemical explosion. The potassium nitrate is reduced. The carbon and sulfur are oxidized.
