A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
If you have a fever with your cough that doesn’t get better with medication or comes back within a few hours of taking fever-reducing medication, you have shortness of breath, chest pain, body ...
An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when ...
Human beings have about a 50:50 chance of surviving 500 psi, but will probably be severely injured at 70-100 psi. Exposed eardrums will be ruptured 50% of the time at 15 psi. However, a standing man will be blown away at about 10 f/s velocity by a shock of 25 psi peak pressure.
A backdraft (North American English), backdraught (British English) [1] or smoke explosion is the abrupt burning of superheated gases in a fire caused when oxygen rapidly enters a hot, oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Backdrafts are typically seen as a blast of smoke and ...
Commonly referred to as being "blown up", "blown apart", or "dashed to pieces" in older literature, [3] total body disruption may be caused by such traumas as being within or in close proximity to a powerful explosion, uncontrolled decompression, or implosion. It is the most severe type of blast injury. [4]
A law in California that defines "destructive device" includes a list of "weapons" including "[any] sealed device containing dry ice (CO 2) or other chemically reactive substances assembled for the purpose of causing an explosion by a chemical reaction". [11] [12] In Nebraska [13] and other States the noise generated may violate local laws.
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
