Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. 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 ...
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.
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 ...
An upper respiratory infection like the common cold, the flu, or COVID-19 ... If you have a fever with your cough that doesn’t get better with medication or comes back within a few hours of ...
The same is true for RSV, a common respiratory virus that's usually more like a cold for adults but can be dangerous for young children, babies and older adults with chronic medical conditions.
The explosion killed 33 and wounded 69 others when the building collapsed. It is considered one of the deadliest disasters to have occurred on the island. On September 11, 1998, in Bucheon, South Korea, an LPG filling station for propane and butane caught fire, causing a massive fire and several very large explosions.
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.
Aspen trees have also been observed to explode in wildfires. [31] Steam pressure build up in tree trunks is theoretically unlikely to lead to an explosion in a rapidly moving fire front, although trees exploding after the initial front has passed or exploding through other mechanisms is entirely possible.
