In a flash fire, the flame spreads at subsonic velocity, so the overpressure damage is usually negligible and the bulk of the damage comes from the thermal radiation and secondary fires. When inhaled, the heated air resulting from a flash fire can cause serious damage to the tissue of the lungs, possibly leading to death by asphyxiation. Flash ...
There is a rapid build-up (or "spike") in temperature due to the compound effect of rapidly burning (i.e., deflagrating) gases and the thermal cycle they produce. This is generally the best indication of a flashover. [2] The fire is in a ventilated compartment, so there is no shortage of oxygen in the room. [citation needed]
A stun grenade, also known as a flash grenade, flashbang, thunderflash, or sound bomb, [1] is a non-lethal explosive device used to temporarily disorient an enemy's senses. Upon detonation, a stun grenade produces a blinding flash of light and an extremely loud "bang".
When flame velocities are low, the effect of a deflagration is to release heat, such as in a flash fire. At flame velocities near the speed of sound , the energy released is in the form of pressure, and the resulting high pressure can damage equipment and buildings.
Muzzle flash of a revolver. Note the minor flash at the gap between cylinder and barrel. Muzzle flash can be broken down into five distinct components. [1] The muzzle glow is a reddish glow that is visible before the bullet leaves the barrel. It glow is created by superheated gases that have leaked past the projectile and have exited the barrel ...
An arc flash is the light and heat produced from an electric arc supplied with sufficient electrical energy to cause substantial damage, harm, fire, or injury. Electrical arcs experience negative incremental resistance , which causes the electrical resistance to decrease as the arc temperature increases.
Flash powder should only be made at the site at which it will be used. Additionally, the mixture should be made immediately before use. When mixed, the transportation, storage, usage, various possession, and illegal "firearms" laws (including felonies) may come into effect that do not apply to the unmixed or pre-assembled components.
