How does a flashbang grenade work?
The grenade is thrown and explodes after a roughly 1.5-second delay. The explosion of magnesium-based pyrotechnic chemicals causes a very bright flash and a loud sound (160−180 decibels), which can cause temporary blindness, temporary loss of hearing and loss of balance, as well as a sense of panic.
What is inside of a flashbang?
The flash powder used in creating the light and sound normally contains potassium perchlorate and aluminum powder. While this mixture produces bright light and a loud sound report, it also produces a significant amount of smoke through the formation of potassium chloride and aluminum oxide.
How powerful is a flashbang?
A stun grenade, also known as a flash grenade, flashbang, thunderflash or sound bomb, is a less-lethal explosive device used to temporarily disorient an enemy’s senses. It is designed to produce a blinding flash of light of around 7 megacandela (Mcd) and an intensely loud “bang” of greater than 170 decibels (dB).
Who invented flashbang?
A stun grenade, also known as a flash grenade or flashbang, is a non-lethal explosive device used to temporarily disorient an enemy’s senses.

Can a flash grenade blind you?
Also known as stun grenade, a flash-bang is a non-lethal explosive device that emits an extremely loud bang and bright lights to disorient people as it goes off. They can cause temporary blindness and shifts in hearing, typically lasting a few seconds, per a paper in the American Journal of Operations Research.
Do Flashbangs do permanent damage?
Flashbang grenades are Non-Lethal Weapons (NLWs). Like all NLWs, they are intended to have reversible effects on personnel and materiel.
Can a flashbang blind you?
“Flashbang grenades will cause an effect called ‘flash blindness’ which is due to overloading the light receptors in the eye and causing a significant afterimage,” CEENTA Ophthalmologist Ernest Bhend, MD, said. “The effect is temporary and reversible.
What happens if a flashbang goes off in your hand?
“If a conventional flash-bang goes off in someone’s hand or lap, they have the potential to do a lot of damage,” Grubelich said. “But because ours do not operate with this pressure explosion, they will not cause severe blast injuries. You may get superficial flash burns but you won’t lose any fingers.”
Can a flashbang cause permanent damage?
There is a risk that flashbang grenades can lead to an injury called Permanent Threshold Shift (PTS), an irreversible hearing loss caused by exposure to intense sound (as opposed to the reversi- ble Temporary Threshold Shift (TTS) that also results from intense sound exposure) (Farlex Partner Medical Dictionary 2012c).
What is the purpose of a flashbang?
A flash-bang is a non-lethal explosive device that is often used by police to stun and disorient people. The devices make a loud noise and emit a bright flash of light when they explode, temporarily blinding and deafening people nearby. They are also known as stun grenades.
How loud is a flashbang?
A flashbang creates a noise louder than 170 decibels when ammonium nitrate is detonated. For comparison, a jet engine is just over 140 decibels. A sudden noise that loud can cause temporary deafness and tinnitus. It also disrupts the inner ear fluid, which can cause a loss of balance.
What happens when a flashbang goes off?
