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). It was first used by the British Army's Special Air Service in the late 1970s.
|Type||Non-lethal explosive device|
The flash momentarily activates all photoreceptor cells in the eye, blinding it for approximately five seconds. Afterward, victims perceive an afterimage which impairs their aim. The sheer volume of the detonation also causes temporary deafness in the victim and also disturbs the fluid in the ear, causing a loss of balance. Despite the nonlethal intentions behind the grenade, the resulting concussive blast still has the ability to cause injuries, and the heat created has been known to ignite flammable materials. The fires that occurred during the Iranian Embassy siege in London were caused by stun grenades coming into contact with flammable objects.
Unlike a fragmentation grenade, stun grenades are constructed with a casing made to remain intact during deflagration and avoiding fragmentation injuries, while having large circular cutouts to allow the light and sound of the explosion through. The filler consists of a pyrotechnic metal-oxidant mix of magnesium or aluminium and an oxidizer such as potassium perchlorate or potassium nitrate.
While stun grenades are designed to limit injury to their targets, permanent hearing loss has been reported. Other injuries and deaths have also been caused by their use, usually when a grenade detonated close to a person, or due to structure fires caused by detonation. These include the following:
List of incidentsEdit
- In 1989, police in Minneapolis, Minnesota, conducted a drug raid at the home of an elderly couple, Lloyd Smalley and Lillian Weiss, after receiving inaccurate information from an informant. The stun grenades police used in the raid set the home on fire. Police said they were certain no one was inside, and so, at first, made no attempt at rescue. Smalley and Weiss died of smoke inhalation.
- In May 2003, a woman named Alberta Spruill died from a heart attack after a police team detonated a stun grenade at her residence in Harlem, New York while looking for a drug dealer who was already in police custody. Her family eventually won a $1.6 million civil suit against the city.
