Fire extinguisher

Fire extinguishers can be found in Deus Ex and Deus Ex: Invisible War. They take up one space in the inventory, and are used like a weapon. By default they have one unit of ammo, and can be used either to put out fires or blind enemies. They are useful if the player is using a flamethrower, as they can collect a dead enemy's posessions without taking damage from their burning body.

It can also be used by the player to put themselves out if they were ignited by a flamethrower, albeit with taking some damage.
