Chemical weapon

Device that uses chemicals to kill or harm individuals

A chemical weapon (CW) is a specialized munition that uses chemicals formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves." Lethal chemical weapons include nerve agents (tabun, sarin, soman, VX/VR, and Novichok) and blister agents (primarily mustard gas).
