A chemical weapon (CW) is a device that uses chemicals formulated to inflict death or harm to human beings. They are classified as weapons of mass destruction, and have been "condemned by the civilized world". CW has been used in past conflicts; and preparedness doctrine anticipates their potential for future use.
The most dangerous of these are nerve agents GA, GB, and VX, and vesicant (blister) agents H, HT, and HD. All are in liquid form at normal room temperature
