9.2.2 Definition
The prevention of development, production, stockpiling, and use of chemical weapons was
formed in 1992 by the Organisation for Prohibition of Chemical Weapons. Sarin gas was used in Matsumoto in 1994 and in the Tokyo subway in 1995 [1]. Civilian security is also threatened by malpractices in industry and accidents that lead to release of toxic industrial chemicals. Organisation for Prohibition of chemical weapons has classified chemical weapons into three categories - schedule 1, 2, and 3. Schedule 1 chemicals (nerve agents) have very limited industrial uses. Schedule 2 chemicals (example are Amiton, PFIB, dimethyl methylphosphonate precursor to sarin) have limited legitimate use on small scale. Schedule 3 chemicals (examples are chloropicrin, hydrogen cyanide and phosgene) are those which have large scale uses. The
schedules limit the use of chemicals as identified in the conventions [2].
