Schedule 3 chemicals mixed plants

Mixed plants are plants which are individually covered under more than one Part of the Verification Annex related to Article VI. The term covers, for example, a multipurpose plant that manufactures, in the same process line but at different points in time or parallel in several process lines. Schedule 2 and Schedule 3 chemicals (and/or DOCs). However, the term does not relate either to a case where a plant produces a Schedule 3 chemical in a multiple-step reaction involving the production of a DOC in the initial steps, or to a case when, during the production of a Schedule 3 chemical, a low concentration of a Schedule 2 chemical is simultaneously produced (this would be classified as either a Schedule 3 or a Schedule 2 plant depending on the applicable rules for low concentrations). 

Among the hazardous chemical weapons scheduled class 1-3, methyl isocyanate becoming more and more important as a precursor [83]. This is just one among a number of substances which could be made via micro-reactor synthesis. Especially in the case of so-called binary weapons, where two relatively harmless substances are mixed to give a weapon, on-site mixing is demanded this can be accomplished with high performance by micro reactors. Pocket-sized miniature plants can neither be monitored nor detected.
