The #G7 🇬🇧🇺🇸🇨🇦🇫🇷🇯🇵🇮🇹🇩🇪🇪🇺 has set out our shared priorities for tackling the spread of dangerous weapons around the world.

@gregkoblentz @OPCW Taking out “or disabling physical effects” would make it clearer that only chemosensory irritants fall within the definition of riot control agents.

@gregkoblentz @OPCW CWC Article II.7. currently reads as follows. “Riot Control Agent” means: Any chemical not listed in a Schedule, which can produce rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.

@gregkoblentz @OPCW To further affirm the unsuitability of CNS-acting chemicals for use as riot control agents, it will be important to amend the Chemical Weapons Convention’s Article II.7 (which defines riot control agents) by expunging the language “or disabling physical effects”.

Fantastic snapshot from history: Report of the Conference on Disarmament 1987 (Berlin Wall still up) including a negotiation draft of the Chemical Weapons Convention with „provisional“ lists of scheduled chemicals (104, 112, 115). Looks familiar? #OPCW https://t.co/ZOKx8sPogG

Chemicals are better described through structures than through names. To facilitate the communication between chemists and security experts, we have been working on the structural annotation of lists of chemicals of security concern. @RichardCupitt @gregkoblentz @GPWMDofficial
