If you are exposed to nerve agent how many CANA (anti-convulsant) auto injections should you administer to yourself or to a casualty before seeking medical guidance?

If exposed to a nerve agent, you should administer a total of three CANA (convulsant antidote) auto-injections. The first injection should be given immediately, followed by a second injection within 3 to 10 minutes if symptoms persist, and a third injection can be given 10 to 15 minutes after the second if necessary. After administering the injections, seek medical guidance as soon as possible. Always follow specific guidelines and training provided for responding to nerve agent exposure.
