Although the release of toxic HN3 is minimal during this mixing, the mixing should be done in the open air, in a well-ventilated area. The solution can then be sealed (and drunk at a later stage to end life).
• An anti-emetic (eg. 3 x 10mg of metoclopramide), taken 40 minutes earlier is advised.
• An analgesic (eg. 500mg - 1gm paracetamol) can be taken at the same time.
• A pre-medicating benzodiazepine (eg. 100mg of diclazepam) can be taken with the azide to shorten the time to LOC.
Note: There is no known antidote to the ingestion of sodium azide. This is considered by many to be a desirable characteristic.
Note: Attempting resuscitation on a person who has ingested sodium azide can expose those helping to serious danger. Mouth- to-mouth resuscitation can result in the rescuer’s exposure to hydrazoic acid. If vomiting has occurred, the toxic vomit must be avoided for the same reason.
The toxic properties of sodium azide, its instability, storage difficulties, and use in the manufacture of explosives mean that the substance is subject to increasing control. Recent publicity over its use as an end life agent has further restricted availability.
