Do you have access to a toilet? Indoor? Outhouse?

5 grams in 500 ml of water. Good Lord if you add a whole bunch of
chemicals to do some dastardly thing to the azide you will have added
more junk to the environment than if you just dump it down what ever
receptacle you sit on after you have completed digesting whatever you
gorged yourself on a few hours ago.

Think! Think! The regulators don't necessarily think. Don't increase
the environmental load unnecessarily.

If you just gotta oxidize it in order to sleep nights add enough
permanganate to a slight pink color and then add enough vodka to turn
it colorless.

I agree.

The jerk has 5 grams in 500 ml of water. When he dumps it in the
toilet bowl and flips the handle the 5 grams is followed by and mixed
with perhaps 5 gallons of water. It enters the sewer system and gets
mixed with mixed with Gawd only knows how many gallons of water plus
various other organic species including a few condoms.

There just ain't any harm gonna come to anybody from HN3  who sticks
their nose down a sewer pipe and sniffs . The product of any reaction
isn't going to cause any harm to the population or the environment.
You are going to get some sodium ions and some products of the
oxidation of the azide ion. Now go back and look at the crap that
other posters suggested you add to render the azide harmless. What in
hell are you going to do with this increasing volume of contaminants?

All you need to do is look at all of the "paper" solutions to this
problem and it is obvious that the "solutions" contribute more to the
problem than the "flush".

Zugor sometimes you just gotta stop and think. Sometimes government
regulations just do not make any sense. Your problem is one of those
