Thank you, Doc. Based on this, the powder is bad, so I’ll dispose of it.

Smell the powder. If it doesn't smell acrid and the container looks good, it's fine. Store it somewhere cool and dry, but not in a sealed metal box such as a safe or ammo can

As Mike said, bad powder will curl your nose hairs. It is like sniffing a gallon bottle of acid.

That said, 'good' powder doesn't smell all that great either, but it is a solvent smell.

If you have any doubt, just chuck it. Powder is still pretty cheap. For disposal, you can spread it on your lawn, as the nitrogen in the powder is a pretty good fertilizer.

That's what I was always taught.
