Well....it depends on how they were stored.

I thought about that caveat after I posted but really, if you store chemical weapons wrong ....you die. So My assumption would be that they would have been stored correctly.

Yes and no; chemical weapons will degrade and become ineffective over time. There are ways to slow that, so it's possible to store them improperly for shelf life, yet still be stored safely from a handling perspective.
