Expiration dates are for liability purposes. As long as packaging is intact, contents should be fine for things like gauze. You have to look at risk-benefit for the other items. There are ammonia vials in there, and even if they went bad wouldn't be harmful to at least try. Same with disinfectant. Same with pain relievers. It may not be as effective as fresh, but the chances of it hurting you are negligible.

I read about a study where the Army (?) tested some sort of antidote (mustard gas?) that was 30 years past its expiration date and it was found to be still effective.

Reminds me of someone's sig - I'm not a doctor, but I'd be happy to take a look.
