Don't quote me but 134a should be safe to discharge into the air. Those little canned air computer dusters are just cans of pressurized 134a. You just have to get a way of safely releasing it.

Now if it was R12, it would definitely be a good idea to get it to an A/C shop to recover it for recycling. R12 is a finite resource these days.
