Airbag light

Got a Chevy Prism and there is something going on with the airbag light. it came on for no apparent reason and it wont turn off even when the car is off. I have no clue what is causing this and i cant find the fuse to remove so i can make sure the airbag wont go off unexpectedly. if anybody has any info and/or help PLEASE let me know with a pm or on here. thanks
