It should make you nervous, it's important to sit at least 10"-12" away from the airbag. I brought an airbag from a used steering column I bought for my daughter's old car into the shop and set it off during lunch one day- for 2 reasons (1) who doesn't like explosions? and (2) if the manual says to depower the airbag before a procedure, I wanted my techs to do it. I sat the bag on the floor with the upholstered side up and it flew 10' in the air from the rebound, if I'd had it upholstery down it probably would have gone through the roof. I hate those things, buckle the seat belt, adjust the seat and headrest properly, stay sober, put your "smart" phone down, and you won't need airbags.
