I have done quite a bit of training on vehicle extrication and so forth involving airbags. Just because the battery is disconnected, the fuse is out, so on and so on does not necissarily mean that the airbag wont deploy. Also, im pretty certain that there is no easy way of setting off the airbags manually because the motion sensors require movement, then a sudden stop (although i have seen them set off after the wires have been cut and they were attatched to a 12v battery). Not sure if this makes sense to any one, or helps at all but i figured id chime in.
