Airbag trigger's disabled

[andres044]

What about the risks of putting the negative in the positive and the positive in the negative pole to damage the electric system including the Airbag trigger system? Is this procedure a SOP in Veh Extrication?

There is most likely a reverse polarity diode protecting that circuit.

I take it you're talking about reversing the cables on the battery terminals and if so, NO!

By doing that you could possibly do two things; 1) Cause a spark that could explode the battery and spray acid all over the place and 2) you might cause a jump in the electrical system and accidently cause the bags to deploy.

The best thing to do is if you can find and reach the battery just disconnect it, negative first. Give a minute or two to let the capicator drain and procede with your extrication. If you can't find the battery in the engine compartment, look under the rear seat or over the rear wheel well. They are the most prominent places these days.

Try to keep anything off of any of the bag covers and keep the patient and emergency worker away from the deployment path if possible.

Be safe.
