Can you go over again how the hybrid isolates its energy system upon impact? Is it dependant on the vehicles 12v system for activation and will cutting the 12v power cause the system to re-energize?
Can Hurst cutters cut through boron steel? Are any rescue manufacturers developing tools for cutting boron steel?
If a hybrid is in an accident where the battery is touching metal, does it not still carry a charge that could potentially threaten electrical shock through the contact? Even when the cables have been severed?
Are you aware of manufacturers’ plans to design quicker shut-offs for these modules?
Can the air bag still deploy if power to the module is cut?
On an undamaged hybrid, are there any precautions/dangers to consider when searching the vehicle for drugs during an interdiction stop?
When I remove the positive cable from a crashed vehicle's battery, I then contact the (+)cable to the ground (-) side in an attempt to discharge capacitors connected to the wiring inside the air bag deployment module. Does the triggering circuitry provide diode isolation to prevent this from working? Basic electricity concept is that if I short out the capacitor, It won't hold a charge thereby (hopefully) preventing it from deploying the air bags.
When inside a crashed vehicle with full PPE, (gloves) it will be difficult to get a purchase point on the interior plastics covering a roof bag pressurized cylinder. Is there any recommended tool for performing the task safely? A large screwdriver may do the trick, but I'd like your input. Perhaps a "wonderbar" carpentry tool would provide better leverage.
Some hybrid vehicles have key fobs and push button ignition switches. How do we disable when there is no key?
The air bag control module decides to deploy the driver's air bag based on parameters during the collision deceleration. Why would there be a deployment after the collision if no electrical impulse was sent during the collision sequence?
Is there a book or reference manual that gives locations of air bags — that first responders can use for reference? Possibly a Web site?
Why aren't vehicle manufacturers required to indicate where all gas cylinders are located in some consistent manner?
Aside from cutting into a cylinder, what is the best way to be certain you have disarmed the air bag system?
Regarding smart systems and pretension devices, are smart systems tied into pre-tensioning devices?
Where are hybrid power cables located?
