Preference for disabling hybrid vehicle

[flyingtiger40]

I am taking an informal poll on your preference for method to disable high voltage on hybrid vehicles after a crash.

Before attempting to rescue occupants of a crashed hybrid vehicle, it is important to make sure that the high voltage has been isolated to the battery pack. This prevents the possibility of high voltage electrical shock.

If you check the first responder guides provided by various automotive manufacturers, you see different methods for disabling high voltage.

The following 3 examples are excerpts from first responder guides found on http://www.extrication.com/ERG.htm, in the sections which assume that the ignition key is not accessible...

Toyota 2004 Prius' method is to remove the HEV fuse in the engine compartment junction block.

Ford 2010 Escape's method is to disconnect the negative cable from the 12V battery and remove the service disconnect if possible.

Cadillac Escalade's method is to cut all three exposed 12v positive cables identified
by labels that indicate where to cut.

Of these three methods, which is your preference and why?

I don,t feel any of the methods you listed are adequate. the seven step method listed in previous theads is what I use: Id Hybird vehicle, Stabilise vehicle, Access passenger compartment, Place in park, Turn off igintion, disconect 12 volt battery, & confirm 12 volt shut down.

Please allow me to clarfiy my original question.

Currently there are different methods for disabling the hybrid vehicle high voltage -- different between manufacturers and sometimes even between models of the same manufacturer.

So in terms of future design, I think it would be very helpful if the manufacturer could design one standard way for first responders to disable high voltage. (I know this is unlikely, but please indulge my fantasy).

So if the manufacturers were to ask you to pick from the existing list of methods, what would you like to see as the standard method? If you have a better idea than what's currently offered, feel free to voice that as well.

What about the inertia switches?? it should be de-energized by the time you get there
