The other night we came across a situation where a car hit a pole and smashed the drivers side at the A pillar, the steering column was destroyed and the car was still running, we could not access the key.

What are your thoughts and ideas on alternate ways to shut down a running vehicle?

Excellent responses on everyones part so far, in our case we were able to eventually access the key and shut it off but that got us thinking about alternative methods, the car looked like a banana, wrapped around an electric pole on drivers side, only occupant in vehicle will make a full recovery however it will be a long road for him.

he was very lucky, seatbelt + alot of luck + as close to text book extrication and ems services on scene = life saved.

i think the best i heard so far is removing the neg. battery cable until it is a hybrid, many of the manufactures have detailed info on their hybrids available on their websites somewhere.
I'd be really angry to find that my engine's internals were destroyed by the caustic cry chemical that an emergency worker shot into the intake. I've seen more than my share of engine compartment destruction caused by extinguishers and weren't promptly rinsed off.

I guess you'd be upset if the rescue crew cut the roof off as well to extricate you????

If we're talking an urgent situation, them I'm utilising the quickest method to achieve the best results- if it happens to be DCP, then so be it...
Plugging the exhaust will stall the engine as well.
disconnect the battery and the alternator. block the air intake, block the exhaust. take fuses out of the fuse box under the hood. if its an electric hybrid most have disconnect in trunk or behind the back seat.
Okay, i talked with my old Captain, in charge of Extrication training, he said to use what most trucks have, a piece of Visquene plastic and Duct Tape, remove the intake cover at the filter, place the plastic over the air inlet, wrap it tight with the tape. Be forewarned though, stabilize your patient, the vehicle is going to buck until it stalls, also have an extinguisher on hand, it may backfire through the manifold.
I agree with Derek. Plugging the exhaust is the safest way. Most of the times you can´t open the hood to disconnect battery easily. Try to access the key after a crash can be very dangerous because of airbags. Definitely I would choose plugging exhaust.
CO2 - won't get caught in the air filter!

I've seen this on TV, but never tried it. Has anyone out there given this a go? Did it work?

Seriously???
What would it matter? If the car was so destroyed you had to find an alternative way to stop it from running.......not an insurance expert......but I would think the vehicle is totaled, dry chem in the engine wouldn't matter.
Of course, a Banana in the tailpipe, saw it on Beverly Hills Cop...
Flattening the pipe with the hydraulic spreader should work
Just disconecting the battery will not always kill the engine.Most chev products will run without a battery in the vehicle it's only used for starting and keeping enough power in the system to run lights and such in high drain times.The alternator is what makes the juice so you have to disconnect that,But remember that most cars and trucks today you have no room under the hood to get to anything so may not be a viable option either.If the vehicle is wedged in a ditch your not going to get under to crimp a fuel line.A coil wire is a good method to but some have coil packs now where it's all bolted in.
I'm going to have to say the quickest but not sure how long it takes is stuff the tailpipe to kill it and then go after a fuse or relay under the hood.This is a great thread and I have a few mechanic buddies and I'm going to pose them this question and I will get back to everyone later.
I agree this is a really great thread and I have learned a lot from reading everyone's post. Thanks guys.... I have just been educated in mechanics.
