Doesn't need to be an extended time. We had an electrical fire in a light next to one of our planes a couple months ago. The maroon that grabbed the fire extinguisher (ABC type) also shot it into the A/P. We ended up having to replace an entire skin panel due to the corrosion (cost the company about 500K in parts and labor).

I've seen stuff on this new type K general purpose extinguisher. Dont know much about it yet.....
