Oh god. Sorry to hear this. Is your hand badly burnt? At least theres no garage time involved for your car. I actually remember you pointing out to me in the car park when we were looking under the bonnet of your car that your heater hose had come loose. Anyway yeah, definitely get a fire extinguisher, and try to get a foam one instead of a powder one. The powder cakes up in the bottom of the extinguishers rendering them fairly useless, as I found out when I had my fire!
