Were you able to use the same fire extinguisher both times?
I thought that most of them were exhausted after just a couple of seconds.
Yes David I was. The fire first appeared small and under the stove and was put out quickly. A couple of seconds later I heard a popping sound, which must have been the fuel hose melting. That is when I found that the bulk of the fire was behind the stove in a galley storage compartment where the fuel hose is routed. That burst finished the extinguisher and put out the fire. I picked up the second one and was at the ready but no more fire appeared anywhere. After an hour I started cleaning up the powder.
Those small ABC extinguishers do not last too long, but powder was everywhere. I have four near the galley.
