Thanks for all the responses.
Rich, I am glad someone finally said it: and yes, my goose was cooked. Almost really REALLY cooked. I was lucky.
I bought 4 new extinguishers, (3) 1xABC (gave one to the neighbor since she used hers) and (1) 3x for the garage.
I have looked all through the house and still cannot find the big one!
As I was processing this event it occurred to me that I always carry a bandana and it would have only taken a second to pull it out and put in on top of my hand as I reached in to turn off the propane tank valve, protecting my hand form dripping fat. The burns will heal ok but had this been a bug out condition, this type of burn not properly cared for could be a serious problem.
