I had the pot of oil on an electric stove and it overflowed when I added the food. Since the base of the pot was slightly smaller than the hotplate, some of the oil did spill onto the plate and when I removed the pot to put in the sink, the oil covered the rest of the plate and ignited. The old magazines which were lain around the plate and normally make clean up of oil splatter easier also added to the hazard.
Of course, the correct action plan should have been (a) shut off power immediately, (b) remove all other fuel around area, (c) remove pot from stove, then (d) contain any fires by using a pot lid.
Cleaned the stove and area a few times now with a degreasing soap detergent. Done the best I can and it all seems alright with not much other of the soot stains that can come out (if they were even inflicted from this fire anyway). A couple of spots on the polymer benchtop has melted out (between the hotplate glass and splashback). The stove appears to still be working fine and there has been no cut outs, further fires, electric shocks or reduction in heating performance.
Time to deal with another QLD problem - ants...
