me:ahhhhh!!!! 911:sir we are traceing the call now me:omg im on fire ahhhhhh!
I will however say that for me the fire started because we had accidentally left the gas on with the lid covered for about half an hour, and when I unknowingly opened the lid after that continuous heating, the grease burst into flames: so it may have been somewhat stronger than a normal grease fire, but in any case I would advise everyone to familiarize themselves with the available counter measures because grease fires have the potential to cause devastating damage.
