This is going to be more of a life pro tip, but trying to reach the largest audience here.
Just had a frantic neighbour knocking at my door saying there is a fire in her oven.
I was over there in under 60 seconds with the fire extinguisher. There was a pot of oil on fire wedged between the element and the rack. No way to quickly and safely remove it, so I blasted it.
If I had tried to remove the pan, it’s likely it would have ended up spilling burning oil everywhere and making the situation much worse. Now they just have a house full of dust to clean.
Will replace our extinguisher today and am considering buying a few more to gift this Christmas.
Not flour, though! A friend once had food in a pot on the stove catch fire, and she knew about putting salt or baking soda on oily fires, but in haste, grabbed the flour, instead. On the bright side, the resulting explosion did put the fire out by consuming the oxygen, but it cracked the kitchen window.
