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.
One beside the bed, one in the kitchen, and one near the front door.
For oven fires turn off the oven and shut the door. An oven is a fire box, it will contain the blaze. The oven probably isn’t completely airtight but it should be close enough that the fire will use up the oxygen and extinguish itself quickly (the vent will pull hot air out but not let cooler air back in). Let it sit for a while and cool after you can’t see flames anymore to make sure the fire doesn’t reignite when you open the door and let fresh air in. Fire can damage the elements and seals so the oven needs serviced before being used again but so long as the fire was only inside the oven it should be repairable.
Make sure your fire extinguisher has the right rating for the place it is stored. For the oven grease fire, and most kitchen fires, a class K extinguisher would have been most appropriate because it is designed to put out cooking oil fires with minimal splashing.
