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.
Lol, white dust is what a dry powder extinguisher is meant to spit out. Ths issue is that if the powder becomes too compacted, it won’t come out. Look up a video of a dry powder extinguisher in use to see if it’s working like it should.
However, they are more-or-less single use. If you’ve used it, even partially, you should really get it recharged or replaced.
