How can I send you a video question for a dishwasher head scratcher I’d love your take on it, I found something in my dishwasher and can’t figure out where it should go, it fits directly into the water line feeding the upper spray arm which when installed obviously acts as a plug, so I want to show you and see if you know where it should go if installed in the proper location
A fire needs four factor to continue existing, oxygen, fuel, heat and a combustion chain reaction to sustain the fire (the fourth element is why a fire is so hard to start, at the beginning of the fire it is not present, despite the first 3 element being present in abundance). This fire extinguisher act mainly on the chain reaction, with minor contributions by removing some free oxygen and some heat. Potassium nitrate (KNO3) is thermally decomposed into its highly reactive ions (K+ and NO3-). I assume inside the tube another reaction happens to form potatium hydroxide, or free K+ ions will find free OH- ions (potentially from the fire breaking down water vapor into ions) to form potassium hydroxide (KOH). This process will use free oxygen that would be otherwise accessible to the fire. It is a fairly minimal contributor to the fire extinguishing ability of the tube. The KOH keeps falling on the fire, and react with the fire free radicals to form potassium carbonate (K2CO3) and water. Potassium carbonate is non-flammable, therefore it help in stopping the free radical chain of a fire, helping it stop. This is the main factor involved here. Note: that tube wouldn't fight large heat-mass fire as there's not enough mass here to stop such a large fire long term. (it will reignite due to its latent heat once all KOH has been used). That's why you need powder fire extinguisher in that case (or straight water) to remove that heat by adding significant cold mass to the fire. That fire extinguisher is perfect for small kitchen fire A+++. I wouldn't recommend if your walls/house are literally on fire though. In that case you will need much much more KNO3 reacting that this tube can provide. Also, these system exist industrially to fight fire. They are very dangerous in case of fire as they will use all the oxygen available in the room and suffocate people (other type of dry fire fighting system are also dangerous like that). There's nothing to worry about that fire extinguisher however.

Good for small kitchen fires, wouldnt trust this for anything else though. Is it UL listed?
i'm impresed to👍🏼👍🏼👍🏼👍🏼👍🏼
That is a cool product. I bought a new napolean bbq and i am wondering what do i use to get the sticker off the lid without scratching it.

Wow that's crazy
Are they available in the US?
I sell them to Canada and US at mcmullanappliance.ca
Exactly how does this work? Is it just starving the fire of oxygen?
