Infrasound waves stop kitchen fires, but can they replace sprinklers?
arstechnica.comWhy the fuck would you want a sprinkler system in your house?
Do you want everything you own destroyed every time it goes off by accident?
Do you know how much worse a sprinkler system makes kitchen fires?
To provide more information than the others who responded: typical sprinkler systems are not automatically activated in response to a fire alarm. Each sprinkler head has a small glass vial filled with a liquid, calibrated to break at a certain elevated temperature (e.g 160 or 180 F). The flow of water starts when the glass breaks. So there has to be a significant fire near the sprinkler before it activates.
One weakness is that the glass vial is fragile. In some hotels you’ll see signs reminding guests not to hang clothes from the sprinkler head, as a clothes hanger could break the vial and activate the water flow.
let me help educate you. :)
Most common sprinkler type used in a residential setting is “wet pipe”: https://www.nfpa.org/news-blogs-and-articles/blogs/2021/03/2...
The sprinkler is “activated” if the ambient temperature around the sprinkler head is 40C, due to the little “wet pipe” in the sprinkler bursting. 40C is HOT. Basically - when your whole apartment is beginning to catch fire. It’s designed to save lives, not your things.
Newer (higher end) apartments will have the sprinkler itself hidden / recessed, this way the little wet pipe / vial can’t be accidentally damaged by force (when cleaning, painting, etc)
40c is miserable to be in, but it's not really that hot compared to fire or combustion. The record hot day in Phoenix was 50c; miserable but livable w/ precautions.
wet pipe burst temps are between 57c-75c .
While 40°C is hot, it is not insanely hot. Every summer temp goes easily above 35°C in my apartment for a number of days.
"By accident"? How do you think sprinklers work, exactly? You "accidentally" left the sauna door open and now the living room is 160F?
If it were a problem, you'd be hearing about it from apartment dwellers, since sprinklers are required in many (if not most) cases:

Shelves moving and people hanging suits on them come to mind.
Worse yet, you might not have a choice; the article notes that “sprinklers are already required in all new California homes built in 2011 and later.”
It's kind of funny that everyone's crapping on this comment when the poor value proposition of sprinklers in residential settings is exactly what enabled the investment to develop this system.
That's not how sprinklers work?
Have you ever lived in a place with sprinklers?
Do you actually think they go off when ever the highly sensitive smoke detectors detect you made your pizza extra crispy with the window closed.
Please enlighten us then, why do many countries require commercial kitchens have fire sprinklers if it's such a terrible and dangerous idea?
Most developed jurisdictions require commercial kitchens (and commercial spaces in general) to have fire suppression systems, not necessarily fire sprinklers. Water sprinklers are a common choice for fire suppression in many spaces because they're relatively cheap, but they're not the only option. A kitchen fire suppression system will generally be a wet chemical system that will safely blanket a grease fire while still being easy to clean off of food prep surfaces unlike dry chemicals.
