The Mechanical code OSHA and Health dept. set limits on the temp. under
these hoods. Typically about 100'F with occasional 120'F. Hood chem systems
still tend to use 212'F release links, unless there is a lot of open flame.

Subject: RE: Hibachi hoods and sprinklers
286's? I would hope the ceiling temp surrounding the hood would never
get any where near the 165 temp. We had to use high temp heads near the
exit path for some older style pizza ovens as the blast of heat released
when the door was opened could fuse the 165 heads but they were not
exhausted at that spot.
But the open grilles are highly ventilated and the ones I've seen are
all protected with dry chem. Considering the cook is standing over the
grille the whole time he is cooking, I would hope that the temp would
not be anywhere near the 165 deg. temp. let alone needing a 286.
Go out to dinner and take an infra-red temp gun and shoot some real-life
temperatures just for research. Oh yeah and try and enjoy the dinner.
I'd be curious to find out what the release temps are for the dry chem
systems within the hood.

Subject: Hibachi hoods and sprinklers
Does anyone have any experience with sprinklers close to hoods in
Hibachi restaurants?
We frequent one locally with 165 degree sprinklers and the sprinklers
have never gone off. We just finished one and the hood people are saying
that we better use 286 deg heads anywhere close to the Hibachi hoods.
Any comments/advice?
