fire sprinkler in kitchen exhaust ducts

fire sprinkler in kitchen exhaust ducts

fire sprinkler in kitchen exhaust ducts

(OP)
Do we require fire sprinkler as protection in kitchen exhaust ducts for high rise hotel buildings.As i understand NFPA13 does not recommend if the duct is connected to a listed hood .Can somebody explain if NFPA101 AND NFPA 96 would require otherwise?

RE: fire sprinkler in kitchen exhaust ducts

if you are protecting the cooking applaince with the fire sprinkler system than you would protect the duct work also with the sprinkler system  nfpa   7.9, 7.9.3 2002 edition

but if there is a fixed pipe system than that should be protecting the duct and you do not need the sprinklers also.  

RE: fire sprinkler in kitchen exhaust ducts

First the NFPA 96 is a guide and NOT the code. You will need to check your local jurisdiction whether fire sprinkler in grease ducts are required.

Taken from NFPA 13, 2007 ed. 7.10.3.4.1 Where ducts do not exceed 75 ft (22.86 m) in length and the entire exhaust duct is protected in accordance with UL 300, Standard for Safety Fire Testing of Fire Extinguishing Systems for Protection of Restaurant Cooking Areas, sprinkler(s) [or automatic spray nozzle(s)] shall not be required.

In all the high-rise grease exhaust projects I worked on, aprinklers were ALWAYS used in the grease duct.

I was told be the local fire marshal that if my project was for a 1 story building than NO spinklers would be required. I have yet to design for a 1 story building.

Check with your local jurisdiction to see if sprinklers are required. If the building dept. cannot assist you, go check with the fire dept.
