The 2016 NFPA 13 handbook states that canopies less than 4' are not required to have sprinklers, regardless of construction type, unless combustibles are stored under them. Projections 2' or more require sprinklers, regardless of construction type, if there are combustibles stored below it.

It sure seems to me like we don't have to install sprinklers under *combustible* overhangs 4 ft or less as long as there is no storage underneath. It doesn't say this explicitly (it just doesn't require sprinklers there, it doesn't specifically omit them), so maybe there is a reason for that? -Skyler On Tue, Oct 5, 2021, 6:40 PM James Crawford via Sprinklerforum < [email protected]> wrote: > We have been discussing exterior projections in the office and with an > AHJ on when sprinklers are required. > > Section 8.15.7.1 Unless the requirements of 8.15.7.2, 8.15.7.3. or > 8.15.7.3 are met, sprinklers shall be installed under exterior > projections exceeding 4'-0" in width. > > Section 8.15.7.5 Sprinklers shall be installed under exterior > projections greater than 2'-0" wide over areas where combustibles are stored. > > Canopy is less than 4'-0" in width, No vehicle storage, > non-combustible construction, not a corridor, so all items are met for > 8.15.7.1, no sprinklers required. > > But 8.15.7.5 seems to requires them because the canopy is over 2'-0" > > Normally we worked on the assumption less than 4'-0" and > non-combustible, no storage, no sprinklers required and the 2'-0" was > for combustible construction, over 2'-0" you required sprotection. > > What are we missing > > Thank You > > James Crawford > Phaser Fire Protection Ltd. > Phone 604-888-0318 > Cel: 604-790-0938 > Email [email protected]<mailto:[email protected]> > Web: > www.phaserfire.ca<https://urldefense.com/v3/__http://www.phaserfire.ca > __;!!Lat9tvSZzw!2966oXlOCeWJFkrAPJWVub7_nW9I5W6w71dVLCjboahCHUcxkKS9R2 > anwqvBWC0VLYZx$ > > > _______________________________________________ > Sprinklerforum mailing list > [email protected] > > https://urldefense.com/v3/__http://lists.firesprinkler.org/listinfo.cg > i/sprinklerforum-firesprinkler.org__;!!Lat9tvSZzw!2966oXlOCeWJFkrAPJWV > ub7_nW9I5W6w71dVLCjboahCHUcxkKS9R2anwqvBWKummc6-$ > _______________________________________________ Sprinklerforum mailing list [email protected] https://urldefense.com/v3/__http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org__;!!Lat9tvSZzw!2966oXlOCeWJFkrAPJWVub7_nW9I5W6w71dVLCjboahCHUcxkKS9R2anwqvBWKummc6-$ _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
