Not where I really want to be
Got this email from an architect I have worked with before on some large projects. Looking for input on this one.

XXXXXX is considering adding outdoor tire storage (not high-piled), covered against a couple of the exterior walls of the existing shop building which is for tractor repair and tire shop. This would be open storage of metal building structure with a roof on it (max height 18’+/-) and not structurally attached but flashed to the existing building walls. My question is about fire sprinklering this area. According to section 315.3.1 of the 2009 ICC Fire Code, if the building is fire sprinklered then this area would be required to be fire sprinklered. Is this indeed the requirement and is there any amendments by Pennsylvania or locally that would affect this requirement. Obviously, the client would rather not sprinkler it. If it is required when the storage is directly adjacent to the existing building, is there a minimum distance from the building that this storage could be constructed without fire sprinklering? Also, for your information, one of the walls to which this structure would be attached is a precast concrete wall which would garner us at least a 2 Hr fire rating and the other is metal building construction. I’m not sure if that has any bearing on the situation based solely on the section 315 in the fire code but maybe ist does elsewhere that I’ve missed. I appreciate any assistance that you can provide me on this.

No, there are no amendments but we have to start with the IBC first.
 
So is the building already sprinkled??

If so need a little separation in order not to sprinkle the canopy

If not sprinkled follow 315 IFC
 
Should have asked how many sq ft

Should have read all of 315

Same answer though, building not sprinkled canopy normally does not kick in retrofit

This kind of says what nfpa 13 says

315.3.1 Storage beneath overhead projections from buildings. Where buildings are protected by automatic sprinklers, the outdoor storage, display and handling of combustible materials under eaves, canopies or other projections or overhangs is prohibited except where automatic sprinklers are installed under such eaves, canopies or other projections or overhangs.

Tire storage would be limited to 6 feet in height before becoming high piled storage. he may have different options that would allow him the flexibility that he is seeking. As far as I know, the fire code does not have a limitation on the number of areas that are considered high piled as long as the separations are maintained in accordance with IFC section 3206.2 thru 3206.3.2
 
We have a tire recycling center; and they plan to start breaking down the materials. You might start with State laws before you get into local building codes. Uncle Bob
 
The building is a metal building and the lean-to will be attached via flashing but be self supporting. The building is sprinklered, therefore, the new area will be sprinklered too. The architect and I agree on the sprinkler requirement.
 
Yep building sprinklered canopies are sprinkled when have storage under them

How many sq ft????? Of canopy

If structure has no walls you may need to look at draft curtains to contain heat and activte enough heads to suppress fire.

Another option maybe to skirt the upper portion of the exterior wall lines to help hold the heat in to activate the sprinklers

Probably the best course of action if the lot can support it.

Any idea on the hydraulics of the existing system? Could it easily support an expansion, or would they have to upgrade their existing equipment?
 
IFC 2006

2501.1 Scope.

Tire storage in buildings shall also comply with Chapter 23.

HIGH-PILED COMBUSTIBLE STORAGE






Look right above this line (Rubber Tires High Haz)

2303.7 Classification of plastics.

​


Plastics shall be designated

​
as Group A, B or C in accordance with this section.

Then see table 2306.2 High Hazard

Draft curtains are not needed the fire plume spreading out under the roof will be sufficient for sprinkler activation
 
If the exterior wall is already 2 hr....what would it take to make it a fire wall and seperate building? And then what would it take to not sprinkler it?

How many tires kicks in the 13 system?...Really curious....."2nd building" would (or could)be under any threshold in the building code that requires sprinklers....

Canopy with storage under it , attached to a sprinkled building kicks in sprinklers for the canopy
