The 2015 IFC states: LUMBER YARDS AND AGRO-INDUSTRIAL, SOLID BIOMASS AND WOODWORKING FACILITIES 2809.5 Fire protection. An approved hydrant and hose system or portable fire-extinguishing equipment suitable for the fire hazard involved shall be provided for open storage yards. Hydrant and hose systems shall be installed in accordance with NFPA 24. Portable fire extinguishers complying with Section 906 shall be located so that the distance of travel from the nearest unit does not exceed 75 feet (22 860 mm).
To get that "approved hydrant and hose system" we'd typically have a layout showing the yard and anticipated loading. Take that to the local fire code official (FCO) and talk about what kind of flow is available (I've have gotten this from local water purveyor before meeting the FCO). If you only have 1500 gpm flow rate available at 20 psi for example, how many hydrants will have to be involved with how many pumpers for the required hose streams. We also talk about apparatus access through the yard and minimum aisle widths and turn radii so the owner knows there are stacking limitations. Some of the answers depend on how the local FD is equipped. I agree, this is not a building related issue and even if there were a building on site, providing adequate resources for fighting a yard fire is a totally different hazard from a building. Also, for industrial or high flow rate areas I typically spec out the American Flow Control's American Darling Industrial hydrant with the 6" valve opening in lieu of the standard commercial hydrant with the 4.5 - 5" valve opening. The AFC American-Darling hydrant # is B84B-BB-5. These can typically deliver up to 4800 gpm through the 4.5" pumper connection at 100 psig. A lot of times we've just gotten hydrant spacing recommendations with no specific pressure or flow rates required. I guess most FDs have resolved that they will get what they get and do the best with that. Craig L.

Huge outdoor piles of stored wood products, engineered members mostly, some smaller amounts of dimensional lumber. We're trying to establish a fire flow for hydrants but there are no buildings of any size to benchmark and tables in the fire code are not of much use because they're based on building area and construction type. The fire load here is not in buildings ... [Steve Signature (3)] -------------- next part -------------- An HTML attachment was scrubbed...
