Level 1-Includes the following: emergency lighting, exit signs, fire alarm, sprinkler alarm, and detection systems, fire pumps where backup power is required, controls for smoke control equipment required by the Building Code, elevator car lighting. In addition to these requirements, the applicant is advised to contact the San Francisco Department of Public Health at (415) 252-3900 for their requirements as the designated Hazardous Materials Unified Program Agency.Įmergency Power Supply System (EPSS): A complete functioning EPS system coupled to a system of conductors, disconnecting means and over-current protective devices, transfer switches, and all control, supervisory, and support devices up to and including the load terminals of the transfer equipment needed for the system to operate as a safe and reliable source of electric power. This document is not all-inclusive of all requirements for fuel installations, and it is the responsibility of the designer to research the applicable codes.

This checklist shall be prepared by the design professional and shall be stamped and wet-signed. This checklist is designed to assist designers, installers, plan reviewers, and field inspectors. Outdoor fuel installations will require further information. Purpose: This checklist has been developed primarily for fuel installations in buildings.
#FPE FIRE SPRINKLER DESIGN SF BAY AREA CODE#
Extended coverage sprinklers have a water distribution radius of a little over 10 feet, so they can be spaced approximately 20 feet apart.Reference: Documents referenced for this bulletin are the current adopted editions of the following: San Francisco FireĬode (SFFC), including Section 1203 San Francisco Building Code (SFBC) San Francisco Mechanical Code (SFMC) NFPA 13, Installation of Sprinkler Systems NFPA 37, Stationary Combustion Engines and Gas Turbines NFPA 30, Flammable and Combustible Liquids Code California Electrical Code San Francisco Electrical Code NFPA 110, Emergency and Standby Power Systems NFPA 704, Standard System for the Identification of the Hazard of Materials for Emergency response. In these cases, extended coverage sprinkler heads can be installed to increase the spacing between heads. In some circumstances, standard distribution sprinkler heads will not provide enough coverage. The minimum 1" is typical however, concealed, recessed, and flush sprinklers may be mounted less than 1" from the ceiling and shall be installed based on their listing. Minimum Distance Between Sprinklers: typically 6'-0".ĭistance from Ceiling: minimum 1", maximum 12" for unobstructed construction. Maximum Distance from Wall: half (1/2) of the maximum distance between sprinkler heads. (Plastic Processing, Chemical Spraying, Metal Extruding, Printing, Varnishing, Painting, etc.) (Mills, Manufacturing, Processing, Machine Shops, Repair Garages, Post Offices, Bakeries, Wood Machining and Assembly, Auto Parking, etc.)
(Office, Educational, Religious, Institutional, Hospitals, Restaurants, Clubs, Theaters, etc.) Actual design of a sprinkler system MUST be done by a Professional Engineer for each project. This table shall be used only as a tool for architects. The table below shows sprinkler spacing requirements based on NFPA 13. Storage must be kept at least 18" below the sprinkler deflector. Therefore, building owners must ensure that all storage and objects in the room remain 18" below the sprinkler deflector as shown in the image below. Water distribution for standard pendant sprinkler.Īccording to NFPA 13 (2016) 8.5.6.1, unless certain requirements are met, the distance between the deflector and the top of storage shall be at least 18 inches. Please note, that the throw of a sprinkler should not be used for sprinkler spacing - local codes determine spacing requirements. Refer to the manufacturer data for specific throw data. This is a general depiction of sprinkler throw and should not be used to determine sprinkler spacing. It is useful to understand how objects within this distribution area can alter the throw and disrupt the ability of the sprinkler to extinguish a fire. The diagram below shows the water distribution for standard pendant and upright sprinkler fixtures. Second, they must be located so that the water that is discharged from the sprinkler is not disrupted or affected by construction elements such as beams, trusses, or soffits. First, sprinklers must be located so they are within the hot-gas layer that develops near the ceiling during a fire because activation occurs when the sprinkler head reaches a certain temperature. There are two main criteria for the location of sprinkler heads.
