The fire department connection (FDC) shall not be greater than 50 feet from a fire department access road. Water mains that are 6 inches in diameter and serving a fire hydrant shall not exceed 350 feet in length. Show an NFPA 13 FDC location within 200 feet of a fire hydrant as the truck travels.
Regardless of the average spacing, fire hydrants shall be located such that all points on streets and access roads adjacent to a building are within the distances listed in Table C105.1. For SI: 1 foot = 304.8 mm, 1 gallon per minute = 3.785 L/m. Reduce by 100 feet for dead-end streets or roads.
20 Μαΐ 2019 · For years on my code calls I have asked the Authority Having Jurisdiction what the maximum distance the nearest hydrant is allowed to be away from a building's fire department connection. I get answers that range from 50 feet to 400 feet or even more.
Where more than one fire hydrant is required, the distance between required fire hydrants shall be in accordance with Sections C103.2 and C103.3.
This particular appendix gives one methodology based on the required fire flow that fire departments can work with to set a policy for hydrant distribution around new buildings and facilities in conjunction with Section 507.5.
Where new water mains are extended along streets where hydrants are not needed for protection of structures or similar fire problems, fire hydrants shall be provided at spacing not to exceed 1,000 feet to provide for transportation hazards.
FIRE HYDRANT TEST. A non -sprinklered building hydrant flow test will require a “Single Hydrant Test” of the closest hydrant by the apparatus travel distance. This test will show how much water is available to the apparatus from the hydrant for suppression of the structure.
