The FDC shall have a clear working space of 36 inches around the FDC and an unobstructed height of 78 inches. This clear space shall be maintained. system demand. For NFPA 13R Systems, provide one 2.5-inch national hose coupling inlet.
Most authorities having jurisdiction (AHJ) will expect at least 36-inches clearance in front of the extinguisher as long as it is still visible. They “borrow” this 36-inch clearance measurement from NFPA 70-2011, Article 110.26 for electrical control panels.
NFPA 13 Standard for the Installation of Sprinklers simply requires an FDC to supplement the system if needed. In the case of a NFPA 13 automatic fire sprinkler systems, the standard requires a single two x 2 ½ in. FDC for all systems with risers greater than 3 in.
The maximum distance from a fire hydrant to a fire department connection (FDC) supplying fire sprinklers and/or standpipes shall not exceed 100 feet, as measured by an approved route. An approved route is defined as an unobstructed path of travel on which hose can easily be laid.
901.11 Clearance Around Fire-Protection Systems and Equipmen
A minimum 3-foot (914 mm) clear space, on a minimum of two sides, shall be maintained for access to fire protection equipment, including control valves and control panels.
A clear space of 3 feet (914 mm) must be maintained in front of and to either side of wall-mounted FDC's [Figure 912.3. 2(1)] and around free-standing FDC's [Figure 912.3. 2(2)] to allow easy hose connections to the fitting and efficient use of spanner wrenches and other tools needed by the appa- ratus engineer.
Each extinguisher shall be located in conspicuous, readily accessible location. Fire and Rescue NSW recommends that a surrounding clearance of a minimum of 1000mm be maintained around each extinguisher.
A clear space of 3 feet (914 mm) must be maintained around hydrants (see Commentary Figure 507.5. 5) to allow easy hose connections to the hydrant and the efficient use of hydrant wrenches, spanner wrenches and other tools needed by the apparatus engineer.
Class I standpipe hose connections shall have a minimum clearance of 8 inches (2032 mm) measured from the center of the hose connection in at least one plane to permit the fire department the option of attaching a wye fitting to use two 1-1/2 inch (38 mm) hoses in lieu of one 2-1/2 inch (63 mm) hose.
And while they may look very similar to FDCs, never forget these devices' extremely different functions: FDCs are for putting water into a standpipe or sprinkler system, while wall hydrants dispense water out to firefighters.
FDCs shall be installed so that the centerlines of the inlets are located at a minimum height of 18” and a maximum height of 48” above the adjacent finish grade. FDCs shall be installed on the system side of the indicating valves.
According to NFPA 13, the FDC should be installed on the fire sprinkler system's side of its water supply check valve. When responding to a fire, firefighters hook the female end of their hose to a pumper truck and connect the male end of the hose to one of the FDC's female swivel connections.
The NFPA 72 "covers the application, installation, location, performance, inspection, testing, and maintenance of fire alarm systems, supervising station alarm systems, public emergency alarm reporting systems, fire warning equipment and emergency communications systems (ECS), and their components." Federal, state, and ...
Clearance at Fire Alarm Pull Stations
Do not obstruct access to and visual contact with the fire alarm pull station. There must be a minimum of 36 inches of clearance, in a semi circle shape, from the pull station.
The employer shall distribute portable fire extinguishers for use by employees on Class A fires so that the travel distance for employees to any extinguisher is 75 feet (22.9 m) or less.
The Fire Sprinkler Code, 2022 (NFPA 13, 2022) is a code produced by the National Fire Protection Association (NFPA). This document provides the foundation for many state and city codes. The NFPA 13, 2022 combined with local jurisdiction amendments form the state codes.
An FDC is a connection through which a fire department can pump water into the sprinkler system, standpipe, or other system within a building. This provides additional water to supplement the building's existing water supplies, which is a huge aid in the fire extinguishing process.
The minimum clearance required from combustible material when a single wall vent connector is used to vent a warm air furnace is 6 inches.
FDCs are typically located on the outside of the property they protect, but can sometimes be completely separated from the building altogether. Such FDCs are known as freestanding or sidewalk FDCs. In any case, NFPA 13 requires FDCs to be located on the street side of the property (if possible).
Extinguishers also need to be installed in places where they're visible, but if an obstruction is unavoidable then there needs to be a sign provided to indicate the extinguisher's location. Extinguishers need to be installed at least 4 inches off the ground up to a maximum of 5ft.
Make sure fire hydrants have a three-foot area clear of debris and obstructions. In case of a structural fire, firefighters will need to quickly access the hydrant for water supply. An obstruction of fencing, tree branches, bushes, weeds, or brush may cause a delay as firefighters try to get water to extinguish a fire.
Detached One- and Two-Family Dwellings. Fire Hydrants shall be within five hundred (500') feet of the most remote portion of buildings, measured by vehicular access and building perimeter. The maximum distance between fire hydrants shall not exceed 800 ft.
A minimum 3-foot clear space around the circumference of the fire hydrant shall be provided and maintained at all times. Low height groundcover plants and grass may encroach upon the three foot clear radius as long as it does not deter or hinder the fire district to utilize the hydrant.
NFPA 72 refers to fire alarm pull stations as “manual fire alarm boxes.” The code requires that the travel distance to the nearest pull station on a given floor must be no more than 200 feet. So, the larger the building and the longer its hallways, the more pull stations will be required.
An exit access must be at least 28 inches wide at all points. Where there is only one exit access leading to an exit or exit discharge, the width of the exit and exit discharge must be at least equal to the width of the exit access.
