Firefighter Classes Exercise: Perform The Angle: FDC Attach

Its not all flames office will experience fire section connections (FDC) inside their response place. For anyone divisions which happen to be addressing residential district and urban areas, you will come across them. FDCs are not only kepted for high-rise property. They will be available on single-story large frameworks, low-rise buildings, and parking garages.

FDCs shall be situated on the beyond the strengthening at a spot to get accessible by the flames department; this can be by top entry from the building. Some houses may have the FDC operating away from the building and standing by yourself like a pressure-reducing valve by the street. No matter the location, they’ve been made to let the flame department to provide liquid internally for interior surgery.


There are 2 forms of FDCs: threaded and storz. The storz means would be just one inlet of either 4, 5

or 6 ins, according to framework by itself in addition to department’s standards with regards to their regional building laws. Using storz are a sexless coupling, there is absolutely no challenge that may take place when linking excluding broken lugs on the coupling and/or coupling not completely spherical and somewhat oval, which makes it hard to connect.

Problems that occur using the threaded FDC will be the seizing of this couplings on the FDC. Feminine couplings exist on every FDC and enable the male coupling to-be threaded in to the FDC. With exposure to weather condition, soil, and corrosion, the couplings regarding FDC can get up-and never be complimentary adequate to twist. At these times, a man thread are not linked.

One method to lessen this issue is always to rotate the hose when you look at the reverse movement about five or six occasions. This twisting of this hose pipe allows the hose to untwist within the correct or clockwise path while in addition allowing the male coupling becoming threaded to the feminine coupling without rotating the female coupling.

Preplanning may also lessen this dilemma by examining to find out if the couplings spin freely or perhaps not. Should they try not to, the house or property holder should be informed to mend the problem.

Devices required: Two 2 ?-inch period of hoses, spanner wrench, entry to an FDC

Objective: to apply securing the FDC using the perspective process because of the hose pipe


  1. Locate the FDC on the strengthening. Decide whatever FDC (bond or storz.)
  2. Eliminate the hats through the FDC.
  3. Search inside feminine coupling to spot any dust or obstructions inside the house.
  4. Or no rubbish or dirt discover around, use the spanner wrench to clean it.
  5. Grab one 2 ?-inch hose and twist they 5 to 6 occasions during the counterclockwise
  6. Starting with the leftover 2 ?-inch feminine FDC coupling, make thread relationship with the line toward FDC and untwist it heading clockwise to the right.
  7. When the line is threaded in to the coupling, utilize the spanner wrench to tighten up the coupling.
  8. Duplicate alike for your various other FDC coupling about right side.
  9. Use a bit of webbing or rope to secure the two hoses with each other.


  1. Threaded FDC couplings can seize and call for the hose pipe to get linked by twisting the line into the reverse direction.
  2. Start with the remaining FDC coupling to present the room to untwist the hose off to the right both for FDC connections.

Tag van der Feyst has been in the flames provider since 1999 and it is a regular firefighter in Ontario, Canada. He could be a worldwide teacher teaching in Canada, the United States, and Asia, as well as FDIC. Van der Feyst try an area stage suppression teacher the Pennsylvania condition flames Academy. They are in addition top honors writer of Residential flame save (flames manufacturing Books & movie).
