Firefighter Instruction Exercise: Carry Out The Twist: FDC Get Together

Don’t assume all fire section will discover flames division associations (FDC) in their response location. For all departments being cover residential district and urban areas, you will confront all of them. FDCs are not just booked for high-rise property. They will be available on single-story large buildings, low-rise houses, and vehicle parking garages.

FDCs might be situated on the outside the strengthening at a spot becoming obtainable by the fire office; this may be from the front entrances of this building. Some property are going to have the FDC situated from the strengthening and waiting alone like a pressure-reducing device of the road. Regardless of the area, these are generally made to allow the flame department to produce h2o inside for inside procedures.


There are two main types of FDCs: threaded and storz. The storz means might be one inlet of either 4, 5

or 6 inches, according to construction it self together with department’s specs because of their local building signal. With the storz getting a sexless coupling, there’s no problem that may occur whenever hooking up excluding wrecked lugs regarding coupling or even the coupling not completely circular and rather oval, which makes it difficult to connect.

Problematic that may happen making use of the threaded FDC will be the seizing on the couplings throughout the FDC. Feminine couplings exist on every FDC and enable a man coupling become threaded in to the FDC. With subjection to weather, dirt, and corrosion, the couplings from the FDC can take up and never be cost-free sufficient to spin. At these times, a man bond can not be linked.

One way to reduce this issue is always to rotate the hose pipe within the reverse movement about five or six occasions. This twisting of hose pipe permits the hose to untwist from inside the right or clockwise movement while in addition enabling the male coupling are threaded into the feminine coupling without spinning the female coupling.

Preplanning will even reduce this issue by checking to see if the couplings spin easily or not. As long as they cannot, the home owner must be notified to enable them to mend the problem.

Equipment needed: Two 2 ?-inch length of tubes, spanner wrench, usage of an FDC

Goals: to train securing the FDC with the angle technique making use of the hose


  1. Find the FDC regarding building. Determine the type of FDC (thread or storz.)
  2. Get rid of the hats from FDC.
  3. Appear inside female coupling to identify any debris or blockages inside.
  4. If any garbage or particles receive around, utilize the spanner wrench to completely clean it out.
  5. Just take one 2 ?-inch hose and twist it 5 to 6 days when you look at the counterclockwise
  6. You start with the kept 2 ?-inch feminine FDC coupling, result in the thread relationship with the line on the FDC and untwist it heading clockwise on the right.
  7. As soon as the hose pipe has been threaded into the coupling, use the spanner wrench to tighten up the coupling.
  8. Recurring equivalent the different FDC coupling on the right side.
  9. Incorporate an article of webbing or line to secure the two tubes along.

Key Points:

  1. Threaded FDC couplings can get and need the hose becoming linked by twisting the hose pipe into the contrary way.
  2. Start with the remaining FDC coupling to deliver the space to untwist the line off to the right for FDC connections.
