消防员训练钻：扭曲：FDC联系

并非每次消防部门都会在响应区内遇到消防部门联系（FDC）。对于那些覆盖郊区和城市地区的这些部门，您将遇到它们。FDC不适用于高层建筑。他们将在单层大型结构，低层建筑和停车车库中找到。

FDC将位于建筑物外，在消防部门可访问的地方;这可能是由建筑物的前门。一些建筑物将使FDC远离建筑物，单独站立，如街道的减压阀。无论位置如何，它们都旨在允许消防部门为内部提供内部操作。

There are two types of FDCs: threaded and storz. The storz type will be a single inlet of either 4, 5, or 6 inches, depending on the structure itself and the department’s specifications for their local building code. With the storz being a sexless coupling, there is no problem that can occur when connecting except for damaged lugs on the coupling or the coupling not being perfectly round and somewhat oval, making it difficult to connect.

通过螺纹FDC可以发生的问题是FDC上的耦合拍摄。每个FDC都存在女性联轴器，并允许雄性耦合拧入FDC。通过暴露于天气，污垢和生锈，FDC的联轴器可以抓住并且不足以旋转。发生这种情况时，无法连接雄线程。

One way to alleviate this problem is to twist the hose in the opposite direction about five or six times. This twisting of the hose allows the hose to untwist in the right or clockwise direction while at the same time allowing the male coupling to be threaded into the female coupling without spinning the female coupling.

预先打算还将通过检查耦合是否自由旋转来缓解此问题。如果没有，则需要通知业主，以便他们可以解决问题。

Equipment needed:Two 2 ½-inch length of hoses, spanner wrench, access to an FDC

目标：用软管使用扭曲方法练习固定FDC

钻头：

1. Locate the FDC on the building. Identify the type of FDC (thread or storz.)
2. Remove the caps from the FDC.
3. Look inside the female coupling to spot any debris or obstructions inside.
4. If any garbage or debris found inside, use the spanner wrench to clean it out.
5. 在逆时针拍摄一台2½英寸的软管并将其扭曲为5到六次
6. Starting with the left 2 ½-inch female FDC coupling, make the thread connection with the hose to the FDC and untwist it going clockwise to the right.
7. Once the hose has been threaded into the coupling, use the spanner wrench to tighten the coupling.
8. Repeat the same for the other FDC coupling on the right side.
9. Use a piece of webbing or rope to secure the two hoses together.

关键点：

1. 螺纹FDC联轴器可以通过沿相反方向扭转软管来抓握并要求软管通过扭转软管。
2. Start with the left FDC coupling to provide the room to untwist the hose to the right for both FDC connections.
