Before the LDH was the main supply line, we used 2.5 and 3inch hose for supply. Most fire departments laid in or out and allmost always applied the clamp. Now with LDH the primary supply line in the American Fire Service, we just about in some places forgot about the clamp. The clamp is just as important today, as it was twenty or thirty years ago. The clamp keeps photos of your supply bed charged on FB. The clamp allows your driver to do other things and first utilize tank water. The clamp allows the hydrant firefighter to send water/charge the hydrant and then advance down to the scene. Once at the scene this is an additional firefighter that may assist the driver with final hook ups and release the clamp. So many times when the clamp is not applied, the hydrant firefighter is waiting to charge and delaying this firefighter from advancing down to the scene.

An additional note is that it sometimes takes two firefighters to break loose the LDH storz and the driver is all alone. If they were to clamp and allow hydrant firefighter to charge and move down; this would give the driver an additional firefighter to assist with the disconnect of the LDH storz.

So why not use the LDH CLAMP? Have you trained on it? Do you know where it is? Do you clamp everytime?

Has your FD ever charged the supply bed?

  1. As stated above the quick application of the hose clamp allows the hydrant firefighter to complete the hook-up and send water to the engine. A good practice to follow is to have someone designated (Officer or Driver) as the person who applies the clamp when the engine arrives on scene. The hydrant firefighter is trained to turn on the hydrant when he has completed his hook-up. There is no confusion over hearing the wrong air horn, whistle or other usual signals to tell the hydrant man to turn on the hydrant. If the hose lay was short the hydrant man can look to see if the clamp is place before opening the hydrant.

    The main goal should be to get the water to the engine without hesitation. The engine company working together, with everyone doing their part can make this process a simple and effective task. I have used this method in the past and found it works very well.

  2. Like everything else, training is key. My first experience with the type of clamp above was a dismal failure during promotional testing. That one episode convinced me they were junk and not to be trusted. Later, someone lubricated it properly (it was dry the first time) and while I was trying to make a point about how worthless the Herbert Hose Clamp was…I only proved my ego was worthless. Worked perfectly. I learned once again two constants in the Fire Service: Train on everything and Egos eat brains. Good Post

  3. While I’m a fan of the process described above, I’m not a big fan of the 5″ clamp itself. In our dept., we have LDH manifolds on each rig (5″ and x2 2.5″ discharges) that the DE hooks into before hooking into the pump with a 5″ pony section. This, in effect, serves as our clamp, allowing the line to be charged quickly. To me, this is a better way to go, as it also allows additional supply lines to be connected.
