What is the relationship between hose length and water flow rate
Layflat fire hoses are essential for firefighting—their flat design makes them easy to store and deploy. But to use them effectively, you need to master the right throwing and recycling methods. Below is a detailed, step-by-step guide for both processes.
How to Throw a Layflat Fire Hose
Throwing a layflat fire hose quickly and accurately ensures fast water delivery to the fire site. Follow these steps:
Step 1: Prep the Layflat Fire Hose by Rolling It
First, roll up the layflat fire hose properly. When rolling, slightly misalign the two hose interfaces (the ends used for connections). Next, fold the hose in half. Start rolling from the middle of the folded hose. Keep rolling tightly until the hose forms a compact disk. When you finish, the two interfaces will sit exactly on top of the disk—this makes connecting easier later.
Step 2: Throw the Fire Hose with Proper Hand Technique
Hold the rolled layflat fire hose with both hands. Use your forearms to swing the hose forward at a 45-degree angle. As you swing, release all fingers except your thumbs and index fingers. This lets the main body of the fire hose fly out smoothly. You’ll be left holding only the two interfaces—perfect for quick connections next.
Step 3: Connect the Fire Hose and Deploy the Water Gun
Once the hose is thrown, take action fast. Place one interface on the ground (if you need to adjust) or connect it directly to a fire hydrant, fire truck water outlet, or water distributor. Then, pick up the other interface and run forward quickly. While running, grab the fire hose water gun and attach it to the free interface. This way, you’re ready to start spraying water as soon as possible.
