SFD hose is rolled into ___ for storage and into ___ to transport for repair
- A single roll
- A double roll
Hose is also rolled, when necessary, to ___
Purge air so that the hose will load more compactly
The single and double rolls are to be done with the hose ___
Stretched straight, without twists or turns, and laid flat on the ground
Hose rolling is usually a ___ operation and best performed from ___
- One-person operation
- The highest grade of land to the lowest to facilitate water drainage
A second member, when available, can expedite hose rolling by ___
Assisting with stretching and laying the hose
Hose must be ___ before rolling the hose and placing into storage
Cleaned and thoroughly dried
Single roll steps
- Facing the open end of the male coupling, grasp the coupling with both hands and roll it away from the body and tightly into the hose
- Continue to roll the hose until it reaches the female coupling
- Lay the roll on its side and stamp out any protruding coils
Double roll steps
- Grasp male coupling and carry it back to the female coupling. Lay it on top of the hose about 6’ from the female coupling. Walk back to the bight
- Roll the hose from the bight end
- The female coupling should stick out a foot or two beyond the male coupling
- Lay the roll on the side and connect the couplings (a layer of hose should protect the couplings)
- Secure with three lengths of heavy-duty twine. First through the center and between the couplings and the bight and between the two outermost layers of hose
- Final two spaced evenly and around the outermost layer
How to mark a hose that has been damaged for repair
- Tie a rag around the hose at the point of damage

- Butterfly method
Traditional method of unrolling hose
Grasp the outside coupling and push the rest of the roll away, allowing the roll’s inertia to unwind it
Disadvantage of the traditional method of unrolling hose
The male coupling at the other end could become damaged as it snaps downward against the ground
