The firefighter controls both couplings b. A donut hose roll is advantageous because: A straight roll of hose leaves one coupling exposed for easy access.
CHAPTER 15 Fire Hose Appliances and Nozzles Knowledge
This allows for the protection of the male threads.
It minimizes tangling and can help keep the hose in.
The female end is exposed and the male end is protected in the center of the roll. Consists of metal frame with two or more rollers; The d ouble roll / donut roll/dutch roll method effectively avoids twisting and knotting during the rolling. A donut hose roll is advantageous because:
The doughnut role allows access to both ends of the couplings without rolling out the entire hose. The donut roll is easily secured by a large cut piece of truck. Among the choices given, the correct advantage of a donut hose roll is that it's easy to carry. It is easier to make than a straight roll c.
A donut hose roll is advantageous because:
This type of roll is. A donut hose roll is advantageous because: The firefighter controls both couplings. Both couplings are protected on the inside of the roll.
What is the purpose of lugs on a fire. B.it is easier to make than a straight roll. Similar to how properly inflated tires on a car create less energy dissipation and offer better gas mileage, a donut hose roll is designed to retain its shape and minimize energy losses during. You can roll this hose quickly, but it will often overlap at the ends, and most firefighters will lay the hose flat and step on it to compact the donut.
A donut hose roll is advantageous because:
This method of packing a fire hose involves rolling it in a way that forms a donut. It is more compact than a twin donut roll. This type of hose roll is easier to. Prevents damage to hose that can occur when dragged over sharp corners ;
Can be used for protecting rope from similar edges It is easier to make than a. The straight roll is advantageous because it keeps the hose organized and ready for rapid deployment during emergencies. It is more compact than a twin donut roll d.
A donut hose roll is advantageous because it allows for more efficient use of space during transport and storage and better shape retention.
The street roll is used more for storage of the hose and is less useful on the. The hose is folded in half, then the folded end is rolled towards the open ends. The male coupling end of the hose finishes on the inside of the female coupling. This method is often used when the hose is deployed directly from the roll.
A.both couplings are protected on the inside of the roll.
