The Front Bumper Donut Roll Load
Many of the pumpers manufactured in recent years are equipped with pre-connected handlines mounted in the front bumper. These lines are usually small in size (1” to 1-3/4”) and are most commonly found in lengths ranging from 50’ to 150’. They are very effective for fighting the smaller type fires such as vehicles, grass, rubbish, and dumpsters, etc.
The hose tray for this type of line is usually small and deep, making a flat load somewhat difficult to deploy. The hose sometimes has a tendency to hang up in the hose tray because of its depth. Furthermore, the line must be stretched out to its entire length before it can be charged.
The deployment of this very handy line can be made easier using the concept of the donut roll. The donut roll hose load allows the line to be cleared from the hose tray quickly and stretched out in less distance, with either two or no bends in the hose depending on the length of the line.
The 50’ load consists of a single donut roll placed upright in the hose tray. The female coupling on the hose connects to the discharge, and the male coupling gets the nozzle. To deploy the 50’ line, simply remove the roll from the tray, holding on to the nozzle, and drop the roll on the ground. The line can then be stretched out either by advancing with the nozzle or by pulling back fast on the hose, flaking the line out.
The 100’ load consists of two 50’ donut rolls placed upright in the hose tray. The first roll is placed in the tray and connected to the discharge with the female coupling. The male coupling side of the first roll is left with about a 3’ tail hanging to the side. The second 50’ roll is then placed in the tray and connected to the 3’ tail of the first roll by its female coupling. The connection now forms a loop which will be used to stretch the line. The male coupling of the second roll gets the nozzle.
Advancing the 100’ is also very simple. The nozzle is first placed to the side of the tray on the bumper. The firefighter then grabs the looped part of the hose load with one hand, and pulls the rolls and drops them to the ground with the other hand. From this point the line can be advanced by pulling the loop and holding on to the nozzle. The 100’ line will deploy very easily within 50’ and with only two bends in the hose. At this point the firefighter will have 50’ in hand that can be advanced if needed.
