At the heart of every effective hoseline operation is an effective estimate of the hoseline stretch. Estimating the hoseline stretch requires that the company officer determine the proper length of the hoseline to reach the fire while also allowing 50 feet of hoseline for working in the fire area. Although training can improve firefighters’ ability to properly estimate the hoseline stretch, no firefighter is perfect, and mistakes can and will occur.

A mistake in the estimate of a hoseline stretch will most likely result in hoseline that is either longer than necessary, which may result in a messy pile of hose (often referred to as “spaghetti”) or in unwanted kinks in the hoseline. Although it is possbile that a stretch can be too long, firefighters can stretch and advance a hoseline that will come up short and not effectively reach the fire area. All firefighters must prepare to overcome these mistakes when faced with the possibility of an incorrect stretch, especially with a short hoseline stretch that does not reach the fire area.

When a short hoseline stretch occurs, firefighters have two options: stretch and advance a second hoseline or extend the length of the initial hoseline. The former can be a resource depleting operation depending on the staffing that is available, while the latter can many times be performed in a more timely manner and requires less staffing than stretching and advancing a second hoseline.

When firefighters try to overcome a short hoseline stretch by extending the length of the initial hoseline rather than stretching and advancing a second hoseline, the extension of the initial hoseline can be performed in two locations: the nozzle end of the hoseline or the apparatus end of the hoseline. Many times, when confronted with the need to extend the length of a hoseline, firefighters will use a hose clamp to stop the flow of water through the hoseline while the length of the hoseline is extended or the apparatus operator will completely shut down the hoseline at the apparatus pump panel while the length of the hoseline is extended. When a hose clamp is used to extend the length of a hoseline, the extension can be performed at either the nozzle end or the apparatus end of the hoseline.

To extend the length of a hoseline at the nozzle end using a hose clamp, firefighters should perform the following operation:

To extend the length of a hoseline at the apparatus end of a hoseline using a hose clamp, firefighters should perform the following operation:

You can also extend the length of a hoseline by completely shutting down the hoseline at the apparatus pump panel. When the water flow through the hoseline is stopped by taking this measure, you can again extend the length of the hoseline at either the nozzle end or the apparatus end of the hoseline. To perform this action, do the following:

To extend the length of a hoseline at the apparatus end of the hoseline by shutting down the hoseline at the apparatus pump panel, firefighters should do the following:

The operation to extend the length of a preconnected hoseline at the apparatus end of the hoseline can differ from a nonpreconnected hoseline because of the location of the apparatus discharge outlet to which the hoseline is connected. In the case of nonpreconnected hoselines, the hoseline is connected to an easily accessible apparatus discharge outlet on the side or rear of the apparatus.

Preconnected hoselines are typically connected to an apparatus discharge outlet inside the apparatus hosebed accessible only by a firefighter standing on top of the apparatus in the hosebed. Because these discharge outlets are usually inside the apparatus hosebed, the operation to extend the length of a preconnected hoseline at the apparatus end differs for a nonpreconnected hoseline. To extend the length of a preconnected hoseline to a discharge outlet inside the apparatus hosebed from the apparatus end of the hoseline by shutting down the hoseline at the pump panel, firefighters should do the following:
