What is the function of a booster hose?

A booster hose is primarily designed for providing limited flow, which is particularly effective in managing smaller fires. Its versatility as a roughly 1-inch diameter hose allows it to deliver sufficient water pressure and volume for tackling smaller blazes, making it ideal for situations like brush fires or vehicle fires where a heavy flow rate may not be necessary.

While options mentioning sustaining heavy flow, extinguishing wildfires, or protecting against electrical fires point to different types of hoses or tools utilized in fire suppression, they do not represent the booster hose's function accurately. Booster hoses do not typically support high flow rates as they are not intended for large-scale firefighting operations. Instead, they fill a crucial niche for quick response scenarios where rapid deployment and sufficient flow for minor incidents are required.
