When a leak is detected in a fire hose during pumping operations and the fire hose cannot easily be replaced, a _____________ may be used to temporarily stop the leak.

In the context of a leak in a fire hose during pumping operations, using a hose jacket is a suitable solution for temporarily stopping the leak. A hose jacket is specifically designed to fit around the compromised section of the hose, providing a protective layer that can contain the flow of water and prevent further leakage. This method is effective because it reinforces the damaged area, allowing operations to continue with reduced risk of losing water pressure or volume.

Using a hose jacket allows firefighters to maintain operational capabilities without needing to immediately replace the entire hose, which may not be feasible in a high-pressure situation. It is important that the hose jacket is secure and properly fitted to ensure it effectively minimizes the leak.

Other options, while they may serve different purposes, do not directly address the issue of sealing a leak in a hose. A hose clamp may be used in other types of connections or repairs, but it might not provide a comprehensive solution for the larger and more flexible fire hose material. A fire blanket is intended for a different purpose—primarily for extinguishing small fires or protecting individuals. Finally, a patch kit could be used in some scenarios but is not as universally effective or practical as a hose jacket for this specific situation.
