Which of the following is NOT a common hose load for preconnected attack lines?

Preconnected attack lines are critical for quick response and effective firefighting, and they often utilize specific hose loads for efficiency and ease of deployment. The circular hose load is not commonly used for preconnected lines because it does not facilitate the rapid unrolling and extension of the hose during emergency situations.

The Minuteman load is designed for quick deployment, allowing firefighters to pull the hose while it remains secured, making it effective for initial attack lines. The flat load is straightforward, with the hose laid out flat, allowing for easy flipping and pulling. The triple layer load effectively organizes and protects the hose while enabling efficient deployment. In contrast, the circular load can create complications when trying to quickly access and use the hose, which is why it is not a standard choice for preconnected attack lines.
