What must the D/E Candidate do if the hydrant is over 50' away during Drill #7?

In Drill #7, if the hydrant is over 50 feet away, using a 5" straight lay is the appropriate action to ensure efficient water supply during operations. The 5" hose is designed to maximize flow rates while minimizing friction loss, making it ideal for long-distance lays. This technique ensures that adequate water pressure can be maintained as it travels to the apparatus, facilitating effective fire suppression.

A 3" hose lay, while functional, may not provide the same volume of water as a 5" lay and could lead to inadequate supply under heavy demands. Connecting to a pump truck may not be necessary if a direct supply is available from the hydrant, which is typically the preferred method. Asking for assistance from another unit could delay operations and is generally avoided unless absolutely required, especially if the resources available from the hydrant can adequately meet the demands of the situation.

Thus, the 5" straight lay is the optimal choice due to its efficiency in maintaining water flow over the longer distance, essential for effective firefighting operations.
