Which statement is true regarding the use of 2 1/2" hose in supply line scenarios according to the SOG?

In the context of standard operating guidelines (SOG) for firefighting, the statement that 2 1/2" hose should never be used as a supply line accurately reflects the limitations and intended uses of different hose sizes. Supply lines are typically larger diameter hoses, often 4" or larger, which allow for the rapid movement of significant water volumes to support firefighting operations.

The 2 1/2" hose is generally not appropriate for supply line purposes due to its reduced capacity compared to larger hoses. Using it as a supply line could restrict water flow and hinder the effectiveness of the water supply needed during firefighting scenarios.

While 2 1/2" hoses serve important roles in other capacities, such as attack lines for engaging with fires or in specific tactical operations, their function is limited when it comes to supplying water from a hydrant to the apparatus. This distinction is crucial for firefighters to understand, as it impacts the efficiency and safety of emergency responses.
