What could be a potential consequence of using a large diameter hose as an attack hose?

Using a large diameter hose as an attack hose can lead to difficulty in maneuverability for several reasons. Larger hoses are generally heavier and bulkier than those with smaller diameters, making them more challenging to handle, especially in cramped or complex environments often encountered in firefighting scenarios. The added weight and size can restrict a firefighter's ability to quickly position the hose and move it around obstacles, ultimately affecting operational efficiency and response time.

While the other consequences might seem plausible in different contexts, they are not the primary concern when it comes to large diameter hoses being used as attack hoses. For example, flow rates are generally expected to increase with larger hoses due to their capacity to transport larger volumes of water, while pressure may remain consistent depending on the pump system's configuration. Although excess wear could occur if the hose is improperly managed, it is not as immediate a consequence in terms of operational capability as maneuverability issues would be in the field.
