How many sections of 2 1/2" hose should a Minneapolis engine have on the working load?

The correct answer is based on the standard operating procedures of the Minneapolis Fire Department, which specifies that an engine should carry a specific amount of fire supply hose to ensure adequate water flow during firefighting operations. In this case, the requirement is that an engine must have 18 sections of 2 1/2" hose on the working load.

Carrying 18 sections of this size hose provides firefighters with the flexibility and volume needed to handle various fire suppression scenarios, particularly those involving structural fires where high flow rates are often necessary. This standard helps ensure that there is sufficient hose length to reach potential fire locations while maintaining the necessary water pressure for effective firefighting. Having a standardized amount, like 18 sections, also facilitates training and operational readiness as firefighters are familiarized with the same rigging across various situations and engines.

The other choices do not meet the established guidelines, as having too few sections may compromise operational effectiveness, while carrying more than necessary can lead to difficulties in transport and deployment at fire scenes.
