Imagine the following scenario: Firefighters are dispatched to a local residence where fire is showing from the second-story front window. Arriving on the scene, the firefighters begin to evaluate potential water sources, spot a fire hydrant on the street, and head toward it to establish a water supply. As they reach the hydrant, they realize it’s not operational—it’s completely consumed by a tree and vegetation! They’ll be lucky if they can open just one of the outlets, especially after noting a red tag displaying “out of service” in faded letters.
