What color indicates a nonfunctioning hydrant?

Explanation:
Color coding hydrants helps firefighters know at a glance whether a hydrant is usable and what kind of water supply to expect. When a hydrant is marked or painted black, it signals that it is out of service or nonfunctional. This quick cue prevents wasting time trying to draw water from a hydrant that isn’t working and prompts responders to find an alternative water source or arrange for repair. Keep in mind that color codes can vary by city or country, so local standards matter. In other schemes, different colors might indicate flow capacity or other statuses, but in this context black specifically denotes nonfunctioning.
