When an inoperative hydrant is found, what should be done with the hydrant bag?

Placing the hydrant bag over the inoperative hydrant is the correct action because it serves to visibly mark the hydrant as out of service. This visual indicator ensures that firefighters and other emergency personnel are aware that the hydrant cannot be used for water supply during an incident. It helps prevent wasted time and potential risk during emergency operations, where a functioning hydrant would otherwise be expected. Additionally, the presence of the bag can prompt further follow-up actions, such as reporting the inoperative condition for repair, ensuring that it is addressed in a timely manner.

Other potential actions, like leaving the bag at the station or notifying dispatch using it, would not provide the immediate visual warning necessary for on-site responders. Additionally, simply marking it as inoperative provides clarity to all departments involved without relying on dispatch communication, which may lead to delays.
