What should be done if individual sprinkler heads cannot be plugged?

Stopping the flow at the sprinkler control valve is the most appropriate action when individual sprinkler heads cannot be plugged. This step is crucial for preventing further water damage and managing the situation effectively. By closing the control valve, you can halt the water supply to the system, which minimizes the ongoing impact of the uncontrolled water flow while maintaining protection for other areas of the building that are not yet affected.

This is essential in fire situations where water from sprinklers can cause significant collateral damage, particularly in non-fire-affected areas. Additionally, halting water flow allows for a more controlled approach to assessing and managing the incident, including enabling personnel to focus on the fire itself without the complication of uncontrolled water discharge.

Redirecting the flow to a water source is not a viable option, as it would not resolve the issue of uncontrolled water flow. Evacuating the building may be warranted in certain situations, but it does not address managing the sprinkler system directly. Contacting the local fire department is important for emergency response, yet tackling the immediate water flow issue at the source is crucial for effectively controlling the situation during the initial response.
