Incident Termination

Once a PV incident is under control, verify that all components have been fully electrically isolated. Work with CPS Energy personnel to permanently secure the system and prevent it from feeding voltage into the occupancy or the power grid.

After the system is rendered safe, provide command personnel with an update on the situation and the status of the PV system. A full face-to-face briefing should take place before command is transferred.

A fire service crew should remain on the scene until the system is properly secured and an isolation area is established.

If a battery storage system is involved, expect a long-term event and the potential for battery re-ignition. Once thermal propagation has stopped and batteries are no longer off-gassing, the system should be turned over to the system installer or other skilled maintenance personnel.
