Report a Critical Infrastructure Incident
If a significant security incident is detected while in progress, the facility should immediately call local law enforcement and emergency responders via 9-1-1. Similarly, if the event has concluded but an immediate response is still necessary, the facility should immediately call 9-1-1. Once the incident has concluded and the facility has addressed any resulting emergency, the facility should use a nonemergency number to contact local first responders and other federal, state, and local law enforcement entities, as applicable.
