What is the first step in calling an Incident Command System (ICS)?

The correct choice is to begin with the phrase "Flash, Flash, Flash," which is a common communication protocol used to alert incident responders that an emergency situation is unfolding. This phrase acts as a clear and immediate signal to ensure that all personnel are aware that a serious incident is occurring and that they should be prepared to act and follow the ICS protocols.

Using this alert system enhances the effectiveness of the communication, ensuring that information about the incident is transmitted quickly and effectively. This prompt action is essential because it sets the stage for the subsequent steps in the ICS process and ensures that relevant teams are aware and can mobilize as needed.

The other options, while relevant to incident reporting and management, follow after the initial alert. Naming the incident, reporting location, and describing the situation are crucial steps in the overall command and control process; however, they happen after the initial alert to get the attention of all responders involved.
