All of the following are procedures for activating the Hospital Incident Command System (HICS) EXCEPT:

The correct choice indicates that referring to the Job Action Sheet (JAS) for response duties is not a procedure for activating the Hospital Incident Command System (HICS). While the Job Action Sheet provides important information regarding individual roles and responsibilities during an emergency response, it does not play a direct role in the activation of HICS itself.

The activation of HICS primarily involves immediate actions that are more logistical and procedural in nature, such as contacting local emergency services to coordinate external support, gathering necessary personnel to ensure that all roles are filled in the command structure, and activating hospital emergency systems which include essential protocols and resources required in an emergency situation. These steps are critical to setting up an effective response infrastructure to manage the incident effectively.

In contrast, the Job Action Sheet serves as a guide for what actions should be taken once the system is already activated, rather than being involved in the activation process itself. This distinction clarifies why referring to the JAS does not qualify as a direct procedure for initiating HICS.
