What action should Safety Officer Simmons take after a post-incident member illness is reported?

The correct action for Safety Officer Simmons to take after a post-incident member illness is reported is to inform the Incident Commander (IC) that a responder sought medical care. This is critical because the IC needs to be made aware of any situation that could affect operational safety and decision-making. The health and safety of responders is a top priority during any incident, and timely communication of illnesses or injuries ensures that the IC can adjust strategies, allocate resources, and take necessary precautions to protect the team and ensure an effective response.

Keeping the IC informed about all aspects related to responder well-being is essential for maintaining situational awareness and operational integrity. Additionally, it can help in assessing potential risks associated with the incident and enhances the overall safety protocols.

The other options, while they may seem relevant in different contexts, do not directly address the immediate need to communicate health-related incidents involving responders. Thus, promptly informing the IC about a responder's need for medical care is the most appropriate and necessary action in this situation.
