Which of the following is NOT one of the three primary responsibilities of an incident commander?

The role of an incident commander is pivotal in emergency management, focusing primarily on three key responsibilities: life safety, incident stabilization, and property conservation.

Life safety encompasses ensuring the protection of all individuals involved, including both responders and the public. Incident stabilization refers to controlling the situation to prevent further escalation, such as containing a fire or halting hazardous material spills. Property conservation involves safeguarding property from further damage during emergencies, ensuring that any measures taken do not exacerbate the incident.

Public relations, although important in the broader context of incident management, does not fall under the primary responsibilities of an incident commander. While managing communications and public perceptions is essential, it is typically handled by a different role, such as a public information officer. Thus, public relations is not classified among the core duties aimed at addressing the immediate challenges faced during an incident, which reinforces why it is the correct choice in this context.
