Which true statement reflects a function of first responders?

First responders are primarily responsible for providing initial command and control at the scene of an incident. This critical function involves assessing the situation, ensuring the safety of victims and bystanders, and coordinating immediate response efforts. By establishing authority and directing emergency operations, first responders set the groundwork for subsequent actions by additional support agencies and units. This role is essential to stabilize the situation and implement necessary assistance swiftly.

The other choices encompass functions that may occur after the initial response phase. For instance, managing resources and expanding command typically involve a broader range of personnel and agencies as the incident response evolves beyond initial actions. Conducting post-incident evaluations usually occurs after the immediate crisis has been addressed, focusing on analyzing the efficacy of the response and identifying areas for improvement in future incidents.
