What should firefighters do first upon arrival at a fire incident?

Upon arriving at a fire incident, it is crucial for firefighters to establish command and assess the situation as the first step. This initial action allows the incident commander to evaluate the scene and gain an understanding of the fire's size, location, and potential hazards. Establishing command helps ensure that all personnel on the scene are informed about the incident and can operate cohesively.

Assessing the situation involves gathering critical information, such as the status of the fire, any reports of trapped occupants, and the condition of the building. This comprehensive assessment enables the incident commander to formulate a strategic plan to tackle the fire while prioritizing the safety of both the firefighters and any potential victims.

Properly established command also facilitates effective communication among the responding units, ensuring that resources are allocated efficiently. This systematic approach not only increases the likelihood of successfully managing the incident but also helps protect lives and minimize property damage. The other options involve actions that could compromise safety or be premature without a proper assessment of the situation.
