What should be the first step of a firefighter when arriving at a fire scene?

The first step for a firefighter when arriving at a fire scene is to conduct a scene size-up. This crucial process involves evaluating the situation to understand the scope of the incident, determine the resources needed, and identify any potential hazards. During a size-up, firefighters assess the fire's location, size, and behavior, as well as the building's structure, layout, and possible victims. This assessment allows for informed decision-making regarding firefighting tactics and the safety of personnel.

By conducting a thorough scene size-up, firefighters can prioritize their actions, such as whether to initiate a water supply connection or check for nearby hazards. Gathering equipment from the truck may also be necessary, but it should follow the assessment to ensure that the right tools are brought based on the situation. Ultimately, the size-up is vital for ensuring both effective firefighting operations and the safety of all responders at the scene.
