What should be the first action upon discovering a fire in a building?

The first action upon discovering a fire in a building should be to evacuate the building. Safety is the top priority in any fire situation. The immediate evacuation of all occupants minimizes the risk of injury or fatalities. It is crucial to ensure that everyone is accounted for and safely outside before any further actions are taken.

While calling for backup, attempting to extinguish the fire, or performing a primary search are important steps in firefighting procedures, they should only be considered after ensuring that all individuals in the building have been evacuated. The focus should initially be on protecting lives, as time can be critical in fire situations, and attempts to combat the fire can place individuals at unnecessary risk if they are not sure everyone is safe. Therefore, a prompt evacuation not only facilitates a safer environment for responders but also allows for a more organized and effective response to the emergency.
