What should safety personnel immediately do upon discovering a fire?

The appropriate action for safety personnel upon discovering a fire is to activate the fire alarm and initiate emergency procedures. This response is critical because it alerts everyone in the building to the emergency situation, allowing them to evacuate safely. It also informs the local fire department or emergency services that assistance is needed.

By activating the fire alarm, safety personnel ensure that the building's evacuation protocols are put into motion, guiding occupants to exit routes and assembly points. Additionally, initiating emergency procedures enables trained staff to coordinate the response, ensuring that everyone responds appropriately and efficiently under pressure.

While attempting to extinguish the fire or calling for help may seem like plausible actions, they shouldn't be prioritized over ensuring that the alarm is activated. Evacuating the premises is indeed necessary but should typically occur following the activation of the alarm and the initiation of emergency procedures to ensure a systematic evacuation process.
