In what order should rescue efforts be extended according to fire service protocols?

Rescue efforts in fire service protocols prioritize the safety of individuals based on the level of threat they face. The correct sequence, starting with the severely threatened, ensures that those at the greatest immediate risk of harm are addressed first. Individuals in severely threatened situations are often in life-threatening circumstances, making their rescue a top priority.

Following this, the focus shifts to exposed areas. This includes people and locations that, while not currently in immediate danger, might be impacted by the fire or are at risk of becoming severely threatened if the situation escalates.

Lastly, addressing the largest numbers involves reaching out to the greatest quantity of people who may be safe but could be affected by the fire if conditions change. This order ensures that the most vulnerable are prioritized for rescue, maximizing the effectiveness and safety of the operation.

Other options may shift the focus to different categories or prioritize larger groups before assessing the most immediate threats, which does not align with the fundamental principle of prioritizing life safety based on imminent danger.
