Definition & Operational Usage
Underfire refers to a critical operational state in which firefighters are engaged in direct firefighting efforts while simultaneously facing imminent threats from flames, toxic smoke, or potential structural failure. Not to be confused with routine firefighting activities, underfire situations demand heightened situational awareness and adherence to safety protocols such as the Incident Command System (ICS) and the use of Personal Alert Safety Systems (PASS). These scenarios require swift decision-making and effective coordination among team members to mitigate risks and ensure operational effectiveness.
