A fire attack mode tactic used to reduce temperatures inside a building prior to entry is called what?

• A. Nozzles
• B. Ventilation
• C. Slicers
• D. Dicers

Answer: (C)

Pre-entry cooling depends on ventilation—opening the structure to release heat, smoke, and gases so interior conditions improve before crews advance. The slicing roof ventilation approach is a controlled method of venting that creates openings in the roof to rapidly exhaust hot gases. By allowing heat to escape efficiently, interior temperatures drop and air flow improves, making it safer and more effective for the attack team to enter with a charged line. Water from a nozzle can cool surfaces, but it doesn’t establish the ventilation path itself. Other terms aren’t standard names for this pre-entry cooling tactic, whereas the slicing method directly accomplishes the temperature reduction through planned ventilation.
