What is the correct sequence for advancing an interior hose line in a structure fire?

• A. Enter and blast water indiscriminately
• B. Ensure water is available; stretch line to the fire area; advance with the nozzle in the correct pattern; apply water to the seat of the fire; maintain a back-up line.
• C. Move quickly inside without water
• D. Start by cooling the exterior walls

Answer: (B)

Securing a reliable water supply before entering is essential, because an interior attack without water is ineffective and dangerous. Once water is available, stretch the line to the fire area so the nozzle can reach the seat of the fire while keeping the hose manageable and ready to move with you. Then advance with the nozzle in the correct pattern, maintaining a controlled flow and an appropriate spray to keep the nozzle man capable of adjusting as conditions change, rather than pushing blindly through heat and smoke. When you reach the fire, apply water directly to the seat of the fire to knock down the flames and reduce heat buildup, which helps protect you and any occupants. Keep a back-up line ready to deploy for protection or if the primary line loses pressure or extinguishment becomes more challenging.
