What is the typical sequence for a basic fire attack using a 1 3/4 inch handline in a residential fire?

• A. Enter first, throw water into flames, retreat.
• B. Size-up, locate the fire, deploy the line, advance to the seat, apply water, check for extension, and continue suppression.
• C. Call for help, package the hose, wait for a backup crew.
• D. Attach ladder, ventilate, flood with foam.

Answer: (B)

A basic interior fire attack follows a logical, safety-focused sequence: size-up the scene to understand conditions and risks, locate the fire to know where to direct water, deploy a charged handline, advance to the fire seat, apply water to cool and knock down the flames, check for extension behind walls or in hidden spaces, and continue suppression until the fire is controlled. This order matters because early size-up informs entry strategy and safety, knowing the fire location ensures the stream is aimed where it’s most effective, and advancing with a charged line to the seat of the fire allows rapid cooling and extinguishment at the source. Skipping steps or reversing them—such as rushing water without locating the fire, delaying entry for backup, or introducing ventilation or foam in a way that isn’t part of a basic attack—can reduce effectiveness and increase risk.
