If Class Alpha cannot enter due to extreme heat but can operate from the doorway, what type of attack are they performing?

• A. Indirect attack
• B. Fog attack
• C. Direct attack from compartment access
• D. Mechanical isolation

Answer: (C)

When you can’t enter a space because of extreme heat, but you can work at the doorway, you’re performing a direct attack from compartment access. This means you apply a water/agent stream directly into the fire through the doorway, aiming at the flames and fuel source as if you were inside, but without stepping into the hot compartment. The nozzle team seeks to directly cool and suppress the fire at its source from the threshold. This isn’t indirect attack, which would involve cooling or manipulating the fire from a distance away from the flame and not applying the agent directly to the fire. It isn’t a fog attack, which uses a wide, fog-pattern to blanket the area for cooling or smoke control rather than direct flame contact. And it isn’t mechanical isolation, which is about shutting off fuel or ventilation routes rather than attacking the fire itself.
