Which tactic can push hot gases and steam down near the floor and cause serious steam burns to firefighters?

• A. Indirect Attack
• B. Direct Attack
• C. Ventilation
• D. Rescue

Answer: (A)

Pushing hot gases and steam down toward the lower part of the room happens with indirect attack. By directing a wide fog pattern high or away from the flames to cool the ceiling and upper layer, the hot, buoyant gases lose their tendency to rise. As the upper layer cools, those gases can descend into the lower zone, bringing steam and high heat with them. This creates a real risk of steam burns to firefighters working near the floor. Direct attack focuses water onto the flames themselves, not the gas layer, while ventilation and rescue serve other objectives—removing gases or rescuing occupants, respectively.
