During a fire operation, which action best describes desmoking in the buffer zone?

• A. Active desmoking
• B. Ventilation
• C. Passive cooling
• D. Smoke purging

Answer: (A)

Desmoking the buffer zone is about actively removing smoke from that space to keep it tenable for operations. Doing this actively means using mechanical means—fans, blowers, and properly positioned ducting or exhaust paths—to pull the smoke out of the buffer zone and vent it away from occupied areas. This direct, controlled removal improves visibility and reduces inhalation risk for crew working nearby and for teams entering adjacent compartments. Ventilation is related but broader and doesn’t guarantee targeted smoke removal; passive cooling focuses on lowering heat, not smoke; smoke purging implies expelling smoke but isn’t as precise a method for keeping the buffer zone clear. So, actively desmoking the buffer zone is the best description because it specifically and effectively removes smoke through mechanical means.
