Which step comes second in the desmoking sequence?

• A. Prep path
• B. Rig blower
• C. Establish & maintain
• D. Check for hazards

Answer: (B)

In desmoking, you move from safety assessment to creating controlled airflow. The immediate priority is to identify and mitigate any hazards in the space so you don’t spread heat, smoke, or fuel vapors during ventilation. Once you’ve confirmed the area is safe to operate in, the next action is to rig the blower. Setting up the ventilation equipment right after hazards are addressed ensures you can start moving air without introducing new dangers or spreading smoke into adjacent areas. With the blower in place, you then establish and maintain a clear air path—opening doors, vents, and hatches as needed to guide the smoke toward the exhaust and keep clean spaces protected. Prep the path and other steps come after you’ve secured a safe, directed airflow.
