Which step comes last in the desmoking sequence?

• A. Prep path
• B. Rig blower
• C. Establish & maintain
• D. Verify air quality

Answer: (C)

This question tests the order of steps in a desmoking sequence. After you’ve opened the path for smoke to move out, the next essential action is to set up and drive the ventilation so air flows correctly through the space. The final action is to establish and maintain that ventilation system, keeping the airflow steady and the conditions stable for the duration of the desmoking effort. Once you have the path prepared and the blower in place, locking in the ventilation parameters and continuously maintaining them ensures the space remains safe as smoke clearance proceeds. Verifying air quality is important, but it’s an ongoing check that supports the established ventilation rather than the last step of setting everything up.
