Telescopic bars are used to place which desmoking equipment?

• A. Tube axial fan
• B. RAM fan
• C. Fog nozzle
• D. Positive pressure fan

Answer: (A)

Establishing an effective desmoking airflow by mounting the right equipment at openings is what this item tests. Telescopic bars are used to position gear precisely where you need it—across a doorway or hatch—so you can set up the airflow path without exposing the team to heat or smoke or needing to squeeze into tight spaces. The tube axial fan is the best match here because it’s a compact, high-volume fan that can be mounted on those extendable bars and aimed to pull smoke out of the space through the opening. This setup creates a clear exhaust route quickly and allows you to adjust the fan’s position for optimal airflow.

Fog nozzles are for applying water fog to suppress or cool fires, not for creating an exhaust path. RAM fans and positive pressure fans serve different purposes in desmoking and compartment pressurization, but they aren’t as commonly mounted on telescopic bars to establish the direct exhaust path through an opening as a tube axial fan.
