In the described system, which vehicle is used to supply compressed air for filling SCBA cylinders?

• A. Ladder truck
• B. Air truck
• C. Ambulance
• D. Tanker

Answer: (B)

Providing a mobile, high‑pressure air source for SCBA fills is the job of an air truck. These vehicles carry a compressor, high‑pressure air storage, and a cascade filling system to pressurize and fill SCBA cylinders on scene or at a station. Ladder trucks, ambulances, and tankers aren’t equipped for this purpose in the same way—ladder trucks are for access and rescue, ambulances for medical transport, and tankers for water or fuel. So the vehicle used to supply compressed air for filling SCBA cylinders is the air truck.
