Which step must come first in the procedure for cutting out air brakes on a freight car?

• A. Bleed all air from the reservoirs
• B. Request 3-step protection
• C. Move the cut-out cock to the closed position
• D. Release 3-step protection

Answer: (B)

In the procedure for cutting out air brakes on a freight car, the first step should always be to request 3-step protection. This is essential as it ensures the safety of personnel involved in the process. The 3-step protection system involves measures that need to be taken to safeguard workers by ensuring that the train cannot move unexpectedly while air brakes are being cut out. By requesting 3-step protection first, the crew can implement safety protocols to avoid accidents, ensuring that they are following standard operating procedures. Once this safety measure is in place, the remaining steps can be safely performed, which include bleeding air from the reservoirs, moving the cut-out cock, and releasing the protection as needed. This sequence prioritizes the safety of everyone involved in the operation.
