When performing maintenance on a vehicle, the primary safety goals are to prevent accidental startup, isolate hazardous energy sources, and prevent any unexpected movement of the vehicle. This aligns with standard Workplace Safety protocols.

Evaluate each option

• Barricade doors: This is not a standard safety precaution for vehicle maintenance.
• Remove key from ignition: Essential to prevent accidental startup of the engine.
• Use LOTO devices: Lockout/Tagout (LOTO) devices are critical to isolate electrical or mechanical energy sources during service, following standard Lockout Tagout Steps.
• Turn off ignition: Necessary first step before any work begins to shut down the engine.
• Remove fuses: A key method of electrical energy isolation to prevent circuits from being energized.
• Set brakes: Crucial to prevent the vehicle from rolling or moving unexpectedly.
• Block wheels: Wheel chocks/blocks must be used in conjunction with brakes to physically secure the vehicle.
• Lock doors: Locking the vehicle doors is not a standard safety precaution for performing maintenance.
