Which capability must a Level 1 technician demonstrate?

• A. Mechanical wrenching speed
• B. High-voltage electrical safety awareness
• C. Battery swapping
• D. Painting

Answer: (B)

High-voltage electrical safety awareness is essential because electric vehicles use high-energy powertrains that can cause severe shock, burns, or arc flash if proper precautions aren’t followed. A Level 1 technician must recognize HV hazards, read warning labels, and follow safety protocols to isolate or de-energize systems when required, use the appropriate PPE, and maintain safe working distances. This knowledge helps prevent injuries while working around EV components and ensures they can operate safely in environments where high-voltage systems are present, even if they aren’t performing advanced HV maintenance themselves. The other activities—quick mechanical wrenching, battery swapping, or painting—do not focus on recognizing and mitigating high-voltage hazards and thus aren’t the capabilities emphasized at this level.
