What is the purpose of establishing safe work boundaries during EV maintenance?

• A. To define where work is permitted and ensure only trained personnel operate near HV areas.
• B. To determine which snacks are allowed during breaks.
• C. To allocate parking spaces for technicians.
• D. To decide which brand of tools to use.

Answer: (A)

Establishing safe work boundaries around EV systems is about controlling access to high-voltage areas and energy storage zones. By defining where work is permitted, we ensure only qualified technicians with the right training and authorization enter those zones, reducing the risk of electric shock, arc flash, or accidental contact with live components. These boundaries support proper isolation and lockout/tagout procedures, the use of appropriate PPE, and clear signs and barriers so everyone on site understands where special precautions are needed. In short, they minimize exposure to hazardous energy by keeping unqualified people out and ensuring work is performed in a controlled, planned way.
