What constitutes a high‑voltage safety zone in a vehicle?

• A. The area around high‑voltage components (orange cables, service disconnect, battery pack) that requires PPE and de‑energization; unauthorized personnel should stay out.
• B. The entire parking lot.
• C. Only the battery pack.
• D. The interior passenger area.

Answer: (A)

High-voltage safety zones are the defined areas immediately around energized vehicle components where the energy must be controlled and access restricted. The best choice identifies the zone around high‑voltage parts—the orange cables, the service disconnect, and the battery pack—because these are the components that can still hold or re‑energize hazardous energy. In this zone, the system should be de‑energized and appropriate PPE used to protect against electric shock or arc flash. Keeping unauthorized people out helps prevent contact with live parts and reduces the risk of injury. This zone is not the entire parking lot, not just the battery pack alone, and not the interior passenger area, since those options don’t specify the boundary around the HV components or the need for de‑energization and protective measures.
