Why are warning labels and orange color important on EV components?

• A. They automatically protect workers from all hazards.
• B. They indicate high‑voltage hazards, instruct avoidance of contact, and remind technicians to follow safe procedures; they do not replace proper isolation.
• C. They are legal documentation.
• D. They indicate the color of the battery.

Answer: (B)

Warning labels and the orange color on EV components serve as immediate, visible reminders of high-voltage risk and the need to follow safe work practices. The orange hue helps technicians quickly identify parts that carry dangerous energy, reducing the chance of accidental contact during maintenance. Labels provide specific hazard information and instructions to avoid contact, require appropriate PPE, and remind workers to follow established safe procedures. But they are part of a safety system, not a replacement for actually isolating the energy source; proper de-energization and verification steps are still essential to ensure a component is truly safe to work on. These cues work together to improve hazard awareness and consistency, while not eliminating the risk on their own.
