What does the orange color coding and labeling communicate specifically to technicians?

• A. It marks equipment for disposal.
• B. It indicates low-voltage equipment.
• C. It shows equipment is ready for charging.
• D. It flags high-voltage systems and requires strict isolation, PPE, and careful safe handling.

Answer: (D)

Orange color coding signals a high-voltage hazard and the presence of dangerous electrical energy. It tells technicians to treat the equipment with strict safety controls: isolate and de-energize before work, verify zero energy, and use the appropriate PPE and safe-handling procedures. This risk isn’t just about being energized; it also implies the potential for arc flash, so protective gear such as arc-rated clothing, face shields, and insulated gloves may be required, along with proper lockout/tagout and careful work practices. The label is a clear directive that special precautions are needed to prevent electric shock or arc injuries.

This isn’t about disposal (which uses different markings), nor does it indicate low-voltage equipment or charging readiness—the orange cue is specifically about high-voltage risk and the need for careful isolation and PPE.
