What is the labeling requirement for PCB-containing equipment?

• A. Paint equipment with color green.
• B. Remove all markings.
• C. Clearly mark PCB-containing equipment.
• D. Place a sticker.

Answer: (C)

Equipment that contains PCBs must be clearly marked. This labeling makes the presence of PCBs obvious to anyone handling, maintaining, or disposing of the equipment, so they can follow the proper safety and regulatory procedures. PCBs are hazardous and regulated, so clear identification helps prevent accidental exposure, improper handling, or improper disposal. A durable, legible mark (often stating “PCB-containing” and including any required dates or concentrations) ensures the info remains available throughout the equipment’s life.

Painted green, removing markings, or simply placing a sticker do not provide the standardized, persistent identification needed for safe and compliant handling.
