This module addresses the critical workplace and chemical hazards associated with polychlorinated biphenyls (PCBs) in shipbreaking environments. It aims to identify potential chemical hazards, outline common locations where exposure may occur, and recommend appropriate personal protective equipment (PPE) to safeguard workers. Additionally, it discusses the long-term health effects of PCB exposure, including liver damage, reproductive system impairment, and increased cancer risk. Understanding these risks is vital to maintaining worker safety in shipbreaking operations.

  3. Objectives • Identify the chemical hazards • List potential locations • Explain what PPE may be required • Describe the effects of chronic exposure

  4. PCBs means polychorinated biphenyls. Figure 1 Container of wiring being processed

  5. 209individual chlorinated compounds make up the chemical PCB. Figure 2 Vessel in slip awaiting for dismantling

  6. It comes in an oily liquid or solids that range from colorless to yellows. Figure 3 PCB wiring in roll off box

  7. There is no associated taste or smell. Figure 4 PCB shredder operation

  8. The PCB makes good insulators. Figure 5 Close up view of electrical wiring

  9. In 1977, the U.S. outlawed the manufacturing of PCB. Figure 6 Roll off box container for electrical wiring

  10. Lubricants in transformers. Figure 7 Storage area for PCB’s and mercury

  11. Electrical wiring that runs throughout the ship and inside wiring of equipment. Figure 8 Electrical wiring in the engine room

  12. Capacitors Figure 9 Electrical components in drum

  13. Prior to 1977 fluorescent lighting may contained PCB. Figure 10 Recycled lighting in container

  14. Vacuum pump fluids Figure 11 pumps in the engine room

  15. Limits for air contaminants is 0.5 mg/m3 Figure 12 Engine room near the generator

  16. Protective clothing to reduce skin contact. Figure 13 Worker in protective clothing on board vessel

  17. Respirators when potential for airborne contaminates exist. Figure 14 Full faced respirator

  18. Face shield or goggles to prevent contact with face or eyes. Figure 15 Face shield and secondary eye protection

  19. Chemical resistant gloves and boots should be worn if exposure to liquid has been identified. Figure 16 Rubber gloves sealed to suit

  20. Ensure adequate ventilation when working in a confined space. Figure 17 Ventilation unit on containment

  21. Studies conclude that liver damage occurs with PCB exposure. Figure 18 Containment exercise

  22. Impairs reproductive systems. Figure 19 Crowd of people in park

  23. Some studies concluded that exposure increases risk of cancer. Figure 20 Roll off container of water collected on board

  24. Exposure to skin may causes rashes Figure 21 Exercise in containment barriers

  25. Behavior problems associated with motor skills and short-term memory. Figure 22 Breaking down containment room after exercise
