Objectives • Identify the chemical hazards • List potential locations • Explain what PPE may be required • Describe the effects of chronic exposure
PCBs means polychorinated biphenyls. Figure 1 Container of wiring being processed
209individual chlorinated compounds make up the chemical PCB. Figure 2 Vessel in slip awaiting for dismantling
It comes in an oily liquid or solids that range from colorless to yellows. Figure 3 PCB wiring in roll off box
There is no associated taste or smell. Figure 4 PCB shredder operation
The PCB makes good insulators. Figure 5 Close up view of electrical wiring
In 1977, the U.S. outlawed the manufacturing of PCB. Figure 6 Roll off box container for electrical wiring
Lubricants in transformers. Figure 7 Storage area for PCB’s and mercury
Electrical wiring that runs throughout the ship and inside wiring of equipment. Figure 8 Electrical wiring in the engine room
Capacitors Figure 9 Electrical components in drum
Prior to 1977 fluorescent lighting may contained PCB. Figure 10 Recycled lighting in container
Vacuum pump fluids Figure 11 pumps in the engine room
Limits for air contaminants is 0.5 mg/m3 Figure 12 Engine room near the generator
Protective clothing to reduce skin contact. Figure 13 Worker in protective clothing on board vessel
Respirators when potential for airborne contaminates exist. Figure 14 Full faced respirator
Face shield or goggles to prevent contact with face or eyes. Figure 15 Face shield and secondary eye protection
Chemical resistant gloves and boots should be worn if exposure to liquid has been identified. Figure 16 Rubber gloves sealed to suit
Ensure adequate ventilation when working in a confined space. Figure 17 Ventilation unit on containment
Studies conclude that liver damage occurs with PCB exposure. Figure 18 Containment exercise
Impairs reproductive systems. Figure 19 Crowd of people in park
Some studies concluded that exposure increases risk of cancer. Figure 20 Roll off container of water collected on board
Exposure to skin may causes rashes Figure 21 Exercise in containment barriers
Behavior problems associated with motor skills and short-term memory. Figure 22 Breaking down containment room after exercise
