  3. Objectives • Explain what are chemical hazards we are dealing with • Identify potential locations • List what PPE may be required to work in • Define chronic exposure effects

  4. Objectives • Explain the hazards what are we dealing with • Cite potential locations • List personal protective equipment required • Describe chronic affects

  5. What Are We Dealing With?

  6. Mercury is a naturally occurring metal in the environment. Figure 1 Mercury recovered and being recycled

  7. It is considered a heavy metaland stands to reason why it is so toxic if exposed. Figure 2 Recycled bag filter of mercury

  8. Mercury’s nickname is “Quicksilver” Figure 3 Bulb Eater filter recovered

  9. Odorless, metallic, shiny, silver-white liquid and can be difficult to handle if spilled. Figure 4 Light bulbs being recycled

  10. In 1996 Federal regulations phased out the use of mercury in batteries. Figure 5 Batteries being recycled

  11. When heated, turns into a vapor and is considered colorless and odorless Figure 6 Cutting on pads

  12. Exposure is through skin absorption and inhalation Figure 7 Electronic equipment that has mercury components

  13. Galleys and freezers are on every type of vessel. Figure 8 Gauges in galley areas

  14. Oilers or commonly known as supply ships contain large quantities of mercury in equipment. Figure 9 Recycled bulb eater system to recover mercury

  15. There are certain types of fluorescent lighting that contain mercury. Figure 10 Fluorescent light recovered from the vessel for recycling

  16. Mercury is the mechanics of the basic operations of the thermometer.. Figure 11 Old thermometer and barometer

  17. Barometers are located in the bridge of the ship to forecast weather changes. Figure 12 Ship’s barometer

  18. Hospitals, sickbays, doctors compartments may have wall mounted sphygmomanometers for blood pressure or left in drawers. Figure 13 Blood pressure checks prior to entry

  19. Mercury-Containing rechargeable batteries. Figure 14 Battery packs rechargeable

  20. Prior to the 1990’s mercury was used in antifouling paint on ships hull. Figure 15 Antifouling paint exposed hull of vessels

  21. Mercury switches were used prior to the 1970’s. Figure 16 Electronic equipment with potential switches

  22. PPE Requirements

  23. Employees should have initial evaluations conducted prior for background monitoring. Figure 17 TSTC conducting medical surveillance prior to entry

  24. Wearing protective clothing that is turned in at the end of each shift. Figure 18 Mercury containing products waiting to be recycled

  25. Protective clothing includes, but is not limited to coveralls, smocks, and aprons Figure 19 Lab testing with aprons

  26. When hotwork is being conducted the use of hair covers or hats are recommended. Figure 20 Display respirator and hard hat

  27. Do not use compressed airto remove mercury from protective clothing. Donot shake PPE. Figure 21 Tyvek suit outer clothing

  28. Street clothes should not be worn whenever airborne mercury concentrations exceed the PEL. Figure 21 PETE personnel discussing shipbreaking at Marine Metals

  29. Instruct personnel on the use of respirators and limitations that respirators. Figure 22 Respirator usage during hotwork on pad

  30. The use of contact lens not recommended. Figure 23 Working in the area of engine room

  31. Mercury is toxic to living organisms and has a wide range of disorders. Figure 24 Workers dismantling valves

  32. Kidney damage and digestive disorders may result . Figure 25 Worker on the main deck in protective clothing and eye wear

  33. Mercury poisoning can occur with only a few dropabsorbing into the skin. Figure 26 TSTC testing chemicals

  34. Muscle weakness & skin rashes. Figure 27 Amfels drill conducting medvac exercise

  35. Memory loss to mood swings. Figure 28 Amfels exercise firefighters surveying workers down

  36. May impair walking or writing coordination. Figure 29 Cutter and worker in background on break

  37. “Pins and needle” sensation in the hands and feet. Figure 30 Cutting section on double bottom hull

  38. Troubled sleeping, irritability, memory loss Figure 31 Overall view of the slip and winch area

  39. Treatment with medicine may reduce mercury in the blood. Urine also rids mercury from the body. Figure 32 Medical chest on site of workplace
