  1. Module 5: Operations & Hot Work 5.3 Hot Work, Permits, and Inspections Susan Harwood Grant Number SH-17820-08-60-F-23

  2. This material was produced under grant number SH-17820-08-60-F-23 from the Occupational Safety and Health Administration, U.S. Department of Labor. It does not necessarily reflect the views or polices of the U.S. Department of Labor, nor does mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government.

  3. Identify the steps to prepare space for hot work • Review the procedures for testing the atmosphere • Describe types of hot work operations • List personnel protective equipment needed

  4. Cutting, brazing • Source of ignition when flammable materials exist • Becomes hot work processes • Hot work permit

  5. Hot work is one of the most essential operations in dismantling a vessel. Figure 1 Fire watch standing by during hot work in cargo tank

  6. Figure 2 Torch cutting through the hull

  7. Includes welding, cutting, burning, abrasive blasting, and other heat-producing operations. Figure 3 Cutting torch operations

  8. Dismantling of vessels generally occurs in confined or enclosed spaces. Figure 4 Hot work inside cargo hold

  9. Many accidents happen during hot work operations due to falls, accidents, burns, explosions, fires, etc. Figure 5 Cutter working along walkway inside cargo compartment

  10. Firstthere needs to be a plan on the type of hot work that is to take. Figure 6 Cutting with torches inside yard

  11. Adjacent spaces need to be surveyed to verify that the hot work operations will not cause hazardous conditions. Figure 7 Cargo vessel awaiting to be inspected

  12. Figure 8 Working in bilge area near shaft alley

  13. Figure 9 Piping removed from the hull

  14. Figure 10 Long view of a compartment being removed

  15. Figure 11 Compartment with two hot work operations

  16. Figure 12 Cut outs for ventilation

  17. Remember the fire watch is available and has the appropriate fire suppression equipment. Figure 13 Fire watch on bank monitoring hot work on vessel

  18. Figure 14 Inspecting the area and spaces

  19. Figure 15 Calibrating equipment

  20. Areas to be inspected are hollow structures such as mast and pipes for flammable vapors or liquids. Figure 16 View of the double bottom tank and piping exposed

  21. Figure 17 View of the engine room compartment and upper crew decks

  22. The visual and testing will maintain the Marine Chemist certificate and prevent the chemist from re-evaluating the compartment. Figure 18 Cutting down along the side of the vessel

  23. Outside the space signage must be posted “Safe for Hot Work” or “Safe for Workers”. Figure 19 Posted signage

  24. Figure 20 Supervisor monitoring the hot work operations

  25. The supervisor will provide the scope of the operations to the workers prior to hot work beginning. Figure 21 Surveying the operations

  26. Figure 22 Hot work on the stern near the rudder system

  27. Review the Marine Chemist Certificate and test log and request re-testing if there are questions concerning the atmosphere. Figure 23 Hot work in the exposed engine room

  28. Check the surfaces for residue or materials that may affect hot work. Figure 24 Inside view of the cargo tanks that were removed

  29. Figure 25 Fumes raising from the hot work

  30. Inspect the cutting equipment such as torch, hoses, gauges, and connections for damage or leaking. Figure 26 Cutting torch

  31. Figure 27 Worker in protective gear

  32. Account for other personnel that are in the affected area. Figure 28 Accountability for personnel at the gangway

  40. Figure 36 Workers with respirators and face shields

  41. Figure 37 Inside view of cargo fuel tanks

  42. Figure 38 Welding face shield

  43. Welding hood or face shield should be worn when there is a risk of sparks or slag coming in contact with the face. Figure 39 Face shield with protective coating shield

  44. Protective outer clothing must be made out of material that is fire resistant. Figure 40 Snapping in fall protection
