  1. Ship Yard Safety Brief MLCA (kse)

  2. Confined Space

  3. What is a confined space?

  4. OSHA defines a confined space as: • 1. Any space which by design has limited opening for entry and exit ( one way in and out ). • 2. Unfavorable ventilation which could contain or produce dangerous air contaminants. • 3. Not intended for continuous occupancy.

  5. Tanks • Manholes • Voids

  6. The some major hazards associated with a confined space.

  7. Oxygen deficient atmosphere contain less than 19.5% oxygen.

  8. Toxic Vapors and gases which exceed their PEL (Permissible Exposure Limit).

  9. Flammable or Combustible atmosphere in which vapors or gases are equal to or greater than 10% LEL (Lower Explosive limit).

  10. Has the potential to engulf a person.

  11. Other Hazards • Rust a potential oxygen deficiencies. • Organic materials such as fruits,vegetables deteriorate into hydrogen sulfide gas. • Standing seawater will deplete oxygen and deteriorate into hydrogen sulfide and methane gases.

  12. Gas Free Engineer • Gas Free Engineers may only certify compartments gas free for Coast Guard military personnel only. • Commercial contractors that requires entry into a confined space, shall provide a certified marine chemist (NFPA approve).

  13. Immediately dangerous to life or health (IDLH) • Flammable vapors at a concentration of 10% or greater of the LEL. • Oxygen content less than 16.5% • Presence of toxicants above the NIOSH approved IDHL limits.

  14. Underway Emergency An oxygen breathing apparatus (OBA) may be used for entry into a potentially IDLH if the following conditions are met... NSTM 074 -18.8

  15. Underway when required by an emergency • Approved by the CO.



  18. Fire watches When open flame or heat producing work (welding, cutting or brazing) is conducted, the work-site must be inspected by the Gas Free Engineering ( GFE ) regardless of location.

  19. Fire watch personnel must be protected against the same hazards as the operator.

  20. All fire watch personnel must be qualified in Basic Damage Control PQS.

  21. Fire watches viewing arc welding or cutting are exposed to UV or intense visible light causing flash burns or eye damage

  22. Use tinted glasses # 6 shade

  23. Fire watch personnel must be outfitted with a metal- fume respirator. If ventilation in the vicinity can not be depended upon for good fume removal, then respirator are necessary.

  24. Welding or Burning will require HEPA ( high efficiency particulate air filter )

  25. Bring to the scene a fire extinguisher ( CO2 or Water Bottle) that is compatible with the surrounding combustibles.


  27. Eye Hazards • Puncture

  28. Radiation

  29. Impact

  30. Particles/Dust

  31. Protective Eyewear


  33. Selection • First determine the type of hazard present. • Select the appropriate respirators. • Select the Cartridges / Pre-filter.

  34. Types of Hazards Dust: Solid particles are broken down. Irritates nose, airways, throat. Mist: Tiny droplets of liquid. Irritates nose airways, throat.. Fumes: When Plastic or metal is heated, contains particles of plastic or metal. Collect in your favorite organs. Vapor: Substance that evaporates from a liquid or solid. Goes directly to lungs and blood. Gas: A substance which becomes airborne at room temperature. Goes directly to lungs then bloodstream.

  35. TYPES OF RESPIRATORS Positive Pressure Air Purifying Respirator • Dust Mask DO NOT USE

  36. Selection • Grinding or Sanding will require a particulate cartridges. • Spraying paint will require a organic vapor cartridges with a paint spray pre-filter.

  37. HEPA (high efficiency particulate air filter ) • When in doubt, check the MSDS sheet.

  38. Inspect respirator prior to use. • Must be clean and sanitary • No cuts or nicks, will prevent a good seal. • Must be soft and pliable. • Check valves.

  39. The Fit Test • Cover cartridges with the palms and inhale. Facepiece should collapse. • Cover exhalation valve with hands, mask should inflate. • Adjust straps as needed. Don’t use respirator if you can’t pass fit test!

  40. Maintenance • Clean Respirators by disassembling / washing in warm water and mild detergent. • store mask and cartridges in ziplock bags. • Use a locker to store respirators and cartridges.

  41. Hearing Conservation

  42. Sound Levels • 85-90 dba: Shop tools • 90-100 dba: Shop tools,small engines. • 100-130 dba: deck-growler. • 140 dba + Explosions, Painful acoustic trauma.

  43. 85-100 dba - Single hearing protection. • 104+ dba - Double hearing protection.

  44. Disposable plugs • Yellow foams offer good protection, cheap, comfortable can be supplemented with muffs. • Bands keep clean, replace seals when no longer adequate.

  45. Ear Muffs • Best protection, ensure pads are around the outside of muffs, remain pliable and clean.

  46. Electrical and Tag-out Safety

  47. Civilian contractors and shipyard workers follow 29 CFR 1915.132 Portable electric tools as their safety standard.

  48. Contractor electrical equipment hazard should be brought to the safety officer or ship-sup.

  49. Contractors and shipyard worker must follow the ship’s tag-out procedures . • Only qualified ship’s force personnel shall position equipment and install tags, check and shall remove all tags.

  50. Tag shall be attached such they are apparent to anyone who may attempt to operate the equipment.
