  1. CONFINED SPACE 8 HOUR CONFINED SPACE / TRENCH AWARENESS

  2. CONFINED SPACE • Types of Confined Spaces • Sewers • Silos • Vats • Ventilation and Exhaust ducts • Boilers

  3. CONFINED SPACE • Types of Confined Spaces • Pipelines • Underground Utility vaults • Tunnels • Railroad & Roadway tank cars

  4. CONFINED SPACE • Reasons for entering confined spaces • Cleaning • Inspections • Maintenance • *** Training *** • *** RESCUE ***

  5. CONFINED SPACE • Definitions • Qualified person • A person designated by the Employer in writing, as capable (by education and/or specialized training) of anticipating, recognizing and evaluating employee exposure to hazardous substances or other unsafe conditions in a Confined Space

  6. CONFINED SPACE • Definitions • Qualified person • This person shall be capable of specifying necessary control and/or protective action to insure worker safety

  7. CONFINED SPACE • Definitions • Attendant = A trained individual, stationed outside the Confined Space area who monitors authorized entrants working in Permit - Required Confined Spaces

  8. CONFINED SPACE • Definitions • Authorized Entrant = A trained individual who is authorized to enter a Permit - Required Confined Space area to perform work

  9. CONFINED SPACE • Definitions • Entry Supervisor = A trained individual who verifies that all requirements for Permit - Required Confined Space entry have been met, authorizing and overseeing entry operations, and for terminating entries

  10. CONFINED SPACE • Definitions • Hazardous Atmosphere = An atmosphere that may expose employees to the risk of death, incapacitation, impairment of ability to self - rescue (that is, escape unaided from a permit space), injury or acute illness from one or more of the following:

  11. CONFINED SPACE • Definitions • Hazardous Atmosphere = Flammable gas, vapor, or mist in excess of 10% of its Lower Flammable / Explosive Limits (LFL / LEL)

  12. CONFINED SPACE • Definitions • Hazardous Atmosphere = Airborne combustible dust at a concentration that meets or exceeds its LEL / LFL

  13. CONFINED SPACE • Definitions • Hazardous Atmosphere = Oxygen concentration below 19.5% or above 23.5%

  14. CONFINED SPACE • Definitions • Hazardous Atmosphere = Concentration of any substance published in Subpart G, Occupational Health & Environmental Control, or Subpart Z, Toxic and Hazardous Substances, in excess of its dose or Permissible Exposure Limits (PEL)

  15. CONFINED SPACE • Definitions • Hazardous Atmosphere = Any other atmospheric condition that is Immediately Dangerous to Life & Health (IDLH)

  16. CONFINED SPACE • Definitions • Hazardous Atmosphere = Immediately Dangerous to Life & Health (IDLH) - any condition that • Poses an immediate or delayed threat to life • Would cause irreversible adverse health effects

  17. CONFINED SPACE • Definitions • Hazardous Atmosphere = Immediately Dangerous to Life & Health (IDLH) - any condition that • Would interfere with an individuals ability to escape unaided from a permit space

  18. CONFINED SPACE • Definitions • Engulfment - The surrounding and effective capture of a person by a liquid or finely divided (flowable) solid substance that can be aspirated to cause death by filling or plugging the respiratory system, or that can exert enough force on the body to cause death by strangulation, constriction, or crushing

  19. CONFINED SPACE • Definitions • Oxygen Deficient Atmosphere - an atmosphere containing less than 19.5% oxygen by volume

  20. CONFINED SPACE • Definitions • Oxygen Enriched Atmospheres - an atmosphere containing more than 23.5% oxygen by volume

  21. CONFINED SPACE • Definitions • Permit Required Confined Space (PRCS) - a confined space that has one or more of the following characteristics • contains or has a potential to contain a hazardous atmosphere • contains a material that has a potential for engulfing an entrant

  22. CONFINED SPACE • Definitions • Permit Required Confined Space (PRCS) - a confined space that has one or more of the following characteristics • has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes and tapers to a smaller cross section

  23. CONFINED SPACE • Definitions • Permit Required Confined Space (PRCS) - a confined space that has one or more of the following characteristics • contains any other recognized serious safety or health hazard

  24. CONFINED SPACE • Definitions • Non-Permit Confined Space - A space that does not contain or, with respect to atmospheric hazards, have the potential to contain any hazard capable of causing death or serious physical harm

  25. CONFINED SPACE • Definitions • Inerting - displacement of the atmosphere in a permit space by a noncombustible gas (such as nitrogen) to such an extent that the resulting atmosphere is noncombustible

  26. CONFINED SPACE • Definitions • Isolation - The process by which a permit required confined space is removed from service and completely protected against the release of energy and/or material into the confined space by such means as • Blanking and bleeding • Removing sections of lines, pipes or ducts

  27. CONFINED SPACE • Definitions • Isolation - The process by which a permit required confined space is removed from service and completely protected against the release of energy and/or material into the confined space by such means as • Double block and bleed • Lockout, tagout, or tryout of all sources of energy • Blocking or disconnecting of all linkages

  28. CONFINED SPACE • Definitions • Retrieval system - the equipment including a retrieval line, class III harness, wristlets, if appropriate, and lifting device used for on-entry rescue of workers from a permit-required confined space.

  29. CONFINED SPACE • Definitions • Acceptable Entry Conditions - the condition that must exist in a confined space to allow entry and ensure that employees involved with a permit-required confined space entry can work within the confined space

  30. CONFINED SPACE • Definitions • Entry - • The action by which a person passes through an opening into a permit required confined space, and includes ensuing work activities in that space

  31. CONFINED SPACE • Definitions • Entry Permit - • The written or printed document provided by the Authority Having Jurisdiction (AHJ) to allow and control entry to a permit space

  32. CONFINED SPACE • Definitions • Entry Permit - • Content of each permit is based on the AHJ’s identification and evaluation of each hazard of that permit space, or class of spaces, and all procedures the AHJ’s requires for protecting entrants from those hazards during entry

  33. CONFINED SPACE • Definitions • Entry Permit - • Each permit contains the information specified in paragraph (f), (“ENTRY PERMIT”), of the standard

  34. CONFINED SPACE • Definitions • Prohibited Condition - any condition in a permit space that is not allowed by the permit during the period when entry is authorized

  35. REQUIREMENTS • General • The employer will decide if the workplace contains Permit Required Confined Spaces (PRCS)

  36. REQUIREMENTS • General • If workplace contains PRCS, the employer must inform employees of their existence, location and dangers

  37. REQUIREMENTS • General • If the employer decides employees will enter permit spaces, the employer shall develop and implement a written entry program

  38. REQUIREMENTS • General • The employer may use alternate entry procedures provided certain conditions and requirements are met

  39. REQUIREMENTS • General • When there are changes in use or configuration of a non-permit confined space that might increase the hazards to entrants, the Employer shall, if necessary, reclassify as a permit space

  40. REQUIREMENTS • General • If there are no actual or potential atmospheric hazards and if all hazards within the space are eliminated without entry, space may be reclassified for as long as the non-atmospheric hazards remain eliminated

  41. REQUIREMENTS • General • If entry into a confined space is required to eliminate hazards, it shall be according to regulations and the confined space may be reclassified for as long as the hazards remain eliminated.

  42. REQUIREMENTS • General • The entry supervisor shall certify in writing that all hazards in PRCS have been eliminated and make this document available to each entrant

  43. REQUIREMENTS • General • If hazards arise in Alternate Entry Permit Space or Non-permitted Space, employees shall exit the confined space and the entry supervisor shall determine whether to reclassify the confined space

  44. REQUIREMENTS • General • When the employer arranges for contractor to perform PRCS entry work, the Employer shall • Inform contractor of the employer’s PRCS entry program

  45. REQUIREMENTS • General • When the employer arranges for contractor to perform PRCS entry work, the Employer shall • Appraise contractor of particular PRCS hazards, precautions and procedures implemented for protection of employees in or near the Permitted Space

  46. REQUIREMENTS • General • When the employer arranges for contractor to perform PRCS entry work, the Employer shall • Coordinate entry operations with contractor when both will be working in or near Permitted Spaces and debrief contractor after entries

  47. REQUIREMENTS • General • When the employer arranges for contractor to perform PRCS entry work, the Employer shall • Contractors shall comply with the Employers PRCS Entry Program during combined employee entries and coordinate multiple entry operations

  48. REQUIREMENTS • Alternate Entry Procedures • The AHJ may use alternate entry procedures as specified in OSHA standard 1910.146 under certain conditions listed below • The Entry Supervisor demonstrates that only hazards posed by permit space is actual or potential hazardous atmosphere

  49. REQUIREMENTS • Alternate Entry Procedures • The AHJ may use alternate entry procedures as specified in OSHA standard 1910.146 under certain conditions listed below • The Entry Supervisor demonstrates that continuous forced air ventilation alone is sufficient to maintain a safe permit space

  50. REQUIREMENTS • Alternate Entry Procedures • The AHJ may use alternate entry procedures as specified in OSHA standard 1910.146 under certain conditions listed below • The employer develops monitoring and inspection data that supports above demonstrations
