  2. CONFINED SPACE &TRENCH RESCUE AWARENESS

  3. CONFINED SPACE

  4. OBJECTIVES: As presented in this class, identify: • Ten hidden hazards associated with confined space rescue • The requirements imposed by the Illinois department of labor for persons involved in rescue operations

  5. How the national fire protection association, Illinois department of labor, occupational safety and health administration, ANSI and NIOSH all interface • The methods of victim and rescuer protection • Required entry and retrieval systems • Air quality monitoring and control systems

  6. Isolation techniques • The initial command operations at the scene of a confined space rescue • The initial tasks of the first-in company at the scene of a confined space rescue

  7. A Confined Space means a space that: • Is large enough and so configured that an employee can bodily enter and perform assigned work; and • Has limited or restricted means of entry; and • Is not designed for continuous employee occupancy

  8. Permit Required Confined Space (PRCS) Is 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

  9. 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 • Contains any other recognized serious safety or health hazard

  10. Non-Permit Confined Space Is 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

  11. Types Of Confined Spaces • Sewers • Silos • Vats • Ventilation and exhaust ducts • Boilers • Degreasers • Pipelines • Underground utility vaults • Tunnels • Railroad tank cars

  12. Example of local confined space locations

  13. Silos -Industrial or Agricultural

  14. Manholes- Sanitary or Storm

  15. Rail CarsLiquid Tank or Dry Bulk

  16. Industrial Storage Tanks

  17. Reasons for entering confined spaces • Cleaning • Inspections • Maintenance • Training • Rescue

  18. Confined Space Requirements are detailed in OSHA Standards29 CFR 1910.146Permit-Required Confined Spaces for General Industry - Final Rule& 29 CFR 1910.147Control of Hazardous Energy(Lock-out/Tag-out)

  19. Definitionsto aid in understanding the OSHA regulations...

  20. Qualified (Competent) 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 This person shall be capable of specifying necessary control and/or protective action to insure worker safety.

  21. Attendant A trained individual, stationed outside the Confined Space area who monitors authorized entrants working in Permit-Required Confined Spaces

  22. Authorized Entrant A trained individual who is authorized to enter a Permit-Required Confined Space area to perform work

  23. 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

  24. For every entry into a PRCS you will need: At least one attendant At least one entrant An entry supervisor (although the entry supervisor does not need to remain on site)

  25. 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:

  26. Flammable gas, vapor, or mist in excess of 10% of its Lower Flammable Limits (LFL) • Airborne combustible dust at a concentration that meets or exceeds its (LFL) • Oxygen concentration below 19.5% or above 23.5%

  27. Concentration of any substance published in Subpart G, Occupational Health and Environmental Control, or Subpart Z, Toxic and Hazardous Substances, in access of its dose or Permissible Exposure Limits (PEL) Note: A concentration of any substance that is capable of causing death, incapacitation or impairment of ability to self-rescue, injury, or acute illness due to health effects is not covered by this provision

  28. Any other atmospheric condition that is Immediately Dangerous to Life and Health (IDLH)

  29. 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

  30. Immediately Dangerous to Life and Health (IDLH) Any condition that: • Poses an immediate or delayed threat to life • Would cause irreversible adverse health effects • Would interfere with an individuals ability to escape unaided from a permit space

  31. Oxygen Deficient Atmosphere An atmosphere containing less than 19.5% percent by oxygen by volume

  32. Oxygen Enriched Atmospheres An atmosphere containing more than 23.5% oxygen by volume

  33. 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

  34. 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 • Double block and bleed • Lock-out, tag-out, or tryout of all sources of energy • Blocking or disconnecting of all linkages

  35. Retrieval System The equipment including a retrieval line, class III harness, wristlets, if appropriate, and lifting device) used for non-entry rescue of workers from a permit-required confined space

  36. 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 safely

  37. 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 Considered to have occurred as soon as any part of the entrants body breaks the plane of an opening into the space

  38. Entry Permit The written or printed document provided by the Authority Having Jurisdiction (AHJ) to allow and control entry to a permit space

  39. A permit is simply a checklist • Not issued by the Federal, State or Local government • Minimum contents set by OSHA • Many formats

  40. 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. Each permit contains the information specified in paragraph (f), ("ENTRY PERMIT") of the standard

  41. Prohibited Condition Any condition in a permit space that is not allowed by the permit during the period when entry is authorized

  42. Requirements General

  43. The Employer will decide if the workplace contains Permit Required Confined Spaces (PRCS)

  44. If workplace contains Permit Required Confined Spaces, the Employer must inform employees of their existence, location and dangers

  45. If the Employer decides employees will enter permit spaces, the Employer shall develop and implement a written entry program

  46. The Employer may use alternate entry procedures provided certain conditions and requirements are met

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

  48. 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

  49. 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
