  1. PERMIT-REQUIRED CONFINED SPACE 29 CFR 1910.146

  2. Terminal Learning Objective (TLO) • Action: Identify the scope and application of 29 CFR 1910.146 Permit-Required Confined Space • Condition: Given classroom instruction • Standard: In accordance with • (IAW 29) CFR 1910.146

  3. Enabling Learning Objectives (ELO’s) • 1. Identify a Permit-Required Confined Space (PRCS) • 2. Identify employer and contractor responsibilities • 3. Identify permit-required confined space program requirements • Identify the different types of confined space permits

  4. Enabling Learning Objectives (ELO’s) • 5. Identify personnel requirements for permit space entries • 6. Identify the procedures for a permit space entry • 7. Identify confined space hazards and hazard control methods • Identify atmospheric testing procedures • Identify ventilation procedures • Operate safely in a confined space

  5. 29 CFR 1910.146 Permit-Required Confined Space Scope and Application: • Contains requirements for safe practices and procedures to protect employees in general industry from the hazards of entry into Permit- Required Confined Spaces (PRCS)

  6. A Confined Space is defined as: • Large enough and so configured • that an employee can bodily enter to perform assigned work and • Limited or restricted in its means • of entry and exit and • Not designed for continuous • employee occupancy

  7. Permit-Required Confined Space is a Confined Space that: • Contains or has the potential to • contain a hazardous atmosphere • Oxygen Deficiency, Toxic Gases, Flammable Gases • Contains a material that has the • potential for engulfing the entrant • Solid or Liquid

  8. Has an internal configuration such • that an entrant could be trapped or • asphyxiated by inwardly converging • walls or by floors which slope down • and taper to a small cross-section • Silo, Hopper, Shafts • Contains any other recognized serious • safety or health hazard • Biological Hazards: Snakes, Spiders, or Machinery

  9. PERMIT-REQUIRED CONFINED SPACE AREAS TANKS VESSELS REACTORS MANHOLES VATS BOILERS SILOS HOPPERS BINS VAULTS TUNNELS PIPES PITS TANK TRUCKS TANK CARS

  10. EMPLOYERS SHALL Identify - Locate Permit-Required Confined Spaces Inform employees by posting signs, training or other effective methods Prevent entry by unauthorized persons Develop a written plan - If employees are to enter

  11. CHECK ON LEARNING

  14. HOST EMPLOYER Arranges for contractor to perform work involving confined space entry

  15. HOST EMPLOYER WILL INFORM THE CONTRACTOR OF Permit-Required Confined Spaces in the workplace Permit-Required entry procedures Confined space hazards Precautions and procedures

  16. HOST EMPLOYER SHALL Coordinate entry operation with the contractor Debrief contractor Host employer remains responsible for contractor if contractor is untrained or has no Confined Space Entry/Rescue capability

  17. CONTRACTOR SHALL Obtain information on confined spaces from host Coordinate entry operations with host Inform host of entry procedures contractor will follow Debrief Host
