26. 26 Employer Responsibilities under 29 CFR 1910.146: 1.Evaluate workplace to identify permit- required spaces. 2.Make location and dangers of spaces known to employees. DANGER! PERMIT-REQUIRED CONFINED SPACE DO NOT ENTER

27. 27 Employer Responsibilities: 3.If employees will not enter a permit- required space, take measures to ensure it cannot be entered 4.If employees will enter permit-required spaces, employer must establish entry permit program Exception: when optional provisions apply

28. 28 Requirements For Permit Space Program Must meet thirteen basic requirements GOAL: Insure that 1. Hazards of space are identified, 2. Safety precautions are taken before entry, and 3. Timely rescue is available if needed

29. 29 THE ENTRY PERMIT Documents compliance with the standard and authorizes entry Must be posted at entry location Identifies personnel involved in the entry operation Identifies hazards, safety precautions, and acceptable entry conditions Provides contact info in case of emergency

30. 30 PERSONNEL ROLES IN PERMIT SPACE OPERATIONS Entrant - works inside the space Attendant - remains at point of entry to monitor safety of entrant Supervisor - verifies safety precautions and signs permit to authorize entry Rescuer - on call or standby in case of emergency

31. 31 RESCUE AND EMERGENCY SERVICES (paragraph k) The employer must: Evaluate and select rescue team or service able to perform rescue in a timely and effective manner Appendix F provides non-mandatory evaluation criteria

36. 36 Optional Provisions For Confined Space Entry Alternate Procedures Reclassification to Non-Permit Status

37. 37 Alternate Procedures: Allowable Conditions Only atmospheric hazards involved Can be abated by forced air ventilation Supporting monitoring and inspection data developed Initial data gathered under permit- required entry conditions Supporting data available to workers

38. 38 Alternate Procedures: Requirements for Use Conditions making removal of cover unsafe eliminated before cover is removed Quality of ventilation air assured Atmosphere tested prior to entry Periodic monitoring during entry

39. 39 Alternate Procedures: Allowable Atmospheric Conditions Oxygen Concentration: 19.5% - 23.5% Flammability: 5% of the LEL Toxicity: 50% of the PEL

40. 40 Requirements for Reclassification to NON-Permit Status No actual or potential atmospheric hazard Any other hazard eliminated prior to entry Employer documents basis through certification Employees will exit if hazards arise, and space will be reevaluated.
