  1. Lockout - Tagout Control Of Hazardous Energy

  2. You Will Learn… • Purpose of lockout-tagout • Requirements for LOTO • Types of hazardous energy • Procedures for LOTO

  3. Regulations • 56.12016 – Work on electrically powered equipment • 56.12017 – Work on power circuits • 56.14105 – Procedures during repairs or maintenance • 56.14211 – Blocking equipment in a raised position

  4. This Happens Often Employee accidentally leaned on the start switch & turned on the machine himself...

  5. Lockout • Prevents release of hazardous energy • Lock placed on appropriate energy isolating device that is in the off or closed position

  6. Tagout • Identifies problem • Identifies lockout date • Identifies person • Used by itself only when cannot be locked out

  7. Lockout/Tagout Use • Repaired • Serviced • Lubricated • Cleaned • Un-jammed • Adjusted • Maintained • Guard removed

  8. Causes Of Injury • Failure to stop equipment • Failure to disconnect from power source • Failure to bleed energy • Accidental restarting of equipment • Failure to clear work areas before restarting

  9. Some Types of Energy • Electrical • Mechanical • Chemical • Thermal • Hydraulic • Pneumatic

  10. Mechanical Energy • Kinetic - machinery in motion • Gears • Belts • Potential - stored energy • Weights (gravity) & springs • Pistons under pressure • Hydraulic controls

  11. Potential Energy (Gravity)

  12. LOTO Procedure • Prepare for shutdown • Shutdown equipment • Isolate all energy sources • Apply locks & tags • Verify isolation • Control stored energy • Prepare for Startup

  13. 1. Prepare • Plan your work & locate instructions • Understand equipment hazards • Notify others of shutdown

  14. 2. Shutdown • Normal shutdown procedure • Turn all switches to OFF • Shut all control valves

  15. 3. Isolate Sources • Disable all energy sources • Shut valves • Open breakers & disconnects

  16. 4. Apply Locks • Valves • Breaker & electrical disconnects • Block or disconnect all lines

  17. Plug locks Ball valve Gate valve Hasp Electrical Hydraulic Pneumatic Lockout Devices

  18. Use of Locks • Use only locks issued to you – lock all energy isolation gear • Never use another workers lock or tag • Tell supervisor if you need more LOTO equipment

  19. 5. Verification • Prior to servicing or maintenance, authorized employee must verify that equipment is isolated by turning it on

  20. 6. Control Stored Energy • Block or release springs or other tension • Block elevated parts • Stop rotating flywheels • Relieve system pressure • Drain fluids • Vent gases

  21. 7. Prepare for Startup • Put all guards back • Remove tools • Inform others of startup • Restore system connections • Remove locks & tags • Restore equipment to normal • Conduct normal startup

  22. Who Can Remove Locks & Tags? • Only the employee who placed the lock and/or tag • A supervisor, after obtaining permission from the worker who placed the tag

  23. Question • Equipment already has a lock and tag on it.  Do I have to place my own locks & tags? YES.  everyone working on equipment must place their own locks and tags

  24. Contractors • All contractor employees must follow plant LOTO procedures!

  25. Why Workers Don’t Lockout • Performed or witnessed someone doing work without lockout • Disconnecting device too far away or not convenient • Worker alone and felt no need to lockout • Not wanting to stop production

  26. Dump Bed Locking

  27. Adequate Blocking?

  28. How did he get this blocked?

  29. In order to properly block or secure any piece of mobile equipment, you must block or pin all articulation joints. Failure to properly secure articulation could result in vehicle movement when it is blocked in the raised position.

  30. Sometimes the Instructions Are Handy

  31. What is This Pin For?

  32. Is This Machine Blocked Adequately?

  33. How is This For Blocking?

  34. Works for Me but What’s The Wire For?

  35. Locked and Tagged, But Tag Could Be Improved!

  36. Adequate Blocking?

  37. Adequate Blocking?

  38. Adequate Blocking?

  39. Adequate Blocking?

  40. Adequate Blocking?

  41. Adequate Blocking?

  42. Adequate Blocking?

  43. Adequate Blocking?

  44. Adequate Blocking?

  45. Adequate Blocking?

  46. Think First • Jaw crusher turned off… • No locks in sight… • Yellow hat is a man inside...

  47. LOTO Protects You • Use proper lockout - tagout procedures • Please be careful when working on equipment
