  1. Lockout/Tagout(The Control of Hazardous Energy)

  2. Why Lockout/Tagout?

  3. When is LO/TO Required? When someone will be servicing or repairing machinery or equipment AND The unexpected machinery start-up or release of stored energy could cause injury

  4. Who Needs Training? Authorized employees – People who lock or tag out machines or equipment to perform servicing Affected employees – People who use machines or equipment on which servicing is performed under lockout/tagout Other employees – People who work in the area of locked out machinery or equipment

  5. What is Hazardous Energy? Electricity – live or stored Moving machinery parts Stored mechanical movement in machinery

  6. What is Hazardous Energy? Stored heat (steam lines or hot liquids) Chemicals in pipelines under pressure or force of gravity Any other active or stored energy sources that could harm a worker

  7. Hazardous Energy Source Examples Live electrical lines Electrical capacitors Lasers Engines that move machinery parts Hydraulic lifts Pneumatic (air pressure) lines Springs

  8. Service and Maintenance • Adjusting • Lubricating • Set-up (Preparing for normal function) • Service/Repair These activities often require a worker to place all or part of his body into the machine’s hazard zone.

  9. What is a Lockout Device? • A device that: • Prevents a machine from being started up or turned on • Prevents a machinery part from moving • Prevents electrical energizing • Blocks a pipeline, steam line or air line

  10. Electrical Lockout Devices Locked out circuit breaker Locked out electrical panel

  11. Electrical Lockout Devices Electric Cord Lockout Wall Switch Lockout

  12. Fluid & Gas Lockout Devices

  13. Pipe Lockout Examples

  14. Physical Blocks Truck bed lockout Punch press blocks

  15. Group Lockout Devices Used when more than one person doing maintenance or repair on same machine or equipment Machinery or equipment can not be started up until all locks are removed Each person places and removes their own lock

  16. Many On-Line Resources

  17. Is This Adequate?

  18. What About This?

  19. …And This?

  20. Lockout – 7 Progressive Steps Isolate Energy Shut Down Equipment 3 Notify Employees 2 1 6 Release Stored Energy Attach Lockout Device 5 Verify Lockout 4 Service & Maintenance 7

  21. What is Tagout? Tags are warning devices only • They do not provide the same level of protection as lockout devices • They can only be used alone if there is no other way to “positively control hazardous energy”

  22. Tagout • A tag is a visual warning (not a physical restraint) • Use as a supplement to a lockout device for best results
