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
– Work on power circuits
– Procedures during repairs or maintenance
– 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

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

9. 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

10. Some Types of Energy Electrical Mechanical Chemical Thermal Hydraulic
Pneumatic

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

12. Potential Energy (Gravity)

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

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

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

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

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

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

19. Use of Locks

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

22. 7. Prepare for Startup Put all guards back Remove tools
Inform others of startup
Restore system connections
Remove locks & tags
