Count the Cost of Not Locking Out...
Metal-Nonmetal Electrical Lockout Injuries over 10 Years:
30 Fatalities
6 Permanent disabilities
257 Lost time injuries
45 Restricted day injuries

4. A miner was fatally injured in this log roller when the motor was started while he worked inside. Electrical power had not been disconnected. This tragedy could have been avoided had the victim locked out the power to the machine.

5. A miner was electrocuted when his hand came in contact with 480 volts.
He did not lock, tag & try, nor was he wearing electrically rated gloves.

6. had not been disconnected and locked out.
Two men were injured when this distribution panel shorted out during a repair. Electrical energy
had not been disconnected and locked out.

7. Energy Sources to Control
Electricity
Machinery
Pressure lines & vessels
Sliding / falling material
Miscellaneous

8. Hazardous energy must be controlled when:
Removing guards, covers, shields
Performing maintenance
Inspecting equipment internally
Troubleshooting
Unchoking

9. Workers At-Risk
The vast majority of electrical accidents occurs while work is being performed on energized circuits during maintenance or troubleshooting. Even the most qualified personnel sometimes seem to disregard the dangers and risks involved.

10. Reasons Given for Not Locking Out
Waste of time - lost production time
Supervisor praise for fast repair
Only takes a ‘minute’ for repair on “energized” equipment
Fatigue: too far or too much trouble to turn off power
Finish undesirable task quickly
Finish before going home

11. For myself For my family For my co-worker For my profession
Why to Lock Out
For myself
For my family
For my co-worker
For my profession
For my company

12. Federal Regulations

13. Distribution Boxes 30 CFR 56/57.12006
Distribution boxes shall be provided with a disconnecting device for each branch circuit. Such disconnecting devices shall be equipped or designed in such a manner that it can be determined by visual observation when such a device is open and that the circuit is deenergized, and the distribution box shall be labeled to show which circuit each device controls.

14. A “distribution box” is an enclosed portable apparatus through which an electric circuit is carried to one or more cables from a single incoming feed line.
Each cable circuit must be connected through an individual overcurrent protective device.

15. The distribution box should be observable to indicate when the device is open and the circuit is deenergized.
Where plugs are used to provide power, the plugs and cables need to be positively identified prior to any work on the equipment.
Positive identification is essential to prevent an accident from occurring. The following photo displays why this is so important.

16. Many distribution boxes and power centers
have a window at each individual circuit where
circuit deenergization can be visually determined

17. Work on power circuits 30 CFR 56/57.12017
Power circuits shall be deenergized before work is done on such circuits unless hot-line tools are used. Suitable warning signs shall be posted by the individuals who are to do the work. Switches shall be locked out or other measures taken which shall prevent the power circuits from being energized without the knowledge of the individuals working on them.

18. Work on electrically powered equipment 30 CFR 56/57.12016
Electrically powered equipment shall be deenergized before mechanical work is done on such equipment. Power switches shall be locked out or other measures taken which shall prevent the equipment from being energized without the knowledge of the individuals working on it.

19. 30 CFR 56/ , continued
Suitable warning notices shall be posted at the power switch and signed by the individuals who are to do the work.
Such locks or preventive devices shall be removed only by the persons who installed them or by authorized personnel.

20. Electrically Powered Equip.
De-energize before mechanical work
Lock out power switches
Post warning notice
ID tag on lock is OK
Lock must be installed and removed only by person to whom it is issued

21. BRANCH CIRCUIT DISCONNECTING DEVISES
30 CFR
Disconnecting switches that can be opened safely under load shall be provided underground at all branch circuits extending from primary power circuits near shafts, adits, levels and boreholes.

22. Lockout Hardware

23. Locks

24. Multi-lock adapters

25. Tags To quickly identify the worker who is using the lock

26. Lockout Procedures

27. Prepare Pre-plan Coordinate w/ others Erect barricades / warning signs
Operators, co-workers, contractors
Erect barricades / warning signs

28. Shutdown Use stop switch
If multiple switches, use one closest to equipment
Do not use disconnect switch to stop: arcing could cause injury / damage

29. Isolate Disconnect from all energy sources
Insulate self from electrical power
non-conductive platform, gloves, dry clothes
Stand to side of disconnect device, not in front
Avert eyes & face

30. Left Hand Disconnect Eyes Averted, Insulating Platform for Wet Conditions

31. Right Hand MCC Disconnect Stand Aside, Eyes Averted Insulated Gloves for Higher Voltage

32. Lockout Affix lock or appropriate device to disconnect switch
Do not lock out start / stop switch
Latch shackle & remove key
Personal locks: keep key
System locks: key placed in system lock box

33. Field Disconnect Lockout
Right
Wrong

34. Main Disconnect Lockout
This shows how a main disconnect should be locked and tagged.

35. Motor Starter Lockout
This shows how a motor starter should be locked and tagged.

36. Single Pole Circuit Breaker Lockout
This shows how a single pole circuit breaker should be locked and tagged.

37. Double Pole Circuit Breaker Lockout

This shows how a cable plug should be locked and tagged.

40. Latch the Lock’s Shackle !!
But don’t lock through
another person’s lock !

41. Independent Power Sources
Lock out all independent, related parts of unit or system being repaired
Valves: lock or chain
Tag & sign
Block parts that may drop, creep, drift or turn

42. System Lockout For related equipment groups
Provide marked locks & keys in lockable box in central location

46. Tryout Verify & Test Push “Start” switch Equipment should not start
If equipment starts, shut down & verify proper equipment is locked out
If starts & proper equipment is locked out, warn, post guard & notify immediately

47. Release Stored Energy
Block non-electrical devices that could release stored energy
Release spring, hydraulic or pneumatic pressures

48. Machinery Guards Keep them in place until: Machine is stopped
Power supply de-energized

49. Start Up Authority After Repairs
Reinstall guards first
Do not start without authority & training
Communicate with co-workers and contractors
Be certain no one is in position to be injured

50. Lock Removal
Personal lock to be removed only by person to whom it is issued
