LOTO Is an EHS Tool for energized system

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

in a raised position

4. This Happens often

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

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

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

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

10. 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

11. Some Types of Energy
Electrical
Mechanical
Chemical
Thermal
Hydraulic
Pneumatic

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

13. Potential Energy
(Gravity)

14. LOTO Procedure
1. Prepare for shutdown
2. Shutdown equipment
3. Isolate all energy sources
4. Apply locks & tags
5. Verify isolation
6. Control stored energy
7. Prepare for Startup

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

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

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

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

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

20. 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

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

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

23. 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

24. 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

25. 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

27. Contractors
All contractor employees
must follow plant LOTO
procedures!

28. 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

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

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

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

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