Lockout - Tagout
Control Of Hazardous Energy
You Will Learn… Purpose of lockout-tagout Requirements for LOTO Types of hazardous energy Procedures for LOTO
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
This Happens Often
Employee accidentally leaned on the start switch & turned on the machine himself...
Lockout Prevents release of hazardous
energy Lock placed on appropriate
energy isolating device that is in the off or closed position
Tagout Identifies problem Identifies lockout
date Identifies person Used by itself only
when cannot be locked out
Lockout/Tagout Use
Repaired Serviced Lubricated Cleaned Un-jammed Adjusted Maintained Guard removed
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
Some Types of Energy
Electrical Mechanical Chemical Thermal Hydraulic Pneumatic
Mechanical Energy Kinetic - machinery in motion–Gears
–Belts Potential - stored energy–Weights (gravity) & springs
–Pistons under pressure
–Hydraulic controls
Potential Energy (Gravity)
LOTO Procedure1. 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
1. Prepare Plan your work & locate
instructions Understand equipment
hazards Notify others of shutdown
2. Shutdown Normal shutdown procedure Turn all switches to OFF Shut all control valves
3. Isolate Sources Disable all
energy sources
Shut valves Open breakers
& disconnects
4. Apply Locks Valves Breaker &
electrical disconnects
Block or disconnect all lines
Lockout Devices Plug locks Ball valve Gate valve Hasp
Electrical Hydraulic Pneumatic
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
5. Verification Prior to servicing or
maintenance, authorized employee must verify that equipment is isolated by turning it on
6. Control Stored Energy
Block or release springs or other tension
Block elevated parts Stop rotating flywheels Relieve system pressure Drain fluids Vent gases
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
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
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
Contractors All contractor employees
must follow plant LOTO procedures!
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

Adequate Blocking?
How did he get this blocked?
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.
Sometimes the Instructions Are Handy
What is This Pin For?
Is This Machine Blocked Adequately?
How is This For Blocking?
Works for Me but What’s The Wire For?
Locked and Tagged, But Tag Could Be Improved!
