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!
