Lockout/Tagout



About this Presentation

By the end of this presentation, you’ll be able to:

Recognize the when, how and why of lockout/tagout procedures

Spot dangerous violations, and

Minimize the chances of serious injury.



What is lockout/tagout?

Lockout/tagout is the isolation of all energy sources with a lock – and a tag explaining why the lock is there – BEFORE servicing any piece of equipment or machinery.



The OSHA Standard

OSHA Standard for the Control of Hazardous Energy (Lockout/Tagout)

It covers the servicing and maintenance of machines and equipment in which the unexpected energization, start-up or release of stored energy could injure employees.



Key lockout/tagout definitions - #1

Authorized employee – An employee who performs servicing or maintenance on machines and equipment. A person who locks and tags machines or equipment in order to perform service or maintenance on that machine or equipment.



Key lockout/tagout definitions - #2

Affected employee – An employee whose job requires him to use a machine or equipment on which maintenance is being performed under lockout/tagout, or whose job requires her to work in an area where service or maintenance is being performed.

Affected employees must be told when any lockout/tagout is to be performed.



Why is lockout/tagout important?

Because it’s the only reliable way to avoid injuries or death to workers servicing machinery.

It’s important for all employees to understand lockout/tagout procedures, how and when to use them and how to safely restart the equipment or machinery.



Why even good workers ignore lockout/tagout

They think turning off the power or unplugging the machine is good enough.

They don’t want to interrupt production.

They think they’re experienced enough to avoid injury.



Exceptions to lockout/tagout

Minor service activities during normal production

Routine, repetitive adjustment

Minor tool changes



Electrical Energy – flow of electrons through a conductor.

Kinetic (Moving) Energy – force caused by an object’s motion.

Hydraulic Energy – force caused by pressurized fluid, especially water.

Pneumatic Energy – force caused by compressed air.

Potential (Stored) Energy – force stored in an object that isn’t moving.

Thermal Energy – increased heat of a fluid or object.

Six types of energy sources that pose potential dangers



Example #1 of potential energy danger – gravity

What is up will come down, unless you lock it out.



Example #2 of potential energy danger – hydraulic

Fluids under pressure can burst out unpredictably, or cause dangerous machinery to move, if lockout/tagout isn’t performed.



Other examples of potential energy danger

Energy risks may exist in your personal environment at work.

Can you identify them?



Lockout/Tagout Equipment

Personalized, standardized lock

Personalized, standardized tag

Hasp, or multiple lockout device, when machinery won’t accept multiple locks



Lockout/tagout musts

Notify

De-energize

Release or restrain stored energy

Check locks and/or tags for defects

Place lock and/or tag

Test machinery to ensure it is de-energized



Putting equipment back on line

Check for tools and materials

Notify workers and make sure everyone is clear

Have each person remove locks and/or tags

Start and test the machine

Return machine to production or de-energize through lockout/tagout



Frequent violations

1. Ignoring the rule because somebody thinks he doesn’t need it.

2. Misusing the lockout/tagout equipment.

3. Doing an incomplete lockout/tagout that leaves out a source or a circuit.

4. Failing to check the safety of the lockout.

5. Using a single lockout device for more than one worker.



Violation #1. Ignoring the rules…

May be among your smartest employees – that can lead to overconfidence and a feeling of invulnerability.

May have the best of intentions – they feel that speed is important and they can get the job done faster without locking and tagging out.

Are risking serious injury.



Consequences of non-compliance may be fatal

Machinery harnesses powerful forces to bend, shape and cut materials much more resistant than the human body.

The human body is no match for these forces.



Violation #2. Misusing the lockout/tagout equipment

Duplicating keys.

Using lockout locks for other purposes.

Using control tags as information tags.



A. Duplicate keys

Best practice is to have individually keyed locks, with no duplicates available.

If bolt cutters must be used to remove a lock, that will make people think twice before endangering others.



B. Unauthorized use and loss of locks

Lockout locks are usually high-quality equipment. Workers may be tempted to use them on their lockers or toolboxes. A surprise inspection of lockout locks can catch and remedy these misuses.

Another point: If a lock is lost, the worker shouldn’t attempt to do his job without it. A periodic “roll call” can turn up any unreported lost locks.



C. Control tags

Control tags are for warning workers of the danger of reopening the circuit or valve while maintenance is going on.

They shouldn’t be used to record general information about maintenance or the process.



Violation #3. Doing an incomplete lockout

Machines may have more than one circuit or assembly.

Locking out only one path, while leaving others on, represents a clear danger.



Violation #4. Failing to check the lockout/tagout

Verify that the lock is working and the tag is legible.

Check that the locked-out machine is truly isolated from all energy sources.



Violation #5. Using a single lockout device for multiple workers.

Nobody watches your back like yourself. That’s the philosophy behind doing multiple lockouts when multiple workers are involved in a maintenance project.

Using a single lockout device creates the risk that when that worker finishes and unlocks, remaining workers can be hurt or killed if the machine starts up again.



Workers comp & LO/TO

If lockout/tagout procedures are clearly explained and enforced, and you violate them and are injured, you may lose all or part of your workers compensation entitlement.



Summary

Take personal responsibility for safety in locking and tagging out. The ownership you take for your behavior can save your life and the lives of others.

Here’s what can happen if you don’t:

You can be seriously injured and you may injure someone else.

You can lose all or part of your workers comp benefits.

You can be disciplined or fired, depending on how grave the violation was.
