Why Lockout/Tagout?Why Lockout/Tagout?

When is LO/TO Required?When is LO/TO Required?

When someone will be servicing or repairing machinery or equipment

AND

The unexpected machinery start-up or release of stored energy could cause injury

Who Needs Training?Who Needs Training?

Authorized employees – People who lock or tag out machines or equipment to perform servicing

Affected employees – People who use machines or equipment on which servicing is performed under lockout/tagout

Other employees – People who work in the area of locked out machinery or equipment

What is Hazardous Energy?What is Hazardous Energy?

Electricity – live or stored

Moving machinery parts

Stored mechanical movement in machinery

What is Hazardous Energy?What is Hazardous Energy?

Stored heat (steam lines or hot liquids)

Chemicals in pipelines under pressure or force of gravity

Any other active or stored energy sources that could harm a worker

Hazardous Energy Source ExamplesHazardous Energy Source Examples

Live electrical lines

Electrical capacitors

Lasers

Engines that move machinery parts

Hydraulic lifts

Pneumatic (air pressure) lines

Springs

Service and MaintenanceService and Maintenance

Adjusting Lubricating Set-up (Preparing for

normal function) Service/Repair

These activities often require a worker to place all or part of his body into the machine’s hazard zone.

What is a Lockout Device?What is a Lockout Device?

A device that:

Prevents a machine from being started up or turned on

Prevents a machinery part from moving

Prevents electrical energizing

Blocks a pipeline, steam line or air line

Group Lockout DevicesGroup Lockout Devices

Used when more than one person doing maintenance or repair on same machine or equipment

Machinery or equipment can not be started up until all locks are removed

Each person places and removes their own lock

What is Tagout?What is Tagout?

Tags are warning devices only

They do not provide the same level of protection as lockout devicesThey can only be used alone if there is no other way to “positively control hazardous energy”

TagoutTagout

• A tag is a visual warning (not a physical restraint)

• Use as a supplement to a lockout device for best results
