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
