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

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.

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”
![Page 22: Lockout/Tagout (The Control of Hazardous Energy)](https://reader035.vdocuments.site/reader035/viewer/2022062320/56649d845503460f94a6b2b2/html5/thumbnails/22.jpg)
TagoutTagout
• A tag is a visual warning (not a physical restraint)
• Use as a supplement to a lockout device for best results
