Lock Out Tag Out


This Safe Work Practice (SWP) will provide YG employees with a set of guidelines or “Do’s and Don’ts” that have been developed to mitigate hazards associated with this work task, as identified through your workplace hazard identification process. All YG employees performing this work task are required to be trained, knowledgeable and competent.




a)    Follow all equipment-specific procedures to shut down and lock out equipment and machinery

b)    Block  or secure parts that could inadvertently move prior to starting work on the equipment

c)    Always verify that energy has been controlled prior to starting work either at the source, or if plugged in, that the unit has been unplugged

d)    Use only workplace specific or identifiable tags to perform lockout/tag out operations

e)    Receive appropriate training on lockout/tag out procedures and processes for your workplace

f)     Notify all affected people and/or employees that a lockout is to be performed, and that they are not to disturb the lockout device or attempt to re-start equipment until informed that the work is completed

g)    Attempt a re-start of the equipment as a final check that the equipment has been isolated form it’s energy source



a)    Do not remove tags or locks from equipment while on breaks or away from the area

b)    Do not remove tags or locks until the work is completed, which could include overnight or over a weekend.

c)    Do not deviate from the equipment and/or machinery’s specific lock-out/tag-out procedure. This also applies to your workplace’s specific safe job procedure.

d)    NEVER perform any electrical or mechanical service and/or maintenance on equipment unless you are trained and authorized to do so.




This practice applies to installation, service, maintenance or removal of any type of machinery, equipment, or components, in which the unexpected start-up or release of stored energy could cause injury.

Employees performing this type of work are to ensure they have exclusive control of the lockouts used at all times, reducing likelihood of the system being re-energized without their knowledge.
