When Lockout/Tagout Devices Must Be Used

– Servicing or maintaining machinery or equipment

– Hazardous energy exists

– Unexpected start-up could occur


Actions That Trigger Lockout/Tagout

– Removing or bypassing a safety device

– Any part of the body is placed in harm’s way

– Exposure to hazardous energy


Lockout/Tagout Exceptions

– Work where the potential for hazardous energy does not exist

– Activities performed during routine production processes

– Work on cord-controlled devices

– Hot tap operations where shutdown is not feasible



Lockout/Tagout Procedure

Authorized employee will:• Notify affected employees• Shut down energized equipment• Isolate energy sources from equipment• Lock out or tag out the energy isolation device• Release stored energy• Test


Restart Procedure

Authorized employee will:• Clean up and inspect work area• Clear personnel from start-up

area and notify affected employees of start-up

• Remove lockout devices or tags and reenergize machinery or equipment

• Restart equipment


Lockout/Tagout Devices and Procedures

– Do you understand the information presented in the previous slides?


Key Points to Remember

– Hazardous energy is dangerous and deadly– Lockout/tagout is used whenever unexpected
