Lockout A technique used to prevent hazardous energy from escaping. A padlock is placed on a disconnect switch, circuit breaker, valve handle or other energy-isolating mechanism that is in the off or closed position.

Tag Out Energy isolating device is placed in the safe position and a written warning tag is attached. This warning tag must have the authorized users name and department.

Who Can Lockout Equipment? Only Employees who have been trained and authorized by management and have received the proper equipment

Authorized vs Affected Employees Personnel trained to lockout-tagout machines or equipment to perform servicing or maintenance on that machine or piece of equipment is the AUTHORIZED employee. The employee whose job requires operating or use of a machine or equipment on which servicing or maintenance is being performed is the AFFECTED personnel.

Use your own Lockout Tagout device Every single authorized employee working on a system shall independently lockout and/or tagout the system using his or her own lock and/or tag eliminates the possibility of others inadvertently unlocking an isolation device when it is being worked on by another. at no time should any employee depend on the lock or tag of another worker to protect them during their service activities.

Next Steps 5. Apply lockout / tagout device At all disconnects, valves and energy isolating devices 6. Control STORED energy Relieve disconnect or restrain residual energy that COULD be present 7. Verify Isolation of equipment Dont take anything for granted. Double check !

The Fatal Five Failure to stop equipment Failure to disconnect from power source Failure to dissipate (bleed, neutralize) residual energy Accidental restarting of equipment Failure to clear work areas before restarting

Removing locks and tags 1.Make sure equipment is operationally intact 2.Remove tools and non-essentials 3.Tell all affected employees(head count) 4.Make sure area is clear 5.Remove lockout /tagout devices Each worker removes their own lock/tag 7.Tell affected employees locks and tags have been removed and equipment is ready to use
