1. Lockout/Tagout is a method of keeping equipment from being set in motion and endangering workers.
  2. Lockout/Tagout is necessary whenever you are performing service or maintenance around any machine where you could be injured by unexpected startup or movement. The most common situations that require Lockout/Tagout are:
    when you  remove or bypass a guard or other safety device
    b.      when you  place any part of your body where it could be caught by moving machinery
    c.       when using electrical circuits
  3. Whether the power switch is on or off, energy could be present in equipment.
  4. Stored energy poses special problems. Be aware of the power source, i.e. hydraulic pressure, steam, electric charge, etc. Dissipate all residual energy prior to working.
  5. Energy controls are applied according to a six step procedure:
    a.       Preparation for shutdown
    b.      Equipment shutdown
    c.       Equipment isolation
    d.      Application of Lockout/Tagout devices
    e.      Control of stored energy
    f.         Equipment isolation verification

Removal of Lockout/Tagout

  1. Prior to removing Lockout/Tagout devices, determine if the equipment is safe to operate by removing all tools and verifying that the system is fully assembled.
  2. The Lockout/Tagout devices should be removed by the person who put them on, except in an emergency.
  3.  When the worker who applied a lock is not present to remove the lock, it can be removed only in an emergency, and only under the direction of the supervisor.
  4. Follow the manufacturers checklist to re-energize the system.
  5.  If an outside contractor or other outside worker is performing service or maintenance, they should coordinate their activities with the Electrical Department or other appropriate department.
  6. See to it that Lockout/Tagout protection remains in effect when switching shifts.
  7.  Never remove a lock until you are absolutely sure that it is completely safe to do so.
