When the job is completed, ensure locks and tags are removed and stored back in the LOTO Board and fuses are re-installed and notify all affected personnel.
Inspect work area with PICW to ensure that nonessential items have been removed, employees have been safely removed, and temporary protective grounds/earths or spring tension blocks are removed. The equipment can now be energized and Permit to Work closed.
The LOCK NUMBER Directory shall be updated regarding the executed LOTO Plan, and the plan shall be safely stored in the binder and/or electronically in the job file.
c) Preparations:
Preparing Equipment LOTO Directory. The LOTO Directory shall contain a list of electrical equipment with all energy isolation devices. (Disconnect Switches, MCBs, MCCBs, Fuses, etc.) with their status: Unlocked, Open locked and tagged out, not locked – spare, or Fuse removed, bagged, and tagged out. It shall contain LOTO date and name of the Authorized Person for each energy isolation device, MCB, MCCB, Fuse, etc.).?
Preparing the list of LOTO devices, which must be sufficient for Locking & Tagging all lockable energy isolation devices, MCBs, MCCBs, etc. ?
Ordering LOTO equipment according to the Site Purchasing Standard.?
Preparing the group LOTO box(es) and LOTO board(s) for storing equipment locks, tags, and other LOTO devices.?
Preparing the lockable LOTO panel for keeping and organizing the removed fuses.?
Preparing Warning signs for entire site.?
Preparing and organizing all Site Temporary Earthing Devices.
Padlock numbering (each lock shall have its number, and one key only) and organizing the LOTO Board.?
Experience:
Minimum 5-7 year of experience performing Lockout/Tagout Coordinator related tasks. This person will need to be able to read and interpret electrical drawings, schematics, and control wiring. A former Journeyman Electrician is desirable, but not a must.
