ELECTRICAL METHOD OF PROCEDURE (MOP)
UNR requires a Method of Procedure (MOP) whenever there will be an electrical
shutdown of our transmission and distribution system(s). The purpose of the MOP is:
Increase Safety.
Minimize shut down time by planning properly.
Coordinate duties between all parties involved in the shutdown process.
Improve communication and provide a clear understanding of the process.
Ensure proper PPE is used.
Have communication between the University and any contractor working the
shut-down.
MOPS should include the following:
Pre-work briefing with all that are present for the shutdown.
Include safety discussion, all potential hazards.
Job description – what will be done, when it will be done, the voltages and
location of the equipment will all need to be included.
The steps that will be followed.
Emergency procedures and collection points.
Location of emergency exits.
The levels of PPE required for each step.
Include steps for pre-use inspection of PPE.
Steps to take for Lock-out/Tag-out.
Steps for verification of voltage / rotation or other tasks to be accomplished.
How you will control access into the work area based on arc flash boundaries.
Type of meter being used for voltage verification and max voltage rating.
Lighting considerations.
