Engineer issues out - Identify fault level studies, load flow analysis, set protection gradings, conduct arc flash study, update all distribution system records.
Eliminate pre identify risks, implement procedures and label equipment correctly.
Mitigate (moderate dangers to make them less severe) - via procedures and training.
