Bad maintenance practices tend to sneak into the way things get done. Here are three more to guard against:
Bad Practice #26 — Not Updating Drawings Prior to an Outage.
For example, certain cabinets were upgraded with interlocks and alarms for security and safety purposes. These need to be tested during the outage. Do the drawings show these upgrades, or will techs have to second-guess the system during the limited downtime window?
Bad Practice #27 — Planning an Outage without Detailed Visual Inspections of Critical Equipment.
It's probably too late to do anything about it when, on the last day of the outage, a tech sees fluid around a transformer or spots some other critical problem. Transformer oil testing several months prior to an outage is also a very good idea.
Bad Practice #28 — Not Pre-Fixing the Easy Stuff Prior to an Outage.
You should fix "non-outage" problems before the outage so the outage is more efficient; overtime may be cost-effective here. Do a walkdown and generate a punchlist. Examples: missing covers, missing screws, bonding jumper problems, and non-functioning lamps.
