    Maintenance
    Maintenance Fads vs. Reality
    If you’ve been in maintenance very long, you’ve seen fads come and go. Maintenance fads generally possess the following characteristics:
    • The training is heavy on new buzzwords, making the program appear to be some sort of "new science."
    • The program originates with a paper presented by a single company (not an industry group), whose staff established its credentials in fields other than maintenance.
    • The program either repackages maintenance knowledge/standards or prescribes a new system detached from existing maintenance standards.
    New maintenance practices can be not only worthwhile, but also game-changing. They can even come from manufacturers and service providers, rather than maintenance practitioners. But they need to be reality-based, or they’ll catch fire and then flame out. In our next issue, we’ll look at characteristics of reality-based maintenance practices.

    Repair
    Electrical Troubleshooting Quiz
    A few weeks ago, a 400A feeder breaker started exhibiting nuisance trips. DMM measurements, taken randomly, show the breaker is nowhere close to its maximum load. During shift changes over the weekend, another electrician performed the recommended maintenance on it. Yet, it still trips for no apparent reason.

    Your boss has asked you to replace the breaker. What are some things you should do before carrying out that request?

    Visit EC&M's Web site to see the answer.


    Overcurrent Protection Device Replacement
    What happens when a fuse blows or a breaker fails its maintenance inspection? You replace it with one just like it, right? But how do you know the existing overcurrent protection device (OCPD) is correct in the first place?

    NEC in the Facility
    If you have flammables on site, the first few Articles in Chapter 5 of the NEC are important to you. One question that arises in relation to these is, "What’s the difference between Zones and Divisions?"

    Safety
    Sometimes, you just need a little help from a friend or coworker — especially when it comes to moving parts and materials.

    How much weight you can lift and how much you should lift can be vastly different numbers. You might have an impressive bench press at the gym, but that doesn’t always translate into safe lifting on the job.

    If you start to lift something and it feels even slightly awkward, stop and ask for help. An unexpected shift in a load can take your healthy back into hernia land.

    Another danger is that of blocking your view. Do you need to move that 4×8 plywood out of the way? Ask someone to grab the other side.

    Proper lifting methods reduce the chance of injury. Asking for help reduces the chance of injury even more. Using lifting equipment provides further risk reduction.

    The flipside of asking for help is giving help when asked. Doing so helps promote an "ask-for-help" culture. Caution: Even with your help, the lift might not be safe. Before you put your back, fingers, knees, or other body parts at risk, evaluate the lifting task. Don’t be afraid to put conditions on helping. For example, "I’ll be happy to help you, but we need to lift this motor with a sling and hoist."
