    Maintenance
    You and CMMS, Part 8
    How can you use your CMMS for charting, reporting, and analysis (CRA)? You have two options:
    1. Use its built-in CRA tools (if they exist and are robust).
    2. Use Excel for CRA (export data from your CMMS).
    Because your CRA is only as good as the data you collect and input to the CMMS, start with good data collection rules. It's normal to not have good data collection rules in place, so don't assume you have such rules. Your CMMS vendor should be able to help you set these up for your specific needs.

    Focus on problems you must solve, not on how much data you can gather.

    Electrical Troubleshooting Quiz
    You work at an 11-building site in which new buildings have been added over time. The buildings share a wired network that began in the late 1990s. Each building is on its own network node, and each node connects to the main network switch via buried coaxial cable.

    Over the summer, occupants in three of the buildings often complained about bandwidth limits. One of the other buildings lost network connectivity entirely, and that problem was fixed by laying a new cable (the old one was abandoned in place). This same scenario took place last summer. Your COO does not feel three is a charm; he is talking more along the lines of "three strikes and you're out."

    What should you test and what should you propose so that next summer is different?

    Visit EC&M's website to see the answer.
    Some Repairs Matter More Than Others,
    Part 5
    When equipment is so critical that every minute of downtime is costly, you don't want something as manageable as spare parts holding things up. Here are some pointers:

    • Often, the problem is a fuse. Store replacement fuses at critical equipment, and establish a min/max system. You don't want to be out of a fuse for critical equipment simply because someone used the last one on minor equipment.
    • Make a list of the components most likely to fail. Now, look at the process for replacing those. Would it reduce downtime to swap out an entire assembly rather than replace that single component? One example is a critical gearbox. Removing and replacing one bearing might take an hour, while removing and replacing the entire box might take 15 min.; keep an entire box in stock, reserved for this machine.
    • Determine if repair requires special lubricants, connectors, or cables. Keep those with the machine.
    There's one more resource you need to provide, as you'll see in our next issue.

    Operation
    NEC in the Facility
    What happens when you just cannot agree with the electrical inspector or other AHJ? You can appeal the decision if you meet any of these three conditions:
    1. The inspector's decision doesn't meet the true intent of the Code.
    2. The provisions of the Code do not apply to this specific situation.
    3. The decision is arbitrary or unreasonable (as it applies to alternatives or new materials).
    You have 15 days from the AHJ's decision to submit a written appeal to the Electrical Board [80.15(G)]. In this appeal, first summarize the disagreement (preferably in a few clear sentences). Then explain the disagreement in detail in a few pages or less, if possible.

    Safety
    Labels and MSDS are two safety information resources you should review before using any chemical. From these, you can determine:

    • Emergency and spill cleanup procedures.
    • First Aid.
    • Limits of exposure.
    • Physical hazards.
    • Precautions to avoid exposure.

    Shows & Events
    Code Change Conferences Are Coming
    The 2011 NEC is coming. Will you be ready for the changes? By attending one of EC&M's Code Change Conferences, presented by NEC expert Mike Holt and sponsored by EC&M University, you'll learn everything you need to know about major NEC changes that will impact your work, whether you're an electrician, electrical engineer, electrical designer, plant/facility electrical maintenance person, or electrical inspector. The last conference of 2010 is scheduled for:

    • Orlando December 13-14, Hyatt Regency Orlando Airport

    If you're a registered professional engineer and attend one of the 2011 NEC Code Change Conferences, you'll be granted professional development hours (PDHs), a requirement for re-licensing. The program is also certified as an approved provider of Code Update training by those states requiring continuing education hours for re-licensing of journeymen, master electricians, and electrical contractors.

    Register now to attend this event. For more details on the conference and a full program, visit EC&M's website.
