You and CMMS, Part

management system (CMMS) uses it to schedule and track maintenance —
and nearly everyone underutilizes it. The early CMMS products put paper

whereby scheduling them together saves time and money. Consider timing

solve this problem. You look in the CMMS and find that the main drive
motor has been aligned three times. There was no "as found" or "as

Some Repairs Matter
More Than Others,
Equipment that makes the most money per hour and/or has
the tightest delivery schedule usually must be fixed under
pressure-cooker conditions. How is your record on this?
If you look in the repair logs, do you see shorter repair times for
the same types of repairs as you go from earlier repairs to more recent
ones? Why or why not?
Urgency sometimes leads to counterproductive decisions. The
palletizer is down, so the first available tech is sent there. However,
that tech hasn't done a repair on this equipment before and isn't even
familiar with it. After lots of head scratching and research, all of
which have been done by somebody else on previous repairs, the tech
begins actual troubleshooting.

NEC in the
In the previous issue of this newsletter, we looked at
some electrical inspection rules covered in 80.13 (in Annex H). Also in
80.13, we find that the authority having jurisdiction (AHJ) has the
authority to conduct investigations of electrical fires, explosions, or
other hazardous conditions [80.13(11)]. This is one of the five major
functions identified in 80.1.
But who determines who the AHJ is? "The governing body" does
Just who is this "governing body?" It's the "electrical board," and we
find the requirements for it in 80.15.
Each state determines which standard to adopt as its electrical
regulations. This may be the current NEC. In some cases, it's the
previous edition of the NEC with the state's amendments.

In recent years, you've probably heard about NFPA 70E
far more often than you previously did. But it's no simple document.
Here are three key concepts to understand so you can properly apply
- Understand that OSHA's position has always been to de-energize
equipment before any work is performed on it.
- Don't ask, "What can I get by with?" and try to finesse the
requirements. Instead, ask, "How can I protect myself from arc blast
arc flash while servicing this equipment?"
- Use the arc flash label (required by the NEC 110.16) as a point of
reference, not as an authoritative determination of whether arc flash
hazards exist and to what degree. Note that absence of a label does not
mean absence of arc flash danger.

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. Check out the following conferences for a
and time that's right for you.
- Philadelphia November 29-30, Hilton Philadelphia City
- Boston December 7-8, Venue to be determined
- Orlando December 13-14, Hyatt Regency Orlando
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
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 one of the these events. For more details on the conferences and
a full program, visit EC&M's website.
