In the early days of CMMS, smart maintenance people
exported data to a spreadsheet (typically, Lotus 123 or Borland Quattro
Pro) to extract useful information. The sheer time consumption limited
the amount of information extracted.
With today's relational database CMMS products (typically SQL

dice however you need, and you can add drilldowns.
You can also quickly compare metrics. You could, for example, see the

Some Repairs Matter
More Than Others,
In our previous issue, we said that for your most
critical equipment, you should make a list of the 10 most likely
modes. And by “critical,” we mean “revenue-intensive,” as
determined by the operations managers. So, what should you do with this
Starting with the most critical piece of equipment and working your way
down from there, do the following:
There's more you need to do with this list, as you'll see in our next
- Provide a concise troubleshooting guide that will allow any tech to
determine which of the 10 failure modes is the problem.
- Provide all manuals, instructions, and drawings for affecting the
repair. Put these items into a kit, and store it at the equipment in a
durable box designated for that purpose.
- Provide all test equipment and tools needed for repairing this
specific equipment. Is this a needless expense? Answer that question by
comparing the expenditure to the revenue loss incurred when a tech has
to gather all of these things while the equipment is idle.

In our previous issue, we looked at the composition of
the electrical board. We know this board determines who the AHJ is, but
what else does it do? We can find the answer in Annex H, specifically
The board has five duties:
To sum up the list, this electrical board sets the rules for electrical
safety in its jurisdiction and has the final say on how those rules are
interpreted and implemented.
- Administer and enforce Art. 80 (which, per 80.1, means the entire
- Establish the qualifications for electrical inspectors.
- Revoke or suspend an electrical inspector's certification.
- Establish and amend electrical regulations.
- Establish procedures for recognition of electrical safety standards
and equipment acceptance.

A key concept in OSHA's requirements for hazardous
materials is that the employee has a “right to know.” This means
your employer must provide you with information about hazardous
materials you may work near or with. One way employers accomplish this
is through “hazmat” (hazardous materials) training specific to a
given job and which is often tailored to the specific hazardous
may be encountered. Notice we have used the word “may” twice now,
rather than saying “probably will.”
In your hazmat training, your employer should identify another way
informing you. That's through the use of container labels and material
safety data sheets (MSDS). This is a self-serve method, meaning it's
your responsibility to read those labels and MSDSs. Follow up
accordingly, and ask your supervisor for help or clarification if

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.

- 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.
