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.

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?

Operation
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."
