3 Fluke Corporation Standardizing on clamp meters for HVAC service
Growing green facilities
MacDonald-Miller has another, greener arm
of the business. Led by Perry England, the
sustainable, eco-friendly Building Performance
group helps customers plan, build, retrofit,
and maintain building environmental systems
for maximum efficiency and reliability.
Following LEED, Green Globes, Lean
Design, and other practices, the group has
built a uniquely integrated understanding of
green building automation technologies. Some
classic reliability practices transfer over, such
as preventive maintenance and equipment
modernization. What’s different is the layer of
documentation and highly networked tools for
data analysis and trending. England says the
change makes good business sense.
Customers are demanding green building
efficiency and changes in financial lending
models increasingly support it.
Safety first
Safety is an area of increasing
concern for everyone involved
in electrical work. Sundby cites
increasing emphasis on the
requirements of the NFPA 70E
Standard for Electrical Safety
in the Workplace. The standard
covers electrical safety require-
ments for employees involved
in the installation of electric
conductors, electric equipment,
signaling and communications
conductors and equipment, and
raceways. A big part of it is con-
cerned with protection against
Arc-Flash. While the standard
has been around since 1996,
Sundby says, it has moved to
the forefront, starting with a
change in clothing. Polyester is
out, and flame retardant cotton is
in, along with the proper gloves.
Lockout/Tagout is getting more
attention as well, but the work
that the MacDonald-Miller field
techs do involves live equipment:
“You can’t do too much testing on
equipment that’s sitting there,”
he says.
Summary
MacDonald-Miller’s servicing
operation must handle a wide
variety of tasks on different types
of equipment. By standardizing
on just a few Fluke instruments
and by providing its people
with strong training and support
the company has been able to
increase the effectiveness of its
operations and cut costs at the
same time. All in all, it’s a win-
win situation.
