Lean Tips

Maintaining doors
Keeping doors repaired and closed makes
environmental and fiscal sense
BY DR. GLEN MILLER

or this Lean Tip, I called some of
my friends in the industry. I wanted current information on sustainability so I asked them this question.
"What environmental issue gives you
the most problems and what can be
done about it?"
The response from Rod Perry, director of maintenance at a ground beef
processor in Georgia, caught me by
surprise. Rod has significant maintenance experience in a variety of food
processing plants located in various
geographical climates. He said, "Door
maintenance is my biggest problem."
At first I thought he misunderstood my
question. Then he explained, "Door

F

maintenance is important to keep
the doors leak-proof." I was still trying to connect the dots between door
maintenance and environmental issues when he said, "You know, we inspect and fix the doors to keep 50°F
air from following the laws of heat
transfer right into the 30°F room."
Doors seem to get routine dents from
various equipment, particularly forklift trucks. Dents cause leaks. Leaks
cause drafts or allow air flow. This is
not good for maintaining proper temperatures throughout a ground beef
or any food processing plant.
Rod said just closing doors is an
important part of temperature reg-

ulation. In Georgia, where he now
works, it is often hot and humid. Humid air enters the plant through open
or damaged doors and "eats up energy for evaporators." The evaporators run more with less benefit. Eventually, moisture from the humid air
freezes the coils, coolers run harder
and more energy is wasted.
In the past, Rod and I have worked
on some Lean deployment projects.
As advocates of Lean, we often discuss how seemingly little things
mount up. In fact, part of Lean
thinking or Lean philosophy is that
"taking care of the little things" can
greatly reduce the cost of running a
