“Preventive
Maintenance”
(PM)
When
discussing
improvement
opportunities
in your
plant,
does
preventive
maintenance
ever
come
up?
I’m
sure
it does.
We are
often
in plants
when
these
discussions
take
place.
An interesting
phenomenon
is that
most
plants
haven’t
defined
what
preventive
maintenance
is,
even
though
the
topic
has
been
discussed
for
years.
Many
feel
it is
obvious
what
preventive
maintenance
is,
is it
really?
Test
it in
your
plant
next
time
you
are
discussing
preventive
maintenance.
Ask
specific
questions
such
as:
“Is
detailed
cleaning
of equipment
included?”
or:
“is
good
operating
practices
part
of PM?”
and
“Is
balancing
part
of our
PM’s?”
IDCON’s
definition
of PM
is the
following:
“All
actions
performed
to prevent
failures
or detect
failures
early”
To
define
PM further
we can
use
