AREA CLEANLINESS
The
operation
of
650
tape
installations
has
shown
that dirt
and
dust
can be
major
sources
of
trouble
if
not
properly
controlled.
The
following
will
acquaint
you
with
facts
concerning
building
materials
and
room
maintenance:
A.
Materials
1
.
Asphalt
tile is
not as satisfactory for
650
installations
as
vinyl
or
rubber
tile,
because
it
is
more
brittle
and
there
is
a greater
tendency
to
chip
at the
edges and
to
crack
2.
"Marbleized"
tile
patterns
have been
found
to
be
difficult to
keep
clean
because
dirt
cannot be distinguished
from
the pattern.
3.
Carpeting
may
be used
but a
lint
free
and
static
free material
should
be used. This also applies
to
drapes used
for
soundproofing or
decorative
purposes
4.
Ceiling
and
wall
material
finishes
should not "dust" or
flake.
B
.
Cleaning
1.
Waxing,
when
necessary, should be kept
to
a
minimum. Some
waxes
tend
to
flake
and
this
can
seriously jeopardize
the
operating
efficiency
of the installations
from
a
dust standpoint.
The method
of
application
of
wax
should be such
that
wax
is
applied only on intended surfaces
2.
Cleaning should be done
with a
damp
mop, never dry
or wet.
Under
no circumstances can sweeping be
tolerated.
3
.
Vacuuming
has been found
effective,
if
an
external
vacuum
or an adequate
sealed or
filtered
container,
(i.e.
water-type
tank),
is
used.
4.
It
is
recommended
that
smoking
be permitted only
in
the
immediate
vicinity of the
console.
Under
no circumstances should
smoking
be
permitted
while handling
tape,
when
attending tape drives or
in
the
tape storage
area
.
Tobacco
ashes on
the tape
can cause errors
5
.
Material should not be placed on
top of
machines
.
In
addition
to
restricting the air
flow,
foreign material
may
fall
into the
machines
Tape
reels
and
machine
covers, similarly, should not be
laid
on
the
floor
or on
the
machines
