DESCRIPTION
The
FallTech®
Contractor
Series
Cable
SRD
is
a
self
‐
retracting
device
for
those
working
at
height
and
subject
to
fall
hazards.
This
manual
contains
two
Appendices,
Appendix
A
and
Appendix
B.
Appendix
A
contains
figures
and
tables
specific
to
the
Contractor
Cable
SRD
discussed
in
this
manual.
Appendix
B
contains
figures
and
tables
applicable
to
fall
protection
equipment
in
general.
All
figure,
table,
and
chart
references
in
this
manual
are
to
Appendix
A
unless
otherwise
noted.
For
purposes
of
this
manual,
the
Contractor
Cable
SRD
in
all
iterations
may
be
referred
to
collectively
as
the
SRD,
the
equipment,
the
device,
the
product,
or
the
unit.
The
SRD
consists
of
a
self
‐
closing,
self
‐
locking
housing
end
carabiner
fitted
to
an
attachment
eye
on
a
glass
‐
filled
nylon
housing
with
an
external
webbing
and
rubber
handle.
The
housing
contains
a
lifeline
composed
of
various
lengths
of
galvanized
wire
rope,
wound
onto
a
spring
‐
tensioned
drum.
The
SRD
is
equipped
with
a
spring
and
rubber
ball
dampener
to
limit
freewheel
impacts,
with
a
swaged
eye
and
a
swiveling,
impact
‐
indicating
carabiner.
See
Figure
1
for
an
illustration
of
the
product.
See
Table
1
for
product
and
materials
specifications,
ratings,
and
capacities.
When
the
user
is
attached,
the
lifeline
extends
and
retracts,
automatically
maintaining
a
taut
line.
If
a
fall
occurs,
a
centrifugal
system
applies
a
brake,
slowing
and
arresting
the
fall.
1.1
American
National
Standards
Institute
(ANSI)
and
Occupational
Safety
and
Health
Act
(OSHA):
The
SRD
discussed
in
this
manual
meets
the
standards
of
ANSI
Z359.14
‐
2012,
ANSI
A10.32
‐
2012,
and
Occupational
Safety
and
Health
Act
(OSHA)
regulations
1926.502.
SRD
Class
A
and
B:
ANSI
requires
SRDs
be
classified
according
to
their
tested
dynamic
performance,
and
are
classified
either
Class
A
or
Class
B,
based
on
those
test
results.
Dynamic
performance
means
that
the
SRD
is
installed
in
a
testing
drop
tower
that
will
simulate
real
‐
world
ambient
conditions.
A
test
weight
is
attached
to
the
SRD
and
then
dropped.
Instruments
record
the
test
results.
Parameters
tested
are:
Arrest
Distance
(AD)
Average
Arrest
Force
(AAF)
Maximum
Peak
Arrest
Force
(MPAF)
The
Arrest
Distance
is
the
total
vertical
distance
required
to
arrest
a
fall.
The
Arrest
Distance
includes
the
deceleration
distance
and
the
activation
distance.
The
Average
Arrest
Force
is
the
average
of
the
forces
applied
to
the
body
and
the
anchorage
by
the
fall
protection
system.
The
Maximum
Peak
Arrest
Force
is
the
maximum
amount
of
force
that
may
be
applied
to
the
body
and
the
anchorage
by
the
fall
protection
system.
In
addition
to
the
above
tests
conducted
in
ambient
conditions,
the
units
must
be
retested
for
average
and
peak
forces
under
certain
environmental
conditions,
where
the
units
are
cooled,
then
tested,
heated,
then
tested,
and
saturated
in
water
and
tested
again.
Separate
units
may
be
used
for
each
test.
All
test
results
are
recorded.
This
test
data
is
then
used
to
establish
the
basis
for
fall
clearance
guidelines
published
in
the
user
instruction
manual.
To
be
declared
a
Class
A
device,
ANSI
requires
an
SRD
to
have
an
Arrest
Distance
of
less
than
24",
an
Average
Arrest
Force
of
less
than
1350
lbs.,
(1575
lbs.
conditioned)
and
a
Maximum
Peak
Arresting
Force
of
1800
lbs.,
for
both
ambient
and
conditioned
testing.
To
be
declared
a
Class
B
device,
the
SRD
must
have
an
Arrest
Distance
of
less
than
54",
an
Average
Arrest
Force
of
less
than
900
lbs.,
(1125
lbs.
conditioned)
and
a
Maximum
Peak
Arresting
Force
of
1800
lbs.,
for
both
ambient
and
conditioned
testing.
When
dynamically
tested
in
accordance
with
requirements
of
ANSI
Z359.14
‐
2012,
FallTech
Class
A
Self
‐
Retracting
Devices
have
an
AAF
of
less
than
1350
lbs.
and
an
AD
of
less
than
24".
When
dynamically
tested
in
accordance
with
requirements
of
ANSI
Z359.14
‐
2012,
FallTech
Class
B
Self
‐
Retracting
Devices
have
an
AAF
of
900
lbs.
and
an
AD
of
less
than
54".
Units
are
marked
as
Class
A
or
Class
B,
based
on
test
results.
These
test
results
are
included
in
Table
2,
for
use
by
the
qualified
person
as
an
aid
in
determining
anchor
requirements.
See
paragraph
3.5.1.
NOTE:
Arrest
distance
is
one
part
of
the
MRFC.
The
MRFC
is
determined
by
consideration
of
multiple
factors
in
fall
protection.
MRFC
is
discussed
in
detail
in
Section
4.
OSHA
requires
the
SRD
to
limit
the
free
fall
to
2
feet
or
less.
If
the
maximum
free
fall
distance
must
be
exceeded,
the
employer
must
document,
based
on
test
data,
that
the
maximum
arresting
force
will
not
be
exceeded,
and
the
personal
fall
arrest
system
will
function
properly.
2.
APPLICATION
2.1
Purpose:
A

a
combination
of
worker
mobility
and
fall
protection
