POSITIONING:
OSHA
requires
that
positioning
devices
shall
be
secured
to
an
anchorage
able
to
support
at
least
twice
the
potential
impact
load
of
an
employee’s
fall
or
3,000
lbs.,
whichever
is
greater.
Each
work
positioning
system
installation
must
be
independently
capable
of
sustaining
these
loads.
A
free
fall
of
not
more
than
24”
(60.1
cm)
is
permissible.
SUSPENSION
:
Anchorages
for
suspension
applications
must
support
a
minimum
of
5,000
lbs.
per
worker
attached.
RESCUE:
Anchorages
for
rescue
applications
must
support
a
minimum
of
5,000
lbs.
per
worker
attached.

INSTALLATION
AND
OPERATION
4.1
Inspection:
Before
every
use,
inspect
the
carabiner
to
ensure
its
proper
working
order.
Check
for
worn
or
damaged
parts.
Inspect
for
sharp
edges,
burrs,
cracks,
distortion,
or
corrosion.
Gates
must
close
and
lock.
Inspect
other
fall
arrest
or
restraint
equipment
according
to
manufacturer's
instructions.
Remove
the
carabiner
from
service
if
inspection
reveals
an
unsafe
condition.
4.2
Plan
for
the
application:
Identify
hazards
and
evaluate
the
work
site.
Consult
the
application
information
in
this
manual.
Do
not
misuse
the
equipment.
Serious
injury
or
death
may
result.
Know
the
limits
and
capacities,
stated
elsewhere
in
this
manual,
for
this
equipment.
DO
NOT
use
the
equipment
in
a
PFAS
where
there
is
a
possibility
of
a
swing
fall
that
might
result
in
striking
an
object
or
contacting
the
ground
or
the
lower
level.
Attach
the
carabiner,
and
perform
necessary
tasks,
directly
under
the
attachment
point.
Ensure
the
anchorage
location
provides
a
continuous
connection
for
the
user
when
exposed
to
fall
hazards.
Select
anchorages
that
are
stable
and
have
the
strength
required.
Select
anchorage
locations
to:
Maintain
a
maximum
free
fall
distance
of
six
feet.
Prevent
swing
fall
hazards.
Provide
clear
space
in
the
potential
fall
paths
to
avoid
striking
an
object.
See
the
equipment
provider’s
instructions
regarding
fall
distance,
swing
fall
hazards
and
clear
fall
paths.
4.3
Fall
Clearance
Distance:
When
working
at
heights
and
using
a
PFAS,
it
is
important
to
consider
the
distance
between
the
walking/working
level
and
the
next
lower
level
to
ensure
there
is
sufficient
room
for
the
PFAS
to
arrest
a
fall.
Fall
Clearance
Distance
is
the
distance
that
is
required
to
safely
arrest
the
fall
of
a
user.
The
Distance
may
be
calculated
by
adding
together
the
Length
of
the
Lanyard,
the
Deceleration
Distance,
the
Height
of
the
Worker,
plus
a
Safety
Factor
of
1
1/2’.

4.4
Swing
Fall:
Swing
falls
occur
when
the
anchorage
point
is
not
directly
above
the
point
where
a
fall
occurs.
The
force
of
striking
an
object
in
a
swing
fall
may
cause
serious
injury.
In
a
swing
fall,
the
total
vertical
fall
distance
will
be
greater
than
if
the
user
had
fallen
directly
below
the
anchorage
point,
thus
increasing
the
total
free
fall
distance
and
the
area
required
to
safely
arrest
the
user.
An
SRD
presents
the
greatest
danger
in
a
swing
fall
event.
Minimize
swing
falls
by
working
as
directly
below
the
anchorage
point
as
possible.
Move
the
anchorage
as
required.
Never
permit
a
swing
fall
if
injury
could
occur.
If
a
swing
fall
situation
exists
in
your
application
consult
a
Competent
Person
before
proceeding.
A
minimum
of
six
feet
from
the
working
level
to
the
lower
level
or
nearest
obstruction
is
recommended.
See
Figure
5.
4.5
Captive
Pin
Installation:
Certain
model
carabiners
are
supplied
with
a
captive
pin,
that
when
installed
forms
a
captive
eye
for
connection
of
a
lanyard,
lifeline,
or
similar
component.
To
install
the
captive
pin,
drive
the
pin
into
the
predrilled
hole
in
the
gate
bar
until
the
formed
capture
portion
of
the
pin
engages
the
carabiner.
4.6
Carabiner
instructions:
Rotate
the
twist
lock
until
it
stops.
Push
the
gate
inward,
engage
the
carabiner
onto
the
selected
anchorage,
and
release
the
spring
‐
loaded
gate.
Visually
ensure
