2.6:
Fall
Restraint
Fall
Restraint
is
an
area
of
Fall
Protection
devoted
to
restraining
the
user
of
the
system
in
a
manner
which
restricts
his
or
her
access
to
the
fall
hazard
in
a
manner
such
that
they
cannot
be
subjected
to
a
fall.
A
typical
Fall
Restraint
System
consists
of
an
anchorage,
a
full
body
harness
or
a
restraint
belt
and
a
restraint
lanyard.
An
SRL
should
never
be
utilized
in
a
restraint
application
as
it
is
not
capable
of
restricting
a
user’s
access
to
fall
hazards.
2.7:
Work
Positioning
Work
Positioning
is
an
area
of
Fall
Protection
devoted
to
allowing
a
user
to
work
on
a
vertical
surface
by
means
of
a
positioning
assembly,
and
restricting
the
user’s
exposure
to
a
fall
of
no
more
than
two
feet.
Typical
positioning
assemblies
consist
of
a
large
rebar
hook
and
a
length
of
chain,
rope,
wire
rope
or
webbing
with
a
double
locking
snap
hook
on
either
end.
These
snap
hooks
are
attached
to
d
‐
rings
on
the
hips
or
on
the
waist
of
the
user’s
full
body
harness,
with
the
rebar
hook
attached
to
the
structure
upon
which
the
user
is
working.
An
SRL
should
never
be
used
for
work
positioning,
nor
should
it
ever
be
attached
to
a
side
or
hip
d
‐
ring
on
a
full
body
harness.
2.8:
Free
‐
Fall
Free
‐
Fall
is
the
distance
that
a
worker
will
fall
before
the
connecting
device
or
deceleration
device
elements
of
the
PFAS
will
begin
to
engage
during
a
fall
event.
OSHA
allows
a
maximum
Free
‐
Fall
Distance
of
6’
(6
feet)
when
rigging
a
Personal
Fall
Arrest
System
(PFAS).
In
some
cases,
exceptions
may
be
allowed
when
there
is
no
practical
way
to
limit
the
Free
‐
Fall
Distance
to
6’,
such
as
a
job
‐
site
where
no
overhead
anchor
‐
point
is
available.
Tying
off
in
a
manner
that
would
create
a
Free
‐
Fall
greater
than
6’
should
always
be
a
last
resort.
If
you
are
rigging
a
system
that
allows
more
than
6’
of
Free
‐
Fall,
make
sure
your
Connecting
Device/Deceleration
Device
is
rated
for
this
application.
FallTech
Web
SRL’s

NOT

2’!
2.9:
Clear
‐
Fall
Clear
‐
Fall
or
Clear
‐
Fall
Distance
is
the
distance
that
is
required
to
safely
arrest
the
fall
of
a
user.
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
that
the
components
selected
are
capable
of
arresting
the
user’s
fall
before
they
hit
the
next
lower
level.
The
required
Clear
‐
Fall
Distance
can
easily
be
calculated
by
adding
together
the
Free
‐
Fall
Distance,
the
Deceleration
Distance,
the
height
of
the
user
plus
a
safety
factor
of
2
feet.
The
formula
for
calculating
Clear
‐
Fall
Distance
is
shown
below:
