Fall clearance is the vertical distance below the anchorage point to the first of
impact.
GENERAL CALCULATION
(FC)
Fall Clearance
(FFD)
Free Fall Distance
(SA)
Maximum length of extended
shock absorber
(WH)
Height of Worker
(SF)
Safety Factor
As per AS/NZS 1891.4 the
Fall Clearance (FC) can be
reduced by limiting the
free fall distance (FFD) and
reducing the amount of
shock absorber tear out (SA)
Fall Factor 0 indicates that you have reduced as much free fall distance as
possible by attaching your lanyard above.
Fall Factor 1 indicates your anchor point is at the same level as your attachment
point on the harness. This means that you will potentially fall the full length of
your lanyard (2m on a 2m lanyard).
Fall Factor 2 is the worst case scenario, where you are anchored at your feet.
This means you will fall up to twice the length of your lanyard. A total of 6.75m
clearance would be required when using a 2m lanyard.
