ページを印刷するFree Fall
To calculate the free fall distance using an Energy Absorbing Lanyard connected to the dorsal
D-ring of a full body harness and an anchorage connector that is above the workers shoulders,
Worker (a), subtract the distance from the D-ring on the harness to the anchorage connector (5
ft) from the length of the Energy Absorbing Lanyard (6 ft). The free fall for Worker (a) is 1 ft.
The free fall distance with an Energy Absorbing Lanyard connected to the dorsal D-ring of a full
body harness to an anchorage connector that is at the workers shoulders, Worker (b), is equal to
the length of the lanyard. The free fall for Worker (b) is 6 ft.
To calculate the free fall distance using an Energy Absorbing Lanyard connected to the dorsal
D-ring of a full body harness to an anchorage connector that is below the workers shoulders,
Worker (c), add the distance from D-ring on the harness to the anchorage connector (5 ft), to the
length to the of the Energy Absorbing Lanyard (6 ft). The free fall for worker (c) is 11 ft.
Swing Falls
To minimize the possibility of a swing fall, work as directly under the anchorage connector as
possible. Striking objects horizontally, due to the pendulum affect, may cause serious injury.
Swing falls also increase the vertical fall distance of a worker, compared to a fall directly below
the anchorage connector. Swing falls may be reduced by using overhead anchorage connectors
that move with the worker.
