The Fall Factor is determined in order to measure the impact force applied to the worker during a hypothetical fall and to add the free distance required to arrest the fall.
Therefore the fall factor calculation is based on the height of the anchor device in relation to the anchor point on the user's harness. We'll explain all this in the pictograms below.
When conducting a study to mount an anchorage point or lifeline, Elytra, first considers the position of this device in relation to the user who will be anchored to the system.
Once this point has been analysed, the next step is to check that there is sufficient free space available to arrest the fall.
This is why the fall factor is decisive.
When the fall is 0 times the distance connecting the worker to the anchor device.
If, as shown in the pictogram, the length of the connection to the anchor device is 1.5 metres, then the worker will fall this distance multipled by 0. There is no fall. This is the ideal situation for the worker, as the anchor device is overhead.
The worker is in a fall factor 1 situation when the fall is equivalent to the length of the connection to the anchor device..
The worker is in factor 1 when the anchor device is at the same height as the harness anchor point..
So that, as shown in the pictogram, the fall is 1M x 1M.
When the free fall is 2 times the distance connecting the worker to the anchor device.
This is the least favourable situation as far as the fall is concerned, as the free fall will be very high.
Normally this factor is considered when the anchor device is below the worker's feet.
The mounting of systems with the fall factor should be avoided.
