FALL FACTOR

Fall factor is a rating used to evaluate the danger of specific scenarios when working at heights.Fall Factor is calculated using  the following equation:

Fall Factor=Height of Fall/Length of Lanyard

In cases when the Fall Factor is 0 (e.g.the worker is positioned under the anchor point with a tensioned lanyard) or in cases when the Fall Factor is 1 or less and the freedom of movement is limited to 0.6m or less,positioning equipment is adequate.

Fall arrest equipment must be used for other situations where the Fall Factor is greater than 1 or more freedom of movement is required.

Systems involving Fall Factors include:

Restraint: technique used to prevent a worker from entering a fall risk area (e.g. positioning harness and lanyard EN358).

Positioning: technique used to position a worker securely in a fall risk area without creating a Fall Factor scenary(e.g.hanging beneath an anchor point in a positioning harness on a tensioned lanyard EN358).

Fall Arrest: technique used to catch and reduce the force of a fall from heights(e.g.use of a Fall Arrest Lanyard EN361 and Shock Absorbing Lanyard EN355).
