Fall Factor is a rating used to evaluate the danger of specific scenarios when working at heights. Fall Factor (fig.6) is calculated using the following equation:
Fall Factor = Height of Fall / Length of Lanyard
In situations where the Fall Factor will be 0 (e.g. the worker is positioned under the anchor point on a tensioned lanyard) or in situations where the Fall Factor is 1 or less and the freedom of movement is limited to 0.6 m or less, positioning equipment is adequate (i.e. EN 354 – EN 358). Fall arrest equipment including an energy absorption feature (i.e. EN 355) must be used for any other situations where the Fall Factor is greater than 1 or more freedom of movement is required.
