There are three types of fall factor, the first of them is the fall factor < 1.In this situation, the fall displacement will be less than the lanyard size (1.30 m), thus generating an impact force supposedly incapable of opening the energy absorber and causing some type of injury to the worker. After this assessment, we can affirm that in the first two situations the safest thing to do is to respect the free-fall zone informed by the manufacturer.To perform a safe activity below 4.90 m we must always have in mind the ideal work condition (last situation) where your fall factor is < 1, because the fall displacement won’t be enough to open the energy absorber and we can disregard the lanyard size and the distance between the lanyard connection point in the Safety Harness and the user's foot in the calculation; thus, having to respect 1 m (safety height) and the size of the displacement provided by the resulting lanyard slack.
