Lanyard energy absorbers (including stretch-type energy absorbers) reduce the ensuing force in the case of a fall. A lanyard energy absorber consists of several layers of tape sewn on top of each other. In the case of a fall, the layers are stretched apart, thus reducing the ensuing force to maximum 6kN. When implementing a retention or arresting system, it is crucial to take this stretch into consideration. Most connectors are equipped with an integrated energy absorber.
Lanyard energy absorbers are tested and certified in accordance with EN 355. According to DGUV rule 112-198, as these lanyard energy absorbers are part of an individual's personal fall protection kit (PPE), they always need to be visually inspected prior to usage. In addition, it is a legal requirement to have the complete kit (including the energy absorber) inspected by a suitably qualified PPE specialist at least once a year to ensure it is in perfect working order.
