E.2.1.1 Fall arrest systems (see Part 2, 2.7.1.5) should incorporate an energy dissipating element, component or feature to keep the impact load (more accurately, the deceleration) experienced by the user in a fall to an acceptable level. This varies from 4 kN to 8 kN, depending on the region, e.g. in the European Union it is currently a maximum of 6 kN, in Canada it varies between 4 kN and 6 kN, while in the USA, it is generally 6 kN but in some cases is allowed to reach 8 kN for a few milliseconds (ms). (This brief excursion to 8 kN is considered to be inconsequential.) The impact loads are kept below these maximums typically by the use of an energy absorber either integrated with or attached to the fall arrest lanyard that connects the user directly or indirectly to the structure or natural feature.
