Shock Absorbing and Dissipating Systems: The 6 kN Limit in Working at Height<\/strong><\/h1>\n

What Are Shock Absorbing \/ Dissipating Systems?<\/strong><\/h2>\n

Shock absorbing<\/b> systems are extremely important in terms of enabling employees to work safely in healthy workspaces during working at height activities. Systems featuring shock absorbing<\/b> properties\u2014such as shock absorbing lanyards certified to EN 355, horizontal lifelines certified to EN 795:2012 TYPE C and TS 16415:2013 TYPE C, vertical lifelines certified to EN 353-1: 2021+A1:2017, and retractable fall arresters certified to EN 360\u2014absorb and dissipate the energy generated during a fall, ensuring that the impact force acting on the human body remains below 6 kN<\/b>.<\/p>\n

Do not forget to get advice from ARGA SAFETY<\/b> working at height system experts for the correct selection of shock absorbing<\/b> systems suitable for your work area.<\/p>\n

Technical Specifications of Double-Arm Shock Absorbing Lanyards<\/h2>\n

A shock absorbing<\/b> double-arm lanyard must be tested and certified in accordance with the EN 355 standard. Additionally, it must possess sharp edge protection features when used according to the RfU 11.074 EC standard.<\/p>\n

The primary duty of shock absorbing<\/b> double-arm lanyards is to arrest falls and to ensure that the impact force acting on the body of the personnel working at height remains below 6 kN<\/b>. Having a double-arm structure on the shock absorbing<\/b> lanyard prevents safety gaps by ensuring the user remains continuously connected to an anchorage point. Consequently, working safely while being continuously connected to anchorage points also increases the quality of the work performed. For example, a maintenance technician remains continuously connected to anchorage points during installation, maintenance, or repair works at height. It is obvious that the quality of installation, maintenance, or repair will be much higher when the fear of falling is eliminated.<\/p>\n

\n

Use of Double-Arm Shock Absorbing Lanyards<\/h2>\n

Shock absorbing<\/b> double-arm lanyards are used to transition between anchorage points during horizontal and vertical works. During operation, they should be positioned, as much as possible, above shoulder level and within arm’s reach. It may be necessary to reposition while performing horizontal or vertical works with shock absorbing<\/b> double-arm lanyards. Before starting to reposition, one of the lanyard arms is first attached to the target anchorage point in the transition area. Once the transition is made, the other lanyard arm is moved to the new anchorage point at the transition location.<\/p>\n

We frequently observe that workers use only one of the arms of a shock absorbing<\/b> double-arm lanyard. In this case, when a transition is needed, the user will not be connected to any anchorage points. Therefore, facing a vital danger in the event of a possible fall is inevitable.<\/p>\n

During the use of a single arm, the other arm is usually attached to the D-rings on the safety harnesses. Instead of this incorrect practice, it is correct to attach it to the plastic lanyard parking connectors<\/b> that must be present on the safety harnesses. In the event of a fall, the plastic lanyard parking connectors break away, allowing the carabiner to release. This prevents any obstruction to the deployment of the dissipating<\/b> unit during a fall.<\/p>\n

ZUMA Double-Arm Shock Absorbing Lanyards<\/b><\/h2>\n

The ZUMA<\/b> model Shock Absorbing<\/b> Lanyard by ARGA SAFETY<\/b> is manufactured and certified in accordance with the EN 355 standard. The lanyard provides a safe working area when used in combination with a Fall Arrest and Work Positioning Harness. The shock absorbing<\/b> double-leg lanyard ensures secure connection of the harnesses to all kinds of anchorage points. Thanks to its double-arm design, it guarantees that the worker is continuously connected to anchorage points.<\/p>\n
