Blog1: Caisafety.com Fall Arrest Systems – Understanding The ABCD Behind Them The science of fall arrest systems was developed to provide a much needed layer of protection to personnel who have to perform their responsibilities and execute work in dangerous settings. They mainly cover scenarios where workers have to perform duties at a height, falling from which might cause a serious injury or prove to be fatal for them. This blog post will attempt to understand the science behind the equipment and technology developed to cater to these functions. For people looking to buy any type of fall arrest system, there are always four elements that must be considered. These elements make up the entire function of preventing a fall and saving the worker from resulting injury. They are often referred to as the ABCD of fall arrest, namely: A = Anchorage, this is a fixed structure that the rest of the equipment must be fixed to using anchorage equipment. B = Body Wear, The worker must wear a full body harness which is in turn attached to the rest of the system. C = Connector, is a component like a lanyard that is used to connect the anchorage to the harness. D = Declaration Device, this is a subsystem component that helps to dissipate the forces that are associated to a fall event These four components come together to create the fall arrest system that will effectively prevent the wearer from hitting the ground, in case he/she falls from a height. They are also designed to minimise impact of the fall and ensure that minimum injury and whiplash is generated as a result of an accident.
