Fall arrest accessories are essential components that help enhance safety and functionality while working at height. They include items like carabiners, anchorage connectors, rope grabs, and self-retracting lifelines. 

Carabiners are used to connect various components of the fall protection system, such as anchorage connectors, rope grabs, and lanyards. Anchorage connectors are used to provide a secure and safe attachment point for the fall arrest system. Rope grabs are used to attach the lanyard to the lifeline, and they move along the lifeline to provide the user with continuous fall protection. Self-retracting lifelines are designed to stop the user's fall instantly and are suitable for use in a variety of environments. 

Other fall arrest accessories include harnesses, work positioning belts, and rescue devices. Work positioning belts are used to support the user in a work position, while rescue devices are used to recover a worker in the event of a fall. All of these accessories play an important role in ensuring the safety of workers at height.
