1. Harness and lanyard system: This is the most common type of fall arrest system and consists of a full-body harness worn by the worker, connected to a lanyard that is attached to an anchor point. The harness distributes the force of a fall across the body, while the lanyard absorbs the energy of the fall. Limitations include the potential for swing falls and the need for a suitable anchor point.
2. Self-retracting lifeline (SRL): An SRL is a device that automatically locks and arrests a fall when the worker moves away from the anchor point. It allows for greater mobility and reduces the risk of a swing fall. However, SRLs can be more expensive and may require more frequent inspection and maintenance.
3. Safety net: Safety nets are typically installed below a work area to catch a worker in the event of a fall. They are effective at reducing the risk of injury, but may not be suitable for all types of work environments and can be difficult to install and maintain.
4. Guardrail system: Guardrails are physical barriers that prevent workers from falling off elevated surfaces. They are a passive form of fall protection and do not require any action from the worker. However, guardrails may not be suitable for all work environments and may obstruct access to certain areas.
5. Suspension trauma relief straps: These straps are attached to the harness and allow a worker to relieve pressure on the legs during a fall arrest event. They can help prevent suspension trauma, which can occur when a worker is left hanging in a harness for an extended period of time.
Each type of fall arrest system has its own features and limitations, and the choice of system will depend on the specific work environment and tasks being performed. It is important to carefully assess the risks and requirements of the job to determine the most appropriate fall arrest system to use.
