Quick Guide: Components of a Fall Arrest System
Ensuring the safety of workers at height is critical and fall arrest systems are key to preventing serious accidents. A complete system consists of several interconnected components, each playing a vital role in maintaining safety and efficiency. Honeywell and SPI have put together this guide to highlight the main components of a fall arrest system:
An anchor is a fundamental component of the fall arrest system. It must be securely attached to a structure capable of supporting a minimum load of 5,000 lbs (approximately 22 kN). Be sure to verify this requirement with your provincial or federal OHS regulations, as they may vary depending on your jurisdiction.
Anchor points can be either permanent or temporary and must be installed in compliance with applicable standards and regulations.
Anchor connectors link the other components of the fall arrest system to the anchor point. These can include various types such as cable or noose ties, carabiners, beam anchors, and D-rings. A wide range of models are available to suit different surfaces, including concrete and rooftops.
Anchor connectors must be strong and reliable to prevent accidental disconnection, ensuring maximum safety.
The safety harness is worn by the worker to distribute the forces of a fall across the body, particularly the thighs, pelvis, chest, and shoulders. For maximum comfort and safety, the harness must fit snugly. Most harnesses come with multiple attachment points to suit different applications.

Restraining links connect the worker to the anchor point and anchor connector. These links come in different forms, including safety lanyards, fall limiters, or retractable devices.
An energy absorber is designed to reduce the force of impact during a fall. It deploys upon a fall, creating a deceleration distance that minimizes the energy generated. This significantly reduces the impact transmitted to the worker's body, greatly lowering the risk of serious injury.
Safety lanyards can be made from textile materials like polyester or nylon, or from steel for added durability. They come in various lengths and hook configurations and can be either single or Y-shaped. To limit the stopping force during a fall, lanyards should be equipped with an energy absorber.
Self-retracting devices, such as fall arresters, provide maximum mobility while ensuring continuous fall protection. They automatically retract to maintain constant tension and lock instantly in the event of a fall. The built-in braking mechanism absorbs energy to minimize the risk of injury. Like safety lanyards, these devices come in various lengths and configurations to suit different needs.
Lifelines can be set up with horizontal or vertical cables, ropes, or even rigid rails, allowing workers to move freely while remaining securely attached. These systems can be temporary or permanent and must be installed and inspected regularly to comply with current regulations. Additionally, there are specialized systems for confined space entry and rescue, along with other engineered safety solutions.
