What does a Full Body Harness Fall Arrest System Do?
A full body harness fall arrest system is a vital piece of personal protective equipment (PPE) used to prevent serious injury or fatalities in the event of a fall from height. But what exactly does it do?
What is a Full Body Harness Fall Arrest System?
A full body harness fall arrest system is a combination of a body harness, a lanyard, and a connector that works together to catch and decelerate the user in the event of a fall. The system is designed to reduce the impact of a fall to the user, preventing injuries and fatalities.
Key Components of a Full Body Harness Fall Arrest System
A full body harness fall arrest system typically consists of the following key components:
- Body Harness: A body harness is the main component of the fall arrest system. It is a padded vest that is designed to distribute the force of a fall across the chest, pelvis, and thighs. The harness is typically made of durable materials such as nylon or polyester.
- Lanyard: A lanyard is a length of rope or webbing that connects the body harness to the anchor point. It is designed to absorb the shock of a fall and distribute the force across the user’s body.
- Connector: A connector is a device that connects the lanyard to the anchor point. It is designed to ensure a secure connection and prevent the lanyard from breaking or becoming detached during a fall.
How Does a Full Body Harness Fall Arrest System Work?
When a user is connected to an anchor point via a full body harness fall arrest system, they are essentially attached to the system by a lanyard. In the event of a fall, the following sequence of events occurs:
- Fall Initiation: The user falls from the anchor point.
- Lanyard Extension: The lanyard extends to a predetermined length, absorbing the shock of the fall.
- Connector Attachment: The connector attaches to the anchor point, stopping the user’s fall.
- Deceleration: The system slows down the user’s fall, reducing the impact on their body.
Benefits of a Full Body Harness Fall Arrest System
Using a full body harness fall arrest system provides numerous benefits, including:
- Reduced Risk of Injury or Fatality: A full body harness fall arrest system significantly reduces the risk of injury or fatality in the event of a fall.
- Improved User Protection: The system provides a high level of protection for the user, preventing serious injuries and fatalities.
- Increased Confidence: Knowing that they are equipped with a full body harness fall arrest system, users can work with increased confidence and focus on their task.
- Compliance with Regulations: Many jurisdictions require the use of fall arrest systems on construction and industrial sites, making the use of a full body harness fall arrest system a regulatory requirement.

Types of Full Body Harness Fall Arrest Systems
There are several types of full body harness fall arrest systems available, including:
- Rigid Lanyard Systems: These systems use a rigid lanyard that does not stretch during a fall.
- Stretch Lanyard Systems: These systems use a stretch lanyard that absorbs the shock of a fall.
- Rope Lanyard Systems: These systems use a rope lanyard that provides additional protection in the event of a fall.
- Self-Retracting Lanyard Systems: These systems use a self-retracting lanyard that automatically retracts the lanyard after a fall.
Conclusion
A full body harness fall arrest system is a critical piece of PPE that provides a high level of protection for workers in the event of a fall. By understanding the key components, benefits, and types of full body harness fall arrest systems, users can make informed decisions about their safety and protection.
