A full body harness for working at height is a critical piece of personal protective equipment (PPE) used to protect workers from fall hazards in elevated work environments. Designed with high-strength webbing straps that secure the shoulders, chest, and legs, a full body harness distributes fall forces across the strongest parts of the body during a fall. This design significantly reduces the risk of serious injury compared to outdated body belts and ensures a safer connection to a complete fall protection system.
A modern full body safety harness is typically used together with a lanyard or self-retracting lifeline connected to a certified anchorage point. When properly fitted and used as part of a personal fall arrest system, the harness helps arrest a fall safely and keep the worker in an upright position, minimizing the risk of suspension trauma and other severe injuries.
Industries such as construction, telecommunications, utilities, oil & gas, and industrial maintenance rely on safety harnesses for working at height to maintain safe jobsite operations and comply with international safety standards. Choosing the right harness is essential for both worker protection and regulatory compliance.
At FPR Supply, we provide certified full body safety harnesses designed for professional working at height applications. Our products meet international safety standards and are trusted by contractors and industrial companies across Vietnam.
What Is a Full Body Harness for Working at Height?
A full body harness is essential PPE designed to protect workers from falls when working at height. It fits around the shoulders, chest, and legs to distribute impact forces safely across the body.
Used as part of a Personal Fall Arrest System (PFAS), the harness connects to self retracting lifeline or lanyards and a secure anchor point to stop falls quickly and reduce injury risk.
It is widely used in construction, maintenance, and industrial work, providing both safety and comfort through adjustable straps and multiple attachment points.

How a Full Body Harness Works in a Fall Protection System
A fall protection harness does not function independently — it is part of a complete personal fall arrest system (PFAS) designed to stop a fall safely and minimize the risk of injury. This system typically consists of three essential components: a secure anchorage point, a connecting device, and the full body harness itself. Each element plays a critical role in protecting workers who perform tasks at height.
Anchorage Point
The anchorage point is the secure structural attachment where the fall protection system is connected. It may be a certified anchor bolt, beam clamp, horizontal lifeline system, or a structural steel component capable of supporting the required load. A properly rated anchorage must withstand significant force in the event of a fall. Without a strong and compliant anchor, even the best fall protection harness system cannot provide adequate protection.
Connecting Device (Lanyard or SRL)
The connecting device links the worker’s harness to the anchorage point. This connection is typically made using a shock-absorbing lanyard or a self-retracting lifeline (SRL). A shock-absorbing lanyard is designed to extend slightly during a fall, reducing the impact force applied to the body. An SRL automatically retracts and locks when a sudden drop occurs, limiting free-fall distance and quickly arresting the fall. Both devices are essential components in maintaining the effectiveness of a personal fall arrest system.
Full Body Harness
The full body harness secures the worker and distributes fall forces across the strongest areas of the body, including the shoulders, chest, pelvis, and thighs. When connected to a fall protection system, the harness keeps the worker properly positioned and prevents them from slipping out during a fall. By spreading the impact forces across multiple points of the body, the harness significantly reduces the risk of severe injury and provides the necessary support for safe rescue if needed.

Main Components of a Full Body Harness
Understanding the key full body harness parts is important for proper use, inspection, and safety when working at height. A modern harness is designed with several integrated components that provide strength, stability, and comfort for the user. These full body harness details work together to secure the worker and distribute fall forces effectively during a fall.
Webbing Straps
Webbing straps form the main structure of the harness. Made from high-strength polyester or nylon, these straps wrap around the shoulders, chest, and legs to secure the user while distributing impact forces across major muscle groups.
D-Rings (Dorsal, Front, Side)
D-rings are the metal attachment points that connect the harness to a fall protection system.
Dorsal D-ring: Used for fall arrest systems.
Front (sternal) D-ring: Often used for ladder climbing or vertical lifelines.
Side D-rings: Designed for work positioning applications.
Buckles and Adjusters
Buckles allow users to fasten and adjust the harness for a secure and comfortable fit. Common types include tongue buckles, quick-connect buckles, and pass-through buckles.
