Understanding the Difference Between a Horizontal and a Vertical Fall Arrest System

According to the Bureau of Workplace Safety, falls are consistently among the leading causes of workplace injuries that lead to days away from work. The latest available report (2020) showed that over 49,000 workers were injured due to falls to a lower level. 

Fall arrest systems are pivotal in safeguarding workers to mitigate these risks. Among the array of fall arrest systems available, two prominent categories stand out: horizontal and vertical fall arrest systems. 

This comprehensive guide will delve into the crucial differences between these two systems, their significance, and the circumstances under which each is optimally employed.

The Need for Fall Arrest Systems

Need for Fall Arrest Systems


The Occupational Safety and Health Administration (OSHA) reinforces the responsibility of employers to provide their employees with safety equipment appropriate to their work environment. One such equipment is the fall arrest system.

Fall arrest systems are engineered to absorb the energy generated during a fall and gradually bring the falling person to a stop, preventing them from hitting the ground or other surfaces with lethal force. By providing adequate protection, fall arrest systems ensure workers can carry out their tasks at elevated positions without compromising safety.

Horizontal Fall Arrest Systems: Crossing the Safety Horizon

Horizontal fall arrest systems are designed to protect workers moving along a horizontal plane, such as on rooftops, bridges, or suspended platforms. These systems consist of components, including anchor points, lifelines, connectors, and harnesses. 

The lifeline, usually made of high-strength materials like steel cable or synthetic fibers, spans the work area, allowing workers to attach their harnesses and move freely. If a fall occurs, the system's energy-absorbing mechanisms kick into action, dissipating the force of the fall and preventing a sudden jolt to the body.

Vertical Fall Arrest Systems: Safeguarding Ascent and Descent

In scenarios where work tasks involve ascending or descending vertical surfaces like ladders, towers, or confined spaces, vertical fall arrest systems come into play. These systems incorporate ladder safety systems, vertical lifelines, and self-retracting lifelines. 

A vertical lifeline typically consists of a cable running alongside the climbing structure, while a self-retracting lifeline allows users to move vertically while keeping the lifeline taut. These systems activate in the event of a fall, arresting the fall and preventing a disastrous impact.

Choosing the Right System for the Right Job

Determining whether to use a horizontal or vertical fall arrest system hinges on the specific task at hand and the environment in which it is performed. Here's a simplified breakdown of when each type is most suitable:

Use a horizontal fall arrest system when:

  • The work requires movement along a horizontal plane, such as roofing, bridge maintenance, or suspended platform tasks
  • There is a need for freedom of movement across large areas, such as when workers need to access different points.

A horizontal fall arrest system requires the proper installation of anchor points. Consider that your workers need adequate training to properly attach and detach from the lifeline.

Use vertical fall arrest equipment when:

  • The tasks involve climbing up or down vertical surfaces, such as towers, buildings, lifts, and walls
  • You need a more compact, streamlined fall arrest system suitable for confined spaces

Consider the user's ability to connect to the system properly. The system may restrict lateral movement, unlike horizontal systems.
