What is the primary function of fall arrest systems on structures?

The primary function of fall arrest systems on structures is to provide safety while working at heights. These systems are designed to stop a worker's fall within a certain distance and prevent injuries by using equipment such as harnesses, lanyards, and anchor points. They play a vital role in ensuring that workers can perform their tasks safely, minimizing the risk of falls that can lead to serious injuries or fatalities.

While minimizing equipment loss, enhancing team communication, and reducing project completion time are important aspects of construction and maintenance work, they do not represent the main purpose of fall arrest systems. These systems are specifically tailored to address the unique hazards associated with working at elevated heights, making worker safety the top priority.
