What is the purpose of a personal fall arrest system?

A personal fall arrest system is specifically designed to prevent workers from hitting the ground in case of a fall while working at heights. Its primary components generally include a harness, lanyard, and anchorage point, which work together to stop a person from falling and ensure that they remain safely suspended. This system not only stops a fall but also plays a crucial role in mitigating the risk of serious injury or fatality.

The primary goal of this safety equipment is to effectively “arrest” or stop a fall in progress, which is essential in construction, maintenance, and similar environments where workers face the risk of falling from elevated positions. This is why the option highlighting the purpose of the system as one that arrests a fall and protects the worker is the most accurate.

In contrast, options that suggest preventing slips on wet surfaces or enhancing visibility at heights address different aspects of safety but do not pertain to the function of personal fall arrest systems. The mention of providing cushioning during a fall misconstrues the system's purpose, as it is designed to stop rather than cushion a fall. The effectiveness of a personal fall arrest system lies in its ability to securely hold and protect the individual rather than merely providing comfort or visibility.
