What are active fall protection systems?

Active fall protection systems are devices that require worker engagement for their effective use, such as harnesses and lanyards. These systems are designed to actively protect workers from falling while they are at heights. The user must wear a harness that is connected to a lanyard, which in turn is anchored to a secure point. This engagement is crucial, as the effectiveness of these systems depends on proper usage and adherence to safety protocols.

The other options do not accurately represent what constitutes active fall protection. Systems that require no worker engagement would fall under passive protections, which help prevent falls without requiring interaction. Devices limited to stationary equipment would not encompass the broader application of active systems used in various work environments. Finally, environmental safety measures do not typically involve direct fall protection for individuals working at height and focus instead on factors such as site conditions or hazards that can impact workers.
