Which of the following is not included in personal fall protection equipment and systems?

Guardrails are not considered part of personal fall protection equipment and systems because they are classified as a form of collective protection rather than individual protective measures. Personal fall protection equipment, such as harnesses, lanyards, and safety nets, is designed to protect the individual worker from falling when working at heights.

Harnesses are worn by workers to distribute the force of a fall over the body. Lanyards connect the harness to an anchor point, allowing for controlled movement while preventing falls. Safety nets serve as a collective system to catch individuals in the event of a fall, but they do not directly engage with the individual worker like harnesses and lanyards do.

In contrast, guardrails act as a perimeter barrier to prevent falls from elevated surfaces, making them part of site safety measures rather than an individual fall protection system. This distinction is important in ensuring that safety protocols are appropriate and effective for protecting workers in different scenarios.
