What are the three main systems of fall protection?

The three main systems of fall protection include a guardrail system, personal fall arrest systems, and warning line systems. Each system has a specific function and is designed to prevent falls in different scenarios within the construction industry.

A guardrail system acts as a physical barrier that prevents workers from falling off elevated surfaces, such as roofs or scaffolding. It is made up of top rails, midrails, and toe boards, which are installed at specified heights and are essential for creating safe working environments.

Personal fall arrest systems are used to safely stop a worker who is in free fall. This system typically includes harnesses, lanyards, and anchorage points, which work together to minimize the risk of injury by absorbing the energy of the fall and preventing the worker from hitting the ground or other structures.

Warning line systems serve as a visual alert for workers approaching an unprotected edge. These lines are established around the area where work is being done at heights, notifying workers of potential fall hazards without providing physical barriers like guardrails.

The other options contain combinations of systems that either do not specifically serve the primary purpose of fall protection or introduce elements, such as training or inspection, that are important for safety but do not directly function as fall protection systems.
