What are the key elements of fall protection according to OSHA?

The key elements of fall protection according to OSHA are crucial components designed to prevent falls in construction and other industries where workers are exposed to height-related risks. The correct answer highlights specific fall protection systems: guardrails, safety nets, and personal fall arrest systems.

Guardrails are physical barriers installed at elevated work sites to prevent workers from falling off edges, while safety nets provide a safety buffer that catches workers who may fall. Personal fall arrest systems, which include harnesses and lanyards, are designed to securely attach a worker to an anchorage point to stop a fall and reduce the risk of injury upon descent. These systems collectively form a comprehensive approach to protect workers from fall hazards, adhering to OSHA regulations aimed at ensuring safety in the workplace.

In contrast, the other options refer to equipment or training not specifically categorized as fall protection systems under OSHA standards, which highlights the importance of understanding the distinct elements that are designated for fall prevention and safety in construction.
