What are unprotected sides and edges?

Unprotected sides and edges refer to work areas that lack any form of safety barriers or railings, creating fall hazards for workers. In the context of occupational safety, specifically under OSHA standards, these areas are considered high-risk zones where workers may be exposed to falls from elevated surfaces. Without guardrails or similar safety installations, there is an increased potential for accidents, which underscores the importance of implementing appropriate fall protection measures.

In contrast, areas on a roof with guardrails are protected from falls, while walking working surfaces that have walls or guardrails provide added safety and security to prevent accidental falls. Well-marked excavation sites may indicate a regulated area but do not inherently relate to the concept of unprotected edges. Therefore, the emphasis on the absence of safety measures in option C accurately captures the definition of unprotected sides and edges.
