Answer :

Final answer:

Guardrail or cover is necessary for floor openings measuring at least 12 inches to ensure safety and prevent falls.


Explanation:

Guardrail or cover is required for a floor opening that measures at least 12 inches in its least dimension to ensure safety and prevent falls. According to OSHA standards, employers must provide fall protection such as guardrails to protect workers from hazards. Warning signs alone are not sufficient to secure the opening.
