Railings on roof near units within 6 feet of the edge need a railing which is at least how tall in inches?

Explanation:
The main idea is that guardrails protecting edges must meet a minimum height to effectively prevent falls. For railings on a roof edge when you’re within six feet of the edge, the required minimum height is 42 inches. That height provides a practical barrier without being so tall as to cause unnecessary obstruction. A shorter height, like 36 inches, wouldn’t meet the fall-protection standard, while taller options (48 or 60 inches) do satisfy the requirement but aren’t the minimum set by the code.
