1.1

The excerpts provide information about guardrail heights. The top edge height of toprails or equivalent members on supported scaffolds manufactured or placed in service after January 1, 2000, shall be installed between 38 inches (0.97 m) and 45 inches (1.2 m) above the platform surface. For supported scaffolds manufactured and placed in service before January 1, 2000, and for all suspended scaffolds where both a guardrail and a personal fall arrest system are required, the height shall be between 36 inches (0.9 m) and 45 inches (1.2 m) [OSHA 3150 Scaffold Guide, Sec E, p.42].

1.2

The excerpts do not provide additional details on other potential minimum heights for guardrails outside of these specifications.
