When sourcing fiberglass platform ladders, the most critical factor is the Load Capacity (Duty Rating). Ensure the ladder meets ANSI A14.5 (North America) or EN131 (Europe) standards. For industrial use, a Type IA (300 lbs) or Type IAA (375 lbs) rating is recommended. Additionally, verify the Non-Conductive properties of the fiberglass rails, which are essential for electrical work. The Platform Size should be at least 14 x 18 inches to provide a stable work surface, and the Handrail Height should be at least 2 feet above the platform for user safety.
