STRUCTURAL DESIGN SAFETY FACTORS EX- CEED ANSI AND OSHA REQUIREMENTS on the GEMINI units. All metal structural components in the unit as they support the rated load are designed to provide a minimum safety factor of 3:1 on yield and a minimum ultimate safety factor of 5:1.Struc- tural fiberglass booms and platforms are designed at a minimum ultimate strength safety factor of 10:1.
