What is the required safety factor for wire rope slings and rigging when using a man basket?

The required safety factor for wire rope slings and rigging when using a man basket is established at five times the maximum intended load. This standard is grounded in ensuring maximum safety for workers being lifted, as it accounts for the unpredictable nature of dynamic loads, potential wear and tear on the equipment, and other factors that could compromise the integrity of the rigging. A safety factor of five provides a significant margin for error and risk mitigation, ensuring that even in the most challenging scenarios, the rigging system remains capable of supporting the weight safely.

Options that present lower safety factors, such as three or four times the maximum intended load, do not offer adequate protection against failures or unforeseen circumstances. A safety factor of six, while it may seem prudent, is not typically required and could lead to unnecessary costs in materials and rigging while not enhancing safety to a meaningful degree. The five times safety factor strikes a balance between effectiveness, cost, and safety regulations, making it the standard practice in the industry.
