According to OSHA regulations, a multi-part bridle is rated based on how many of its legs?

The correct answer, which indicates that a multi-part bridle is rated based on three of its legs, aligns with OSHA regulations regarding the load capacity and rating of such rigging configurations. When using a multi-part bridle, the design typically allows for multiple legs to share the load. However, when assessing the bridle's overall rating, it is crucial to consider the three most effective legs that contribute to the load distribution, as they bear the majority of the load during lifting operations.

This approach ensures that the rigging remains compliant with safety standards, taking into account the practical realities of load distribution and providing adequate safety margins. By focusing on these three legs, users can better understand the limitations and capabilities of their rigging setup, ensuring that it is appropriately rated for the intended lift.

Understanding this concept helps riggers select the right equipment for different lifting tasks, anticipate potential issues related to uneven load distribution, and maintain compliance with safety regulations, thereby enhancing overall workplace safety.
