Under what conditions is it safe to stand on a suspended load?

Is rigging considered a suspended load?
As stated in that letter, “The OSHA standard on overhead and gantry cranes, §1910.179, defines a load as ‘The total superimposed weight on the load block or hook. ‘ Since below the hook devices or slings would be part of the weight on the load block or hook, these would be considered a suspended load.”
