We have our flyperson do the weight call to the loaders and a "master of the deck" call from the stage to the flyperson. MOD keeps a visual along the line set on stage as it's moving. During a performance, the ASM or a carpentry deck crew member does the same visual observation so there is always someone watching when any piece is moving. I'm glad you included the repetition of the confirmation of the instruction. That helps prevent misunderstandings.

A 12.5kg brick falling from 22m is able to bounce at least 6m on a concrete/epoxy floor. Fun.
