What kind of array marking do you all use? I’ve seen both paint and tape used to mark fissile storage arrays, but is anyone using something like a projector for array lines? Any thoughts on pros/cons for any of these options? ---

We use retractable belt barriers (like what you see for crowd line/organization). This allows operations some flexibility for arrays that might have a dynamic/changing size- for instance in areas that might normally have just a handful of drums but then regularly increase for incoming or outgoing shipments. ---

Interesting! Do you control the arrays by a max number of drums or is it by a max array dimension? Do you have different spacing requirements from arrays than with normal container/drum handling? That way the stanchions help identify what am array is and, if it has larger spacing requirements, that items need to be spaced further away from it?
