A pulley system would save manpower but manpower wasn't the limiting factor last night. It was buckets and throughput. Pulley system wouldn't work inside. There isn't a gap in the stairwells and it's not a straight shot up. Going over the side of the building would potentially work but there'd need to be a boom to get it off the side of the building and without some sort of power winch it's a matter of hauling one or two buckets up manually and I think that'd be lower throughput than the brigade system where you get 1-2 buckets in the time it takes to walk up two flights of stairs.
