What are the dangers of being a robin boy?

Children would work in factories as Bobbin boys. Their job was dangerous, basically the safety regulations of the textile Mills are nearly non existent. Small children are being left on massive factory floors that have multiple machines running and in close proximity to each other. The boy s job are to replace the broken threads and bobbins in these dangerous machines. To make things worse by sticking their hands in these running machines to fix a pin the boys had to balance on the basket like frame hanging off the machine.
