Child Labor in the Industrial Revolution History Crunch

Spinning machines in textile mills were often left unguarded and posed a serious risk. For instance, a report from the British House of Commons in 1832 commented that “There are factories, no means few in number, nor confined to the smaller mills, in which serious accidents are continually occurring, and in which, notwithstanding, dangerous parts of the machinery are allowed to remain
