Unguarded machinery was a major problem for children working in factories. One hospital reported that every year it treated nearly a thousand people for wounds and mutilations caused by machines in factories. Michael Ward, a doctor working in Manchester told a parliamentary committee in 1819: "When I was a surgeon in the infirmary, accidents were very often admitted to the infirmary, through the children's hands and arms having being caught in the machinery; in many instances the muscles, and the skin is stripped down to the bone, and in some instances a finger or two might be lost. Last summer I visited Lever Street School. The number of children at that time in the school, who were employed in factories, was 106. The number of children who had received injuries from the machinery amounted to very nearly one half. There were forty-seven injured in this way."
Abraham Whitehead was a cloth merchant from Holmfirth who joined the campaign for factory legislation. He was concerned about the impact the work was having on the children. He told a parliamentary committee in 1832: "I have seen a little boy, only this winter, who works in the mill, and who lives within two hundred or three hundred yards of my own door; he is not yet six years old, and I have seen him, when he had a few coppers in his pocket, go to a beer shop, call for a glass of ale, and drink as boldly as any full-grown man, cursing and swearing." He believed that the tiredness of the children often caused accidents.
Robert Blincoe saw several accidents while working in the textile industry: "A girl named Mary Richards, who was thought remarkably handsome when she left the workhouse, and, who was not quite ten years of age, attended a drawing frame, below which, and about a foot from the floor, was a horizontal shaft, by which the frames above were turned. It happened one evening, when her apron was caught by the shaft. In an instant the poor girl was drawn by an irresistible force and dashed on the floor. She uttered the most heart-rending shrieks! Blincoe ran towards her, an agonized and helpless beholder of a scene of horror. He saw her whirled round and round with the shaft - he heard the bones of her arms, legs, thighs, etc. successively snap asunder, crushed, seemingly, to atoms, as the machinery whirled her round, and drew tighter and tighter her body within the works, her blood was scattered over the frame and streamed upon the floor, her head appeared dashed to pieces - at last, her mangled body was jammed in so fast, between the shafts and the floor, that the water being low and the wheels off the gear, it stopped the main shaft. When she was extricated, every bone was found broken - her head dreadfully crushed. She was carried off quite lifeless."
John Allett reported: "I have known more accidents at the beginning of the day than at the later part. I was an eye-witness of one. A child was working wool, that is, to prepare the wool for the machine; but the strap caught him, as he was hardly awake, and it carried him into the machinery; and we found one limb in one place, one in another, and he was cut to bits; his whole body went in, and was mangled." In 1842 a German visitor noted that he had seen so many people in the streets of Manchester without arms and legs that it was like "living in the midst of the army just returned from a campaign."
A report commissioned by the House of Commons in 1832 said 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 unfenced." The report added that he workers were often "abandoned from the moment that an accident occurs; their wages are stopped, no medical attendance is provided, and whatever the extent of the injury, no compensation is afforded."
