The 1840 Act prohibited any person under 21 being compelled or knowingly allowed to ascend or descend a chimney or flue for sweeping, cleaning or coring.[4] This Act ensured all chimney-sweeps would be registered with the police, and that official supervision of their work would take place.[5] The provisions of all previous acts would now take place.[6]
