Trapper

A child employed underground to open and close the wooden ventilation doors that controlled a mine's airflow, letting wagons and hurriers pass before closing again behind them.

Historical usage

Children as young as five or six worked as trappers, typically the first and lightest underground job given to a mining family's youngest children before they were old enough to become hurriers, pushing and pulling loaded tubs. The role, and the conditions attached to it, were documented in detail by the Royal Commission of Inquiry into Children's Employment, set up under Lord Ashley (later the Earl of Shaftesbury) in 1840; its 1842 report, illustrated with engravings and first-hand testimony from mine workers, shocked Victorian public opinion and led directly to the passing of the Mines and Collieries Act 1842.

How it worked

A trapper sat alone beside their door, often in total darkness, for shifts of up to twelve hours, opening it only when a tub or hurrier needed to pass through and closing it again immediately afterward to keep the mine's ventilation circuit intact.

Why it was used

A mine's ventilation depended on doors being opened and shut promptly and only when needed, a task considered simple enough — if isolating and tedious — to assign to the youngest children in an underground workforce, while freeing older, stronger children and adults for haulage and coal-getting.

Risks & limitations

Long solitary hours in darkness, and the physical and developmental toll of full-time underground child labour more broadly, were central to the case the 1842 Royal Commission made to Parliament; the Mines and Collieries Act that followed banned underground work altogether for women and girls, and set a minimum age of ten for boys.
