The Quarry Act, also known as the Mines and Quarries Act, was significant because it addressed critical safety and labor issues in mining and quarrying operations. Implemented in various forms and in different countries, such acts were primarily designed to provide better working conditions, reduce accidents, and protect workers' health. Key aspects often included regulations on ventilation, machinery maintenance, mine inspections, and working hours. By improving safety standards and oversight, the Quarry Act helped to prevent fatalities and serious injuries, thereby contributing to the overall welfare of workers in these hazardous industries.
