Workplace safety grew from mine fumes to global law
Occupational safety and health guards workers—and the public affected by workplaces—through medicine, hygiene, and promotion. United Nations estimates put annual work-related deaths near two million, with another 374 million non-fatal injuries. Long working hours now rank as the leading occupational disease burden worldwide.
OSH is multidisciplinary, aligning with occupational medicine and hygiene while protecting anyone touched by work environments. Employers in common-law systems owe a duty of care; statutes add specific duties and regulators. Prevention runs through company programs. The 1950 Joint ILO/WHO definition aims at highest physical, mental, and social well-being, preventing health departures, protecting against adverse factors, and adapting work to human capability—a 1995 consensus added promotion of working capacity, safer environments, and health-supporting organizational culture.
Written accounts of occupational disease date to the fifteenth century, when Ulrich Ellenbog warned metal workers about coal and mercury fumes and Paracelsus described miners' lung sickness; Georgius Agricola noted dust that eats lungs. Bernardino Ramazzini's 1713 Dissertation on Workers' Diseases catalogued hazards across fifty trades. Percivall Pott linked chimney sweeps to the first recognized occupational cancer. Britain's 1802 Health and Morals of Apprentices Act required lime-washed mills and ventilation for cotton apprentices—the first Factory Act. The 1833 Factory Act created inspectors; an 1842 royal commission on mining led to mine inspectorates; 1844 legislation added machinery guarding for women and children in textiles.
Bismarck launched Western social insurance and workers' compensation in the 1880s. The US Marine Hospital Service of 1798 evolved into the Public Health Service; New York passed compensation laws by 1910, later covering occupational disease. The 1911 Triangle Shirtwaist fire killed 146 mostly immigrant women behind locked exits amid radium cancers, phossy jaw, and silicosis epidemics. The 1969 Coal Mine Act and 1970 Occupational Safety and Health Act established OSHA and NIOSH. A landmark WHO/ILO study attributed an estimated 745,000 ischemic heart disease and stroke deaths in 2016 to long working hours—the largest single occupational risk factor globally.
