Manganese exposure may lead to various hazardous conditions due to chronic exposure. Manganese (Mn) is a strong, gray metal often used in steel manufacturing. Employees who are exposed to manganese through the inhalation of manganese dust or fumes might be affected. Prolonged exposure may cause kidney, liver, and lung damage. Exposure to manganese fumes or dust may also cause manganism, a neurological disorder. The duration, dosage, and kind of job performed determine the degree of exposure.
Furthermore, those most at risk of manganese exposure usually do welding operations. Welding is used in agriculture, mining, transportation, manufacturing, construction, and other vocations like millwright and pipefitter. Employees in the metallurgical and other industrial sectors are also in danger, although in somewhat lesser numbers.
