Inhalation of finest aluminum oxide powders can cause inflammation in the lung.

 

Permanent exposure to aluminum oxides can cause damage to the lung. The related disease is referred to as aluminosis and is characterised by pathological changes of the lung that can be caused by chronic exposure to aluminum fumes or dusts, i.e. aluminum oxide particles from the aluminum oxide film that forms as the pure aluminum oxidizes immediately upon contact with air. Aluminosis belongs to the group of pneumoconioses and is an occupational disease subject to compensation.

Workers in the aluminum powder industry or welders in the automobile industry are required to wear suitable breathing protection. Dust formation during aluminum powder filling/refilling should be avoided and optimum ventilation/extraction by suction should be provided. The maximum admissible concentration (MAK value) of aluminum oxides must not exceed 1,5 mg/m3 (respirable fraction).
