Abstract Hard metals, essentially based on tungsten carbide (CW) and cobalt (Co), are generally produced using powder metallurgy processes such as hot isostatic pressing, more rarely by melting. Many groups of subjects are exposed to these metals during their production, machining, welding and brazing. Co alone can cause immunoallergies such as asthma or non-respiratory impairments; when linked to CW, sometimes together with other metal carbides, it can cause pulmonary fibrosis and bronchopulmonary cancers. Contents of this review article on respiratory diseases caused by exposure to hard metal dust: hard metal production processes; metabolism and monitoring of occupational exposure; pathological effects on the human organism; collective prevention measures; medical supervision; current procedures for obtaining occupational disease compensation in France.
