By March 2006, 101 cases of probable and definite work related respiratory disease had been identified among workers.
Among these, there were 87 cases of occupational asthma (OA) and 24 cases of extrinsic allergic alveolitis (EAA). Some workers were diagnosed with more than one disease. It is thought these represent the world’s largest recorded outbreak of
occupational respiratory disease linked to metalworking and wash fluids. This report outlines emerging lessons, which are for suppliers and users of metalworking and wash fluids, health professionals, and designers of metalworking and washing machines. There are also issues for occupational hygienists and health and safety regulators to consider.
