[Diseases caused by cooling lubricants in the metal-processing industry. Suggestions for solving a multifactorial occurrence].

It is shown that diseases caused by soluble oil emulsions concern multiple actions with chronic processes. Recrudescences occur during these processes, demonstrated by monocausal formation. Neutralisation of all factors which alone or combined induce skin damage appears unrealistic. Solving the problem in the long run does not mean neutralising the soluble oil emulsions and other skin-damaging factors in question, but removing their influence using mechanisation instead. Until mechanisation is realised other primary and secondary measures are necessary, particularly selection.
