Abstract Sulfuric acid is widely used, in particular for treating metal surfaces. Workers in pickling workshops are exposed to sulfuric acid aerosols that have corrosive effects on the skin and the respiratory tract. In this study involving 156 pickling workshops, worker exposure was evaluated by means of ambient and breathing air sampling. Findings showed that most workshops were in compliance with threshold limit values. Measures aimed at limiting worker exposure to sulfuric acid (increase in ventilation flow, local exhaust) were proposed in several cases where MAK values were exceeded.
