Abstract Dangerous vapours emanating from electroplating baths are generally eliminated by local exhaust systems. Practical studies showed that the volume of air to be exhausted can be considerably reduced by using 4-sided slot exhausts and lip exhausts, instead of double-sided slot exhausts of the ordinary type. 4-sided lip-type exhausts offer enough practical advantages and economy to compensate for their more sophisticated installation and the loss in bath surface. The studies carried out also confirmed that the visual method of evaluating the elimination of air pollutants by local exhaust is as efficient as the method which consists in carrying out chemical tests.
