Abstract Methods (enclosure, local exhaust ventilation by hoods or slots) for removal of harmful gases and vapours from the acid baths are discussed. Slot extraction in the most common. Changes in process variables, e.g. reduction of temperature or concentration, addition of wetting agents or inhibitors, were studied; addition of wetting agents to sulfuric acid baths reduced acid mists by 95%. Recommendations for the required air volume to be removed from different baths are given, along with design variables. Instructions for controlling ventilation equipment, measuring pollutant concentration, chemical storage and handling, and preparation of safety sheets for the substances are included.
