絡電鍍作業之危害

電鍍作業系將特定金屬電鍍於被鍍件之表面，以達到特定的用途包括防腐蝕、防撞擊、增加光亮度及耐磨察等，為使被鍍體有良好的電鍍效果，在其製程必需事前經過各種前處理步驟，並添許多界面活性劑來增加導電度或電流強度。其中以鉻電鍍作業之危害性最大，台灣地區曾報告有關電鍍工廠環境暴露評估及勞工健康之調查結果，得知勞工有較高鼻中膈、肺功能及腎功能之異常率，同時亦發現其在染色體交換頻率有增加現象。因此，政府機關及電鍍業者應積極改善電鍍作業環境，研擬各種有效降低鉻酸逸散之方法包括加蓋、局部排氣裝置，加霧滴抑劑或採取半自動化作業等，以降低空氣中鉻酸濃度及有效保護作業勞工之身心健康。

The main purpose of electroplating manufacturing is to coat specific kinds of metals in order to protect from erosion, friction or breaking. Efficiency of Efficiency of electroplating is maintained by several pretreatment processes which includes adding surfactants to increase conductivity. Chromium is one of the most hazardous materials used in the electroplating process. Numerous studies have been conducted in Taiwan investigating the relationship between exposure to chromium and the workers´ health status. A high prevalence of disorders including nasal septum and dermal, lung, and kidney functions has been found. A high frequency of sister-chromated exchanges have also been discovered. These abnormalities represent a hazardous working environment for chromium electroplating workers. Several measures need to be adopted in order to decrease airborne chromium concentrations, including: installation of local ventilation systems, covering the electroplating tank and adding anti-foaming agents to prevent release of chromic acids, and to replace certain manual operations with semi-automation. Adoption of these measures and periodic governmental oversight are necessary steps toward creating a safe working environment for chromium electroplating workers.
