For silicon wafer plants, fine fumes from the furnaces and laser cutting process must be extracted to protect workers and machines from the super fine dust that they emit. With the cadmium glass process, much more attention is needed due to the toxic nature of cadmium. Containment features such as
Bag-In Bag-Out (BIBO) filter access and dust discharge removal are recommened. Also recommended are HEPA secondary filters to meet very stringent EPA laws which are at or below 0.0004 grains per cu ft (1 mg/cu meter).
