Foundry Environment Health & Dust Problem in Foundries topics include: Foundry environment health and safety, dust measurement, dust control, foundry dust extraction and dust collecting equipment. Foundries have many health hazards, including: Dust: Foundries have large amounts of fine respirable dust that contains silica. Fumes: Fumes from zinc and copper can cause metal fume fever. Fumes and dust from cadmium, beryllium, nickel, and chromium are toxic. Other materials: Foundries also have silica sand, chromium, carbon monoxide, carbon, iron oxide, and fluorides.  Other health risks... Show more
