SECTION 2: Hazards identification

GHS Classification Optical glasses are physically and chemically stable and are not hazardous. However, the following danger hazardousness is concerned during processing of optical glasses. ： Ingestion of grinding and polishing liquids and inhalation of dust generated during dry processing may cause chronic or cumulative health impairment including cancer.

Environmental effects

Pay attention to the concentrations of grinding and polishing liquids in wastewater as they may damage the ecosystem.
