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. ： When dust inhales during dry processing and melting, may cause chronic or cumulative health impairment.　And gas inhales during melting, may cause acute poisoning and chronic or cumulative health impairment including cancer.

Environmental effects

Pay attention to the concentrations of discharge density of gas during melting as they may damage the ecosystem.
