Is broken glass considered hazardous material?

It can be sharp, which makes it hazardous, so yes it can be hazardous. Glass is only dangerous if it is broken, because the pieces tend to be extremely sharp. Keep your kids away from broken glass to avoid any glass being stabbed in their heel.... I play with glass (not like hot potatoe or anything) but i use it for cooking sometimes and i have never ever cut my self with out breaking it. My really genius friend said that they found diamonds on the side of the road in out street and they picked it up and cut them selves. I smashed it with my tennis shoe and i said that it was glass because diamonds can't break by being stepped on...
