We use the glass disposal boxes for clean glass only. Each box has a hand broom and dust pan sitting on top of it . It is inconvenient to dispose of anything without first moving the broom and dust pan out of the way, as they sort of obstruct the opening. I have not experienced the problem with other items getting tossed in with the glass. Labs are provided with a regular trash can under each pair of work stations, so students would have to walk out of their way to use the glass boxes. Contaminated glass, such as from a dropped beaker or flask containing a hazardous chemical, is disposed as hazardous waste in a rigid container.

Hi all,

While I recognize that this is not totally relevant to this group, I want to ask people about broken glass and how they handle/manage it. For us - we have performed EPA audits (by EPA lawyers as well as IDEM) and discovered that it does not need to be handled as hazardous waste, and thus can be disposed of in regular trash. However, managing broken glass is mostly an OSHA thing to protect our staff who clean rooms and dispose of regular refuse.

So for us - the way I presently handle it is to have large boxes in labs for disposal of glass. When they fill, I go around, pick them up, and take them to the dumpster - where they are then taken to our local trash transfer station.

With that said - I routinely purchase broken glass boxes (3' high boxes that are clearly labeled - you all know them). Students quickly fill these up with used gloves, kimwipes, pipets, and other random things.

My question is this: Has anybody been successful at having such boxes around and ending up with them filled with only glass? Should I use smaller boxes placed in hoods, or just smaller boxes on bench tops or ?????? I'm just looking for options - these boxes are a bit expensive but also they are dangerous. I've had a few incidents where I've picked up a full box and a pipet speared through the box right in to my hand. The weight is a bit much - so I'm certain to go to bench top ones and ones in hoods.

I was just curious as to what others have found that works. The situation I presently have does not work well - at least not with undergrads.
