Ralph – you appear to have two objectives here – one, to get lab workers to think about proper waste management, and second, to have them help with the characterization that flows into your disposal option table. I have always found that the University of Wisconsin (Madison) has the best reference for this, going back to the 1980’s (thank you, Peter Reinhardt).  Their lab safety manual indentifies every waste stream I can think of and puts it in a class… then provides a specific disposal technology and instructions.  I could say more, but I’ll let the document speak for itself. Chapters 7, 8 and 9, with easy links, cover chemical waste, lab animal/tissue waste, and pathogens/sharps/medical waste, respectively. http://www.ehs..wisc.edu/laboratorysafetyguide.htm

Subject: [DCHAS-L] Laboratory waste plan template

One of the on going challenges for laboratories is the many different waste regulations associated with materials no longer of use in labs. Wastes with random mixes of biological, chemical, sharps, radiation, animal parts, etc. components frustrate everyone in determining what is the most practical legal disposal method for a particular material. And these solutions are likely to vary from location to location depending on local resources and regulations.

One idea I have for addressing this situation is developing a laboratory waste plan template that would help laboratory workers describe the materials they are ready to dispose of in a way that leads them to the best alternative for getting rid of, for example, environmental bacteria which have been fed uranyl acetate (this week's highlight so far). I wonder if anyone in CHAS land has developed such a template for their institution? At first blush, it seems like an interactive flowchart on a web platform would be the kind of thing I'm thinking about, but so far I haven't seen something that appears suitable for this application. Any suggestions would be appreciated.

Let me know if you have any questions about this.
