To get the hazardous waste bucket emptied, fill out the form found here:
http://www.stanford.edu/dept/EHS/prod/enviro/waste/pickup/WastePickup_form.htm
Make sure there is a Hazardous Waste tag on the bin when they come pick it up. The table below provides most of the info needed to fill out the online form and the tag.

I just talked to the guy that runs the whole waste pickup thing. He told me just to put Urethane and Silicone and approximate weight. That's it!

Building 02-530, Room 129A, just estimate the volume of waste in the garbage can.
