Scenario: Ethyl ether in metal container that is over 10 years old. Peroxide content unknown. Container is empty (<3%) to the best of our knowledge. Cap is clear plastic with no visible signs of peroxides. Understand that peroxides can concentrate as the ether evaporates. Setting: High school chemical storage room. Lab pack team has been in to pack chemicals and left the ethyl ether behind because of its potential explosiveness. Questions: How dangerous is this empty can? Does it have to be treated as a hazardous waste? Our understanding is that the peroxide crystals themselves do not have considerable detonation force without the contents of the ether. The ether acts as the fuel for the explosion. Can the empty container go in the normal trash. Your thoughts and comments are appreciated. We have been struggling with this issue; how to deal with legacy empty ether containers. -- Kent A.
