Have I inadvertely diethyl ether peroxides?

About 1 week ago, I used diethyl ether to wash some solid products.


I dumped it in my temporary waste container, which also contains water and some other solvents like DCM.


I returned today, and discovered that my waste container is full of yellow to brown crystals, and possibly some oil of similar color.


Needless to say I didnt stick around for long to investigate or even touch anything, as I realized that I might have turned my fume hood into a minefield (ether peroxides are friction explosive).


I wilk of course E&HS at my faculty, but it's saturday so no one is around.


Is it plausible that I've made dangerous peroxides? Has anyone else done the very stupid thing which is to store diethyl ether alongside with water in an open container for 1 week?
