Safety:

Diethyl ether is highly volatile and its vapors are extremely flammable. The fact that diethyl ether vapors are denser than air makes it even more dangerous because the vapors tend to 'hang around' longer. Diethyl ether also tends to slowly form explosive peroxides over time. Bottles that have been open typically should be checked every three months for peroxide formation. After one year it is typically recommended to dispose of bottles of diethyl ether that have been opened. Diethyl ether also has anesthetic properties and has potential as a recreational drug due to its euphoric properties upon exposure.
