Comments

In animal studies at lethal concentrations, dimethyl ether acts as a general anesthetic. [ChemIDplus] Liquid will cause frostbite. [CHRIS] Dimethyl ether is in the list of "Some volatile substances which may be abused by inhalation" published on the web site of the U.N. International Drug Control Programme, indicating its potential to cause narcosis in workers. [Reference #1] Caused slight intoxication at 50,000 ppm, some incoordination at 82,000 ppm, an unconsciousness at 200,000 ppm (after 17 minutes) in human volunteers; [AIHA]
