Use
The acute toxicity of diethyl ether is low. Inhalation of high concentrations can cause sedation, unconsciousness, and respiratory paralysis. These effects are usually reversible upon cessation of exposure. Diethyl ether is mildly irritating to the eyes and skin, but does not generally cause irreversible damage. Repeated contact can cause dryness and cracking of the skin due to removal of skin oils. The liquid is not readily absorbed through the skin, in part because of its high volatility. Diethyl ether is slightly toxic by ingestion. Diethyl ether is regarded as having adequate warning properties. There is no evidence for carcinogenicity of diethyl ether, and no reproductive effects have been reported. Chronic exposure to diethyl ether vapor may lead to loss of appetite, exhaustion, drowsiness, dizziness, and other central nervous system effects.
