Safety Information
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.
