There is no evidence for carcinogenicity of diethyl ether, and no reproductive effects heavier than air, it may travel a considerable distance to an ignition source and flash Ether is used in the production of Grignard reagents. Human systemic Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis. Diethyl ether is extremely flammable (NFPA rating = 4) and is one of the most dangerous fire hazards commonly encountered in the laboratory, owing to its volatility and extremely low ignition temperature. The reaction to make diethyl ether is reversible, so eventually an equilibrium between reactants and products is achieved.

The liquid is not readily absorbed through the skin, in part because of its high volatility. Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. ethyl ether is a solvent that may cause skin irritation. For example, dimethyl ether and ethanol (both having the molecular formula C 2 H 6 O) are completely soluble in water, whereas diethyl ether and 1-butanol (both C 4 H 10 O) are barely soluble in water (8 g/100 mL of water).
