[Safety Profile]

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Poison by inhalation and subcutaneous routes. Moderately toxic by ingestion and sktn contact. A severe skin irritant. An experimental teratogen. Mutation data reported. Combustible when exposed to heat or flame; can react with oxidzing materials. Moisture causes liberation of H2SO4. Violent reaction with potassium tert-butoxide. Reacts violently with 3,8-dnitro-6-phenylphenanthridine + water. Reaction with iron + water forms explosive hydrogen gas. To fight fire, use alcohol foam, H2O foam, CO2, dry chemicals. When heated to decomposition it emits toxic fumes of SOx. See also SULFATES.

Hazard InformationBack Directory
[General Description]

A clear colorless liquid with a peppermint odor. Burns, though may be difficult to ignite. Corrosive to metals and tissue.
[Reactivity Profile]

The presence of moisture in a metal container of DIETHYL SULFATE(64-67-5) caused the formation of sulfuric acid which reacts with the metal to release hydrogen which pressurized and exploded the container [Chem. Abst. 28:2908(1934)].
[Air & Water Reactions]

Highly flammable. Slowly reacts with water to form ethyl alcohol, a flammable liquid, and ethyl sulfate, with eventual conversion to sulfuric acid.
[Health Hazard]

May be fatal if inhaled, swallowed or absorbed through skin. Inhalation causes nausea and vomiting. Causes burns to skin and eyes. Ingestion may cause nausea, vomiting abdominal pain and collapse.
