agent; ethanolamines, acrylonitrile, plastics. It is also used
as a fumigant for foodstuffs and textiles; an agricultural
fungicide; and for sterilization, especially for surgical
instruments. It is used in drug synthesis and as a pesticide

UN1040 Ethylene oxide or Ethylene oxide with
nitrogen up to a total pressure of 1 MPa (10 bar) at 50℃,
Hazard Class: 2.3; Labels: 2.3-Poisonous gas, 2.1-
Flammable gas, Inhalation Hazard Zone D. Cylinders must
be transported in a secure upright position, in a wellventilated truck. Protect cylinder and labels from physical
damage. The owner of the compressed gas cylinder is the
only entity allowed by federal law (49CFR) to transport
and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express
written permission of the owner

May form explosive mixture with air.
Chemically unstable. Dangerously reactive; may rearrange
chemically and/or polymerize violently with evolution of
heat; when in contact with highly active catalytic surfaces,
such as anhydrous chlorides of iron, tin and aluminum;
pure oxides of iron and aluminum; and alkali metal hydroxides. Even small amounts of strong acids; alkalis, or oxidizers can cause a reaction. Avoid contact with copper.
Protect container from physical damage, sun and heat.
Attacks some plastics, rubber or coatings.
