| Hazard Information | Back Directory | [Chemical Properties]
Ethylene oxide is a colorless, compressed, liquefied gas or liquid (below 11℃). Sweet odor; the odor
threshold is 50 ppm. | [Potential Exposure]
Ethylene oxide is a man-made chemical used in the production of glycols (ethylene glycol, polyglycols, glycol ethers, esters), nontonic surface-active
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
intermediate | [First aid]
If ethylene oxide gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts
the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from
exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has
stopped and CPR if heart action has stopped. Transfer
promptly to a medical facility. When this chemical has
been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. If frostbite has occurred, seek
medical attention immediately; do NOT rub the affected
areas or flush them with water. In order to prevent further
tissue damage, do NOT attempt to remove frozen clothing
from frostbitten areas. If frostbite has NOT occurred,
immediately and thoroughly wash contaminated skin with
soap and water. Medical observation is recommended for
24 to 48 hours after breathing overexposure, as pulmonary
edema may be delayed. As first aid for pulmonary edema,
a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. | [Shipping]
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 | [Incompatibilities]
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. | [Waste Disposal]
Return refillable compressed
gas cylinders to supplier. Concentrated waste containing no
peroxides-discharge liquid at a controlled rate near a pilot
flame. Concentrated waste containing peroxides-perforation
of a container of the waste from a safe distance followed
by open burning |
