HAZARDS IDENTIFICATION
----------------------------------------------------------------------
# Potential Health Effects
Inhalation of high concentrations of vapor is harmful and
may cause heart irregularities, unconsciousness or death.
Intentional misuse or deliberate inhalation may cause death
without warning. Vapor reduces oxygen available for
breathing and is heavier than air. Decomposition products
are hazardous. Liquid contact can cause frostbite.
HUMAN HEALTH EFFECTS:
Skin contact with liquid Dimethyl Ether may produce
2006FR DuPont Page 2
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
frostbite. There are no reports of human sensitization.
Eye contact with Dimethyl Ether vapor may produce eye
irritation with discomfort, tearing, or blurring of vision.
Inhalation may cause nonspecific discomfort, such as nausea,
headache, or weakness. Higher exposures may lead to
temporary nervous system depression with anaesthetic effects
such as dizziness, headache, confusion, incoordination, and
loss of consciousness; or increased susceptibility to the
cardiac arrhythmic effects of epinephrine.
Carcinogenicity Information
None of the components present in this material at concentrations
equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH
as a carcinogen.
----------------------------------------------------------------------
FIRST AID MEASURES
----------------------------------------------------------------------
First Aid
INHALATION
If high concentrations are inhaled, immediately remove to
fresh air. Keep person calm. If not breathing, give
artificial respiration. If breathing is difficult, give
oxygen. Call a physician.
SKIN CONTACT
In case of contact, flush skin with water for at least 15
minutes. Treat for frostbite if necessary by gently
warming affected area. Call a physician if irritation is
present.
EYE CONTACT
In case of contact, flush eyes with plenty of water for
at least 15 minutes. Call a physician.
INGESTION
Ingestion is not considered a potential route of
exposure.
Notes to Physicians
Because of possible disturbances of cardiac rhythm,
catecholamine drugs, such as epinephrine, should be used
with special caution only in situations of emergency life
support.

FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Flash Point : -41 C (-42 F)
Method : TOC
Flammable limits in Air, % by Volume
LEL : 3.4
UEL : 18.0
Autoignition : 350 C (662 F)
Autodecomposition : Not determined
Fire and Explosion Hazards:
Extremely flammable. Vapors are heavier than air and may
travel to source of ignition and flash back. Avoid high
temperature and static charges. Containers have pressure
and temperature relief devices, but still may rupture under
fire conditions. Explosion is possible.
Extinguishing Media
Water Spray, Water Fog, Dry Chemical.
"Alcohol" Foam. Carbon Dioxide (CO2).
Fire Fighting Instructions
Keep container cool with water spray or fog. If gas exiting
container ignites, stop flow of gas. Do not put out the
fire unless leak can be stopped immediately. Self-contained
breathing apparatus (SCBA) is required if containers rupture
and contents are released under fire conditions.
----------------------------------------------------------------------
ACCIDENTAL RELEASE MEASURES
----------------------------------------------------------------------
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL)
sections before proceeding with clean-up. Use appropriate
PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Accidental Release Measures
Close all source valves and guard against sparks or ignition
sources. Evacuate area. Keep upwind of leak. Ventilate
area, especially low or enclosed places where heavy vapors
might collect. Self-contained breathing apparatus (SCBA)
should be used for large spills. Comply with Federal, State
and local regulations on reporting releases.
If this product is spilled and not recovered, or is
recovered as a waste for treatment or disposal, the CERCLA
Reportable Quantity is 100 lbs. (Release of an unlisted

Hazardous Waste Characteristic of ignitability).
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid breathing high concentrations of vapors and avoid
liquid contact with skin or eyes. Use in well-ventilated
area away from possible ignition sources. Lines and
equipment which will contain dimethyl ether should be
pretested with nitrogen using soapy water to detect leaks.
Use with sufficient ventilation to keep employee exposure
below recommended limits.
Storage
Keep container tightly closed and away from heat, sparks
and flame. Keep container in a cool, clean and dry area.
Do not heat above 52 deg C (125 deg F). Store away from
oxygen cylinders or other oxidizing materials and possible
ignition sources. Ground all equipment and cylinders before
use.
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Normal ventilation for standard manufacturing procedure is
generally adequate. Local exhaust should be used when large
amounts are released or when flammable or exposure limits
might be exceeded. Mechanical ventilation should be used in
low or enclosed places. Ground all equipment and cylinders
before use. Use explosion-proof electrical equipment rated
Class I, Group C of the National Electrical Code in Division
I locations. In Division 2 locations, all spark-producing
electrical equipment must be explosion-proof and rated Class
I, Group C. Non-sparking motors need not be
explosion-proof. Equipment should be clean and dry and
purged with nitrogen before being put into service.
Personal Protective Equipment
Impervious gloves should be used when handling liquid.
Chemical splash goggles should be worn if liquid contact
with the eyes is possible. Fire protective clothing (NOMEX)
with antistatic control should be worn when handling this
product. Under normal manufacturing conditions, no
respiratory protection is required when using this product.
Self-contained breathing apparatus (SCBA) is required if a
large spill or release occurs.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
# Animal Data
Dimethyl Ether
Inhalation 4 hour LC50: 164,000 ppm in rats
Toxic effects in animals from inhalation exposure include
anaesthetic effects and decreased blood pressure. Cardiac
sensitization occurred in dogs exposed to concentrations of
20% or greater. Repeated exposure caused changes in white
blood cell counts, anaesthesia, and reduced weight gain.
Long-term exposure of rats to 20,000 ppm caused liver weight
reduction and alterations of liver enzymes levels. In
another study, observations include decreased red blood cell
counts, spleen changes, and decreased survival of males at
10,000 and 25,000 ppm; red blood cell destruction
(hemolysis) occurred at 25,000 ppm.
Tests in animals demonstrate no carcinogenic or
developmental toxicity. Tests in animals for reproductive
effects have not been
Dimethyl Ether did not produce genetic damage in bacterial
cell cultures but has not been tested in animals.
