HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
Inhalation of high concentrations of vapor is harmful and
may cause heart irregularities, unconsciousness, or death.
Intentional misuse can be fatal. Vapor reduces oxygen
available for breathing and is heavier than air. Liquid
contact can cause frostbite.
HUMAN HEALTH EFFECTS:
Human health effects of overexposure by inhalation may
include nonspecific discomfort such as nausea, headache, or
weakness; temporary nervous system depression with
anaesthetic effects such as dizziness, headache, confusion,
incoordination, and loss of consciousness; or with gross
overexposure, possibly temporary alteration of the heart鈥檚
electrical activity with irregular pulse, palpitations, or
inadequate circulation. Individuals with preexisting
6087FR DuPont Page 2
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
diseases of the central nervous or cardiovascular system may
have increased susceptibility to the toxicity of excessive
exposures. Eye or skin contact with the liquid may cause
frostbite.
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
IF HIGH CONCENTRATIONS ARE INHALED: Immediately remove to
fresh air. Keep persons calm. Call a physician. If not
breathing, give artificial respiration. If breathing is
difficult, give oxygen.
IN CASE OF SKIN CONTACT: Flush with water. Treat for
frostbite if necessary.
IN CASE OF EYE CONTACT: Flush with water. Call a physician
if frostbite occurs.
IF SWALLOWED: Ingestion is not considered a potential route
of exposure.
Notes to Physicians
Because of possible disturbances of cardiac rhythm,
catecholamine drugs, such a epinephrine, should be
considered only as a last resort in life-threatening
emergencies.
----------------------------------------------------------------------
FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Flash Point : Will not burn
Flammable limits in Air, % by Volume
LEL : Not applicable.
UEL : Not applicable.
Fire and Explosion Hazards:
Use water spray or fog to cool containers. Cylinders are
equipped with temperature and pressure relief devices but
may still rupture under fire conditions. Decomposition
may occur, producing HF, CO and possibly COF2.
6087FR DuPont Page 3
Material Safety Data Sheet
(FIRE FIGHTING MEASURES - Continued)
Extinguishing Media
Use media appropriate for surrounding material.
Fire Fighting Instructions
Self-contained breathing apparatus (SCBA) is required if
cylinders rupture or release under fire conditions. Water
runoff should be contained and neutralized prior to release.
----------------------------------------------------------------------
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
Material evaporates at atmospheric pressure (vaporizes).
Ventilate area - especially low places where heavy vapors
might collect. Remove open flames.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid contact of liquid with eyes and prolonged skin
exposure. Use with sufficient ventilation to keep employee
exposure below recommended limits.
Storage
Clean, dry area. Do not heat above 51.7 deg. C (125 deg. F)
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Normal ventilation for standard manufacturing procedures is
generally adequate. Local exhaust should be used when large
amounts are released. Mechanical ventilation should be used
in low places.
6087FR DuPont Page 4
Material Safety Data Sheet
(EXPOSURE CONTROLS/PERSONAL PROTECTION - Continued)
Personal Protective Equipment
Neoprene rubber or leather gloves should be used when
handling liquid. Chemical splash goggles should be worn
when handling liquid. 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.

STABILITY AND REACTIVITY
----------------------------------------------------------------------
Chemical Stability
Material is stable. However, avoid open flames and high
temperatures.
Decomposition
This product can be decomposed by high temperatures (open
flames, glowing metal surfaces, etc.) forming HF, COF2 or
CO. These materials are toxic and irritating. Contact
should be avoided.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
TRIFLUOROMETHANE:
Inhalation 4-hr LC50 : >663,000 ppm in rats
Material is untested for skin and eye irritancy, and for
animal sensitization.
Effects from single high inhalation exposure to
Trifluoromethane include anaesthetic effects, and
nonspecific effects such as weight loss were observed at
concentrations >22%. No cardiac sensitization was observed
in dogs after breathing 800,000 ppm for periods of 5-10
minutes following epinephrine challenge. In another test,
dogs exposed to up to 30% or up to 50% (with aditional
oxygen), had no positive responses. No cardiac
sensitization occurred in baboons exposed by inhalation to
10%, 30%, 50%, or 70% Trifluoromethane before or after an
epinephrine challenge; there was a dose-related decrease in
heart rates and differences in respiratory rates during
exposure.
No animal tests are available to define the carcinogenic
hazards of Trifluoromethane. The maternal and developmental
NOAEL was 50,000 ppm. Trifluoromethane is not considered a
unique developmental hazard to the conceptus. There were no
developmental or reproductive effects.
Tests have shown that Trifluoromethane does not produce
genetic damage in bacterial or mammalian cell cultures. It
has not produced genetic damage in tests on animals.
HEXAFLUOROETHANE:
Inhalation 4-hour LC50: >800,000 ppm in rats
Effects observed in animals by inhalation include decreased
growth rate, pulmonary changes, irregular respiration,
increased urine volume and creatinine, reversible
pathological changes in the kidneys, and increased urinary
fluoride concentration. One study showed no arrhythmogenic
effects in dogs at a concentration of 20%, while another
study did show some arrhythmogenic effects in both guinea
pigs and dogs. Long-term inhalation exposures resulted in
an initial decrease in growth rate, but no other adverse
changes were noted. No animal test reports are available

to define carcinogenic, developmental, or reproductive
hazards. The compound does not produce genetic damage in
bacterial cell cultures but has not been tested in animals.
