HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
Inhalation of high concentrations of HFC-236fa, such as
those that may be achieved under conditions of abuse or
inappropriate use, may cause adverse central nervous system
and cardiac effects. The effects may include dizziness,
lightheadedness, confusion, weakness and unconsciousness,
and in extreme cases the heart may become sensitized to
6095FR DuPont Page 2
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
epinephrine and may result in death without warning.
HFC-236fa may cause frostbite if liquid or escaping vapor
contacts the skin.
HFC-236fa may cause "frostbite-like" effects if the liquid
or escaping vapors contact the eyes.
Ingestion is not considered a probable route of exposure for
HFC-236fa.
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 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
Flush area with lukewarm water. Do not use hot water. If
frostbite has occurred, call a physician.
EYE CONTACT
In case of contact, immediately 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
THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO ARRHYTHMIAS.
Catecholamines such as adrenaline, and other compounds having
similar effects, should be reserved for emergencies and then used
only with special caution.

----------------------------------------------------------------------
FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Will not burn. Not a fire or explosion hazard. "FE-36" is
used as a fire extinguishant. Hazardous gas/vapor produced
in fire is hydrogen fluoride.
Extinguishing Media
Use media appropriate for surrounding material.
Fire Fighting Instructions
(For example: when "FE-36" is exposed to fire from
surrounding material) - Wear self-contained breathing
apparatus. Wear full protective equipment. Cool
tank/container with water spray.
----------------------------------------------------------------------
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.
Keep upwind of leak - evacuate until gas has dispersed.
Accidental Release Measures
Ventilate area before reentering.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Do not breathe gas. Do not get in eyes, on skin, or on clothing.
Wash thoroughly after handling.
Handling (Physical Aspects)
Keep away from sparks, flames and hot (glowing) surfaces.
# Storage
Valve protection caps and valve cutlet threaded plugs must
remain in place unless container is secured with valve
outlet piped to use point. Do NOT drag, slide or roll
cylinders. Use a suitable hand truck for cylinder movement.
Never attempt to lift cylinder by its cap. Use a pressure
reducing regulator when connecting cylinder to lower
pressure (>3000 psig) piping or systems. Do NOT heat
6095FR DuPont Page 4
Material Safety Data Sheet
(HANDLING AND STORAGE - Continued)
cylinder. Use a check valve or trap in the discharge line
to prevent hazardous back flow into the cylinder.
Cylinders should be stored upright and firmly secured to
prevent falling or being knocked over. Separate full
containers from empty containers. Storage area temperatures
should not exceed 125 deg F (52 deg C) and should be free of
combustible materials. Avoid area where salt or other
corrosive materials are present. Avoid excessive inventory
and storage time. Use a first-in first-out system. Keep
accurate inventory records.
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Use only with adequate ventilation. Keep container tightly closed.
Vapors of the compound are heavier than air, posing a
hazard of asphyxia if they are trapped in enclosed or low
places.
Personal Protective Equipment
EYE/FACE PROTECTION
Wear safety glasses or coverall chemical splash goggles.
RESPIRATORS
Wear NIOSH approved respiratory protection, as appropriate.
PROTECTIVE CLOTHING
Wear impervious clothing, such as gloves, apron, boots, or whole
bodysuit as appropriate.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
HFC 236fa
Inhalation 4 hour LC50: > 457,000 ppm in rats
Single exposure by inhalation caused narcosis and cardiac
sensitization, a potentially fatal disturbance of heart
rhythm associated with a heightened sensitivity to the
action of epinephrine; in a cardiac sensitization screening
test in dogs exposed to concentrations of 50,000 to 250,000
ppm evidence of sensitization occurred at 150,000 ppm.
Repeated exposures caused a reduced startling response in
rats. No other significant toxicological effects were
observed. No-Observed-Adverse-Effect-Level (NOAEL): 20,000
ppm.
Developmental studies conducted in rats and rabbits at dose
6095FR DuPont Page 6
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
levels of 5000, 20,000 or 50,000 ppm produced no evidence of
developmental toxicity. HFC 236fa was not uniquely toxic to
the rat or rabbit conceptus. Specific studies to evaluate
the effect on female reproductive performance have not been
conducted; however, limited information obtained from
studies on developmental toxicity do not indicate adverse
effects on female reproductive performance. Tests have
shown that HFC 236fa does not cause genetic damage in
bacterial or mammalian cell cultures. No animal data are
available to define carcinogenic effects of HFC 236fa.
