HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
HCFC-123
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

(HAZARDS IDENTIFICATION - Continued)
breathing and is heavier than air. Product causes mild eye
irritation. Decomposition products are hazardous.
HEALTH HAZARDS:
Eye contact may cause irritation with discomfort, tearing,
or blurring of vision.
Overexposure by inhalation may cause liver damage with
altered enzyme levels, and temporary nervous system
depression with anesthetic effects such as dizziness,
weakness, headache, confusion, incoordination, and loss of
consciousness. With overexposure (>2%), possibly temporary
alteration of the heart鈥檚 electrical activity with irregular
pulse, palpitations, or inadequate circulation.
Increased susceptibility to the effects of this material may
observed in persons with pre-existing disease of the central
nervous system, cardiovascular system, and liver.
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 with water. Get medical attention if
irritation is present.
EYE CONTACT
In case of contact, immediately flush eyes with plenty of water
for at least 15 minutes. Call a physician.
INGESTION
Material poses an aspiration hazard. If swallowed, do not induce
vomiting. Immediately give 2 glasses of water. Never give
anything by mouth to an unconscious person. Call a physician.
2190FR DuPont Page 3
Material Safety Data Sheet
(FIRST AID MEASURES - Continued)
If vomiting occurs naturally, have victim lean forward to reduce
the risk of aspiration.
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.

Material Safety Data Sheet
(ACCIDENTAL RELEASE MEASURES - Continued)
DuPont Emergency Exposure Limits (EEL) are established to
facilitate site or plant emergency evacuation and specify airborne
concentrations of brief durations which should not result in
permanent adverse health effects or interfere with escape. EEL鈥檚
are expressed as airborne concentration multiplied by time (CxT)
for up to a maximum of 60 minutes and as a ceiling airborne
concentration. These limits are used in conjunction with
engineering controls/monitoring and as an aid in planning for
episodic releases and spills. For more information on the
applicability of EEL鈥檚, contact DuPont.
The DuPont Emergency Exposure Limit (EEL) for HCFC-123 is 1000 ppm
for up to 60 minutes with a 1 minute not-to-exceed ceiling of 2500
ppm.
Initial Containment
Dike spill. Prevent material from entering sewers, waterways, or
low areas.
Spill Clean Up
Collect on absorbent material and transfer to steel drums for
recovery/disposal. Comply with Federal, State, and local
regulations for reporting releases.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid breathing high concentrations of vapor. Provide adequate
ventilation for storage, handling, and use, especially for
enclosed or low spaces. Avoid contact of liquid with eyes and
prolonged skin exposure.
Handling (Physical Aspects)
Do not allow product to contact open flame or electrical heating
elements because dangerous decomposition products may form.
Storage
Store in a clean, dry place.
Do not heat above 52 deg C to avoid over pressurizing the
container.
2190FR DuPont Page 5
Material Safety Data Sheet
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Use only with adequate ventilation. Keep container tightly
closed. Vapors 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
Where there is potential for airborne exposures in excess of
applicable limits, wear NIOSH approved respiratory
protection.
PROTECTIVE CLOTHING
Where there is potential for skin contact have available and
wear as appropriate impervious gloves, apron, pants, and
jacket.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
HCFC-123
Dermal ALD, rabbit: >2000 mg/kg
Oral ALD, rat: 9000 mg/kg
Inhalation 4 hour, LC50, rat: 32,000 ppm
Animal testing indicates that HCFC-123 is not a skin
irritant or skin sensitizer, but is a mild to moderate eye
irritant.
Toxic effects noted in animals from single exposure by
inhalation at concentrations of 5000 ppm or greater include
effects on unconditioned reflexes, locomotor activity and
coordination, suggesting anesthetic effects. Single
inhalation exposures caused central nervous system effects,
such as anesthesia, and nonspecific clinical signs and organ
pathology changes. Cardiac sensitization occurred in dogs
at concentrations of 20,000 ppm and greater.
Repeated exposures to 300 ppm and higher resulted in
decreased cholesterol, triglycerides or glucose, and
2190FR DuPont Page 7
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
increased urinary fluoride levels. At 5000 ppm or greater,
anesthetic effects, reduced lymphocyte counts, organ weight
changes, including increased liver weight, and enzyme
alterations, and decreased body weight gain were observed.
Exposure to dogs, guinea pigs or monkeys at 1000 ppm or
greater induced slight or mild liver damage. HCFC-123 was
not neurotoxic in animals repeatedly exposed by inhalation
at concentrations up to 5,000 ppm, but did cause a slight
decrease in arousal at this concentration.
Long-term exposure caused decreased body weight, decreased
cholesterol, triglycerides and glucose, and increased
urinary fluoride concentrations in rats. Inhalation of 300,
1000 or 5000 ppm for two years caused an increase in benign
testicular tumors in male rats. An increase in benign
pancreatic and liver tumors was observed in rats exposed to
1000 or 5000 ppm. The tumors were late-occurring and none
were judged to be life-threatening. The biological
significance of these tumors to man is considered to be
limited. Additionally, evidence of retinal atrophy was
observed in this two-year study in both treated and control
animals, although the toxicological significance is
undetermined.
Animal data indicate that HCFC-123 does not affect
reproductive performance in rats or harm the unborn animal.
HCFC-123 does not produce genetic damage in bacterial cell
cultures or in animals. In two studies, genetic damage was
produced in mammalian cell cultures, but did not produce
genetic damage in another study. Overall weight of evidence
indicates that HCFC-123 is not mutagenic.
