X: SITUATIONS REQUIRING SPECIALIZED HANDLING
EMERGENCY OVERVIEW:
A colorless volatile, pressurized liquid with slight ether-like odor. As with any chemical, dose and exposure are critically
important variables to understand any potential treatment. Short-term exposure to high concentrations may result in
central nervous system and cardiac effects. Long-term exposure to concentrations above those time weighted averages
recommended herein may result in liver effects.
HEALTH HAZARDS:
Inhalation: Inhalation of high concentrations of vapor may cause central nervous system effects such as dizziness,
drowsiness, anesthesia, or unconsciousness. Anesthetic effects may occur at concentrations of 5000ppm v/v or
above. At concentrations of 20,000 ppm or higher, HCFC-123 may causes increased sensitivity of the heart to
adrenaline which might cause irregular heart beats and possible ventricular fibrillation or death. Long-term exposure
to concentrations above those time weighted averages recommended may cause liver damage with altered enzyme
levels and central nervous system depression. When used on a fire, hazardous decomposition products are formed,
but typically are within safe emergency exposure limits.
Eye contact: May cause irritation, tearing, or blurring of vision, which result in part due to the cooling effect of HCFC-123
evaporation.
Skin contact: Evaporative cooling can result in chilling sensations or frostbite effects. Repeated exposure to the skin
can result in dermatitis. Prolonged skin contact should be avoided, but short-term contact is not considered hazardous.
Ingestion: Not likely to occur in industrial use. Highly volatile liquid.
This material is NOT LISTED by OSHA, NTP, or IARC as a CARCINOGEN.

FLAMMABLE PROPERTIES
FLASH POINT: None.
FLASH POINT METHOD: Not applicable.
AUTOIGNITION TEMPERATURE: Not determined.
UPPER FLAMMABILITY LIMIT (volume % in air): Not applicable.
LOWER FLAMMABILITY LIMIT (volume % in air): Not applicable.
EXTINGUISHING MEDIA: The properties of this chemical make it an ideal extinguishing media its self.
SPECIAL FIRE FIGHTING PROCEDURES: Ensure that the area where the fire occurred is well ventilated before re-
entering. Wear protective clothing. Use water spray or fog to cool storage containers to help prevent an uncontrolled
pressure release.
UNUSUAL FIRE AND EXPLOSION HAZARDS: The concentrated agent when applied to fire can produce toxic by-
products specifically hydrogen halides, which can cause damage. Avoid inhalation of these materials by evacuating and
ventilating the area.
6. ACCIDENTAL RELEASE MEASURES
IN CASE OF SPILL OR OTHER RELEASE:
鈥? In the event of a large spill, allow for adequate ventilation, and do not re-enter an area without an SCBA
until adequate ventilation is accomplished.
鈥? For spills that might result in overexposure, evacuate the area and use protective gear and SCBA鈥檚.
鈥? Avoid leakage into waterways because HCFC-123 is damaging to vegetation.
鈥? Do not expose storage containers to fire, as uncontrolled pressure releases may result.
鈥? The HCFC-123 vapors are heavier than air; therefore use caution when large volume releases occur in
low-lying areas where concentrated vapors may accumulate.
鈥? Recommended 1 Hr. Emergency Exposure Limit: 1000 ppm (v/v) on the same basis as above.
鈥? Recommended 1 Min. Emergency Exposure Limit: 2500 ppm (v/v) on the same basis as above.
鈥? Any food items that were directly sprayed by the liquid should be thrown away, and all surfaces that are
used for food service should be washed (as normal) before re-use.
鈥? WASTE DISPOSAL: Observe all federal, state, and local regulations for products of this type when
accomplishing disposal.
鈥? SECTION 313 SUPPLIER NOTIFICATION: This product contains more than 93% by weight 2,2-dichloro-
1,1,1-trifluoroethane (CAS #306-83-2) which is subject to the reporting requirements of section 313 of
the Emergency Planning and Community Right-To-Know Act of 1986 (40CFR372).
7. HANDLING AND STORAGE
NORMAL HANDLING: (See section 8 for recommended personal protective equipment.) Avoid prolonged contact with
the skin and eyes. Avoid inhaling material and ensure that good ventilation is present when handling. Wash after handling
and follow good personal hygiene and good housekeeping practices. Keep containers closed and transfer material using
closed systems. Handle in a manner to minimize spills.
Additional Note: Approved DOT shipping containers are a normal safe method of storage. Containers should be
maintained in good condition. Do not allow material to remain in deteriorating containers. Because this product can
volatilize, special care should be taken for over pressurization hazards if the containers are overheated or near a radiant

heat source. Protective shoes, such as steel toed shoes, should be worn in addition to the other specified personal
protective equipment (PPE) when handling bulk containers. Eye protection with splash protective side shields should be
used when any possibility of splash or spray exists
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: Ventilate as necessary to minimize exposure levels. Inspect and clean ventilation systems
regularly. Prolonged use should occur only in areas with adequate ventilation. Keep storage containers tightly closed.
Vapors are heavier than air posing a potential hazard if large volumes are trapped in enclosed or low places.
PERSONAL PROTECTIVE EQUIPMENT:
鈥? Wear protective clothing when handling a leak in a storage container (does not apply to fire protection
equipment servicing, other than safety goggles and gloves if large volumes can be exposed to skin).
鈥? Neoprene, PVC or PVA gloves should be worn when handling material for prolonged periods. Short
exposures to skin are not likely to pose a hazard.鈥?
Respiratory protection is not normally needed, however, if handled in enclosed spaces where applicable
exposure limits might be exceeded, a Self Contained Breathing Apparatus (SCBA) should be used.
鈥? When performing filling or servicing operations, PERFORM THESE ACTIVITIES IN A WELL-VENTILATED
AREA.
If handling materials outside a closed, sealed system such that the possibility of splashing exists, wear safety
glasses with side shields. This statement is not intended to apply to use of a fire extinguisher where the nozzle
arrangement is intended to direct the discharge away from the user of the extinguisher.
TIME WEIGHTED EXPOSURE LIMITS: (For persons regularly exposed to material)
鈥? Workplace Environmental Exposure Level, WEEL (AIHA) (8 hrs.): 50 ppm (v/v), based on the primary

OTHER TOXICITY INFORMATION:
鈥? Animal Studies: For 2,2-dichloro-1,1,1-trifluoroethane (CAS #306-83-2):
Long-term exposure in a two year study (6 hours/day, 5 days/week) at concentrations of 300, 1000 and
5000 ppm decreased body weight, serum cholesterol, triglycerides and glucose, and increased urinary
fluoride concentrations in rats. However, survival was significantly improved in all exposed groups
compared to control animals. Inhalation of 300, 1000 and 5000 ppm caused an increase in benign
tumors of the liver, pancreas, and testis. Tumors occurred late in life and none were assessed to be life
threatening. Tumor formation is thought to occur through non-genotoxic mechanisms associated with a
peroxisome proliferating potential or with hormonal disturbances in older rats.
Exposure to dogs, guinea pigs or monkeys at 1000 ppm or greater for 6 hrs. /day, 7 days per week, for a
total of 3 weeks, induced slight or mild liver damage with altered enzyme levels.
Rodent studies indicate HCFC-123 is easily absorbed via inhalation. It distributes in all organs, more so
in the liver. About 90% of inhaled HCFC-123 is eliminated via the lungs unchanged. The remaining
amount is metabolized to trifluoroacetic acid and excreted in the urine. Small amounts of
trifluoroacetylated proteins were detected in rats in laboratory studies.
HCFC-123 did not affect reproductive performance in rats or harm the unborn animals in rats or rabbits at
5000 and 10,000 ppm.
HCFC-123 was inactive in several test-tube genetic damage studies except the human lymphocyte
chromosome aberration assay. HCFC-123 is also inactive in live animal genetic damage studies.
Therefore, it is not considered genotoxic.
