HAZARDS IDENTIFICATION

Potential Health Effects
INHALATION

ETHANE, 1,1,1,2-TETRAFLUORO­Gross overexposure may cause: Central nerous system depression with dizziness, confusion,
incoordination, drowsiness or unconsciousness. Inhalation of high concentrations of vapor is harmful
and may cause heart irregularity unconsciousness or death. Intentional misuse or deliberate
inhalation may cause death without warning. Vapor reduces oxygen available for breathing and is
heavier than air. Liquid contact can cause frostbite.

HUMAN HEALTH EFFECTS:

SKIN CONTACT

ETHANE, 1,1,1,2-TETRAFLUORO­Immediate effects of overexposure may include frostbite. If liquid or escaping vapor contacts he
skin. Frostbite-like effects may occur if the liquid or escaping vapors contact the eyes.

Inhalation may include temporary nervous system depression with anesthetic effects such as
dizziness, headache, confusion, incoordination, and loss of consciousness.

Higher exposures may lead to temporary alteration of the heart's electrical activity with irregular
pulse, palpitations, or inadequate circulation. Fatality may occur from gross overexposure.

Individuals with preexisting diseases of the central nervous or cardiovascular system may have
increased susceptibility to the toxicity of excessive exposures.

CARCINAGENICITY 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

In case of contact, immediately flush area with plenty of lukewarm water for at least 15 minutes,
while removing contaminated clothing and shoes. Call a physician. Wash contaminated clothing
before reuse. Treat for frostbite if necessary by gently warming affected area.

EYE CONTACT

In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a
physician.

FIRST AID MEASURES CONTINUED,

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
only be used with special caution in situations of emergency life support.

FIRE FIGHTING MEASURES

Flammable Properties
Flash Point Will not burn
LEL Not Applicable
UEL Not Applicable
Autoignition >743 C (>1369 F)

HFC-134A is not flammable at ambient temperatures and atmospheric pressure. However, HFC­134A has been shown in tests to be combustible at pressures as low as 5.5 psig at 177 C (351 F)
when mixed with air at concentrations of 60 volume % air. At lower temperatures, higher pressures
are required for combustibility. Experimental data have also been reported which indicate
combustibility of HFC 134A in the presence of certain concentrations of chlorine.

FIRE AND EXPLOSION HAZARDS:
Cylinders may rupture under fire conditions. Decomposition may occur. Contact of welding or
soldering torch flame with high concentrations of refrigerent can result in visible changes in the size
and color of the torch flame. This flame effect will only occur in concentrations of product well
above the recommended exposure limit, therefore stop all work and ventilate the area before
proceeding. Use forced ventilation to disperse refrigerant vapors from the work area before using any
open flames.

Extinguishing Media

As appropriate for combustibles in area. Extinguishant for other burning material in area is sufficient
to stop burning.

Fire Fighting Instructions

Cool tank/container with water spray. Self-contained breathing apparatus (SCBA) is required if
cylinders rupture or 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

Ventilate area, especially low or enclosed places where heavy vapors might collect. Remove open
flames. Use self-contained breathing apparatus (SCBA) for large spills or releases.

HANDLING AND STORAGE

Handling (Personnel/Physical Aspects)

Use with sufficient ventilation to keep employee below recommended limits. HFC-134A should not
mixed with air for leak testing. In general it should be used or allowed to be present with high
concentration air above atmospheric pressure. See Flamable Propertiessaction. Contact with chlorine
or other strong oxidizing agents should also be avoided.

Storage

Store in a Clean, dry area. Do not heat above 52 C (126 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 or
enclosed places. Refrigerant concentration monitors may be necessary to determine vapor
concentrations in work areas prior to use of torches or other open flames, or if employees are entering
enclosed areas.

PERSONAL PROTECTIVE EQUIPMENT

Impervious gloves and chemical splash goggles should be used when handling liquid. Under normal
manufacturing conditions, no respiratory protection is required when using this product. Self­contained breathing apparatus (SCBA) is required if a large release occurs.

TOXICOLOGICAL INFORMATION

ANIMAL DATA
ETHANE, 1,1,1,2-TETRAFLUORO

INHALATION: 4 hour, ALC, rat: 567,000 ppm.

SKIN: The compound is a skin irritant and a slight eye irritant but is not a skin sensitizer in animals.

EYE: A short duration spray of vapor produced very slight eye irritation.

Effects from single high exposures include central nervous system depression, anesthesia, rapid
breathing, lung congestion and microscopic liver changes. Cardiac sensitization occurred in dogs at
50,000 ppm or greater from the action of exogenous epinephrine.

5

No toxic effects or abnormal histopathological observations occurred in rats repeatedly exposed to
concentrations ranging from 10,000 to 50,000 ppm (v/v). Long-term exposures to 50,000 ppm (v/v)
of vapors produced organ weight increases and a decrease in body weight gain, but no increased
mortality or adverse hematological effects, In chronic inhalation studies, HCFC-22, at a
concentration of 50,000 ppm (vlv), produced a small, but statistically significant increase of late­occurring tumors involving salivary glands in male rats, but not female rats or male or female mice.
In the same studies, no increased incidence of tumors was seen in either species at concentrations of
10,000 ppm or 1,000 ppm (v/v).

Long-term administration in corn oil produced no effects on body weight or mortality.

HCFC-22 was mutagenic in some strains of bacteria in bacterial cell cultures, but not mammalian
cell cultures or animals. It did not cause heritable genetic damage in
