(manufacturer recommended)
SECTION 3: HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Colorless, volatile liquid with an ethereal and faint sweetish odor.
Non-flammable material. Overexposure may cause dizziness and loss of
concentration. At higher levels, CNS depression and cardiac arrhythmia
may result from exposure. Vapors displace air and can cause
asphyxiation in confined spaces. At higher temperatures, (greater than
250 C), decomposition products may include hydrofluoric acid and
carbonyl halides.
POTENTIAL HEALTH EFFECTS:
ACUTE HAZARDS:
INHALATION: Genetron 134a is of low acute toxicity in animals. When
oxygen levels in air are reduced to 12-14% by displacement, symptoms of
asphyxiation, loss of coordination, increased pulse rate and deeper
respiration will occur. At high levels, cardiac arrhythmia may occur.
SKIN CONTACT: Irritation would result from a defatting action on
tissue.
EYE CONTACT: Liquid contact can cause irritation, which may be severe.

GTRN-0011
Mist may irritate.
INGESTION: Although ingestion is unlikely, discomfort in the
gastrointestinal tract would result from rapid evaporation (boiling) of
the material, and consequent evolution of gas. In addition, some of the
effects of inhalation would be expected. Necrosis from freezing of
tissue could occur.
CHRONIC EFFECTS: None known.
CARCINOGEN: None of the components of this product is listed as a
carcinogen or suspected carcinogen by IARC, NTP or OSHA.
SECTION 4: FIRST AID MEASURES
INHALATION: Immediately remove to fresh air. If breathing has stopped,
give artificial respiration. Use oxygen as required, provided a
qualified operator is available. Call a physician. Do not give
epinephrine (adrenaline).
SKIN CONTACT: Promptly flush skin with water until all the chemical is
removed. If there is evidence of frostbite, bathe (do not rub) with
lukewarm (not hot) water. In the absence of water, cover with a clean,
soft cloth or similar covering. Call a physician.
EYE CONTACT: Immediately flush eyes with large amounts of water for at
least 15 minutes (in case of frostbite, water should be lukewarm - not
hot), lifting eyelids occasionally to facilitate irrigation. Get
immediate medical attention if symptoms persist.
INGESTION: Ingestion is unlikely because of the physical properties of
Genetron 134a, and is not expected to be hazardous. Do not induce
vomiting unless instructed to do so by a physician.
NOTES TO PHYSICIAN: Because of possible disturbances of cardiac rhythm,
catecholamine drugs such as epinephrine should be used with special
caution only in situations of emergency life support. Treatment of
overexposure should be directed at the control of symptoms and the
clinical conditions.

flammable).

GTRN-0011
SPECIAL FIRE FIGHTING PROCEDURES: Firefighters should wear
self-contained, NIOSH-approved breathing apparatus for protection
against possible toxic decomposition products. Proper eye and skin
protection should be provided. Use water spray to keep fire-exposed
containers cool.
UNUSUAL FIRE HAZARDS: Genetron 134a is not flammable at ambient
temperatures and atmospheric pressure. However, this material will
become combustible when mixed with air under pressure and exposed to
strong ignition sources. Contact with certain reactive metals may
result in the formation of explosive or exothermic reactions under
specific conditions (e.g. very high temperatures and/or appropriate
pressures).
HAZARDOUS COMBUSTION PRODUCTS: Halogens, halogen acids and possibly
carbonyl halides.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Always wear recommended personal protective equipment. Evacuate
unprotected personnel. Protected personnel should remove ignition
sources and shut off leak, if without risk, and provide ventilation.
Unprotected personnel should not return until the air has been tested
and determined safe, including low-lying areas.
SECTION 7: HANDLING AND STORAGE
Avoid breathing vapors and liquid contact with eyes, skin, or
clothing.
Do not puncture or drop cylinders, expose them to open flame or
excessive heat.
Use authorized cylinders only.
Follow standard safety precautions for handling and use of cylinders
of liquified gases.
Genetron 134a should not be mixed with air above atmospheric pressure
for leak testing or any other purpose.
Store in a cool, well-ventilated area of low risk and out of direct
sunlight. Protect cylinder and its fittings from physical damage.
Storage in subsurface locations should be avoided. Close valve tightly
after use and when empty.
SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
VENTILATION: Provide local ventilation at filling zones and areas
where leakage is probable. Mechanical (general) ventilation may be
adequate for other operating and storage areas.
RESPIRATORY PROTECTION: None generally required for adequately
ventilated work situations. For accidental release or non-ventilated
situations, or release into confined space where concentration may be

GENETRON(R) 134a
GTRN-0011
above the recommended exposure limit of 1,000 ppm, use a
self-contained, NIOSH-approved breathing apparatus or supplied air
respirator. For escape: use the former or a NIOSH-approved gas mask
with organic vapor canister.
GLOVES: Skin contact with refrigerant gas may cause frostbite.
General work clothing and gloves (leather) should provide adequate
protection. If prolonged contact with the liquid or gas is
anticipated, insulated gloves constructed with PVA, neoprene or butyl
rubber should be used. Any contaminated clothing should be promptly
removed and washed before reuse.
EYE PROTECTION: For normal use, wear safety goggles. Where there is a
reasonable probability of liquid contact, wear chemical safety
goggles.
OTHER PROTECTIVE EQUIPMENT/CLOTHING: Where contact with liquid is
likely, impervious boots and clothing should be used in case of
spillage or leakage, or if there is the probability of contact with
liquid product. High dose-level warning signs are recommended for
areas of principal exposure. Provide eyewash stations and quick-drench
shower facilities at convenient locations. For tank cleaning
operations, see OSHA regulations.
