POTENTIAL HEALTH EFFECTS:
Ingestion: Extremely unlikely to occur in use.
Eye contact: Liquid splashes or spray may cause freeze burns.
Skin contact: Liquid splashes or spray may cause freeze burns.
Skin absorption: This product will probably not be absorbed through human skin.
Inhalation: Exposure to high vapor concentrations can induce anesthetic effects progressing
from dizziness, weakness, nausea, to unconsciousness. Very high exposures can cause
abnormal heart rhythm, which is potentially fatal. It can act as an asphyxiant by limiting available
oxygen.
Other effects of overexposure: None expected.
4. FIRST AID MEASURES
Skin: Immediately wash with plenty of warm water (do not rub). Thaw affected area with water.
Remove contaminated clothing. Caution: clothing may adhere to the skin in case of freeze burns.
If symptoms (irritation or blistering) develop, get medical attention.
Eyes: Immediately flush with plenty of water. After initial flushing, remove any contact lenses and
continue flushing for at least 15 minutes. Hold eyelids open during flushing. Have eyes
examined and treated by medical personnel.
Ingestion: Highly unlikely, but should this occur, freeze burns will result. Do not induce vomiting
unless instructed to do so by a physician.
Inhalation: Move victim to fresh air. Keep warm and at rest. If breathing is labored, give oxygen.
If only breathing has stopped, give artificial respiration with a pocket mask equipped with a oneway valve to prevent exposure to product or body fluids. If breathing has stopped AND there is
no pulse, give cardiopulmonary resuscitation (CPR). Get immediate medical attention.
Note to physician: Symptomatic and supportive therapy, as indicated. Administration of
epinephrine or similar sympathomimetic drugs should be with special caution and only in
situations of emergency life support as cardiac arrhythmias may result.
5. FIRE FIGHTING MEASURES
Flash Point: Does not flash.
Flammable Limits (Lower): Not applicable.
Flammable Limits (Upper): Not applicable.
Auto Ignition Temperature: > 743°C (> 1369°F)
Hazardous Reactions: Reacts with finely divided metals such as aluminum, zinc,
magnesium, and alloys containing more than 2% magnesium. Can react violently if in
contact with alkali metals and alkaline earth metals such as sodium, potassium, or barium.
During a fire the product can form toxic and corrosive gases such as hydrogen fluoride.
Fire and Explosion Hazards: Compressed liquefied gas. Containers may burst under
intense heat. Ruptured cylinders may rocket or fragment. Heavy vapor may suffocate.

HFC-134a is not flammable in air under ambient conditions of temperature and pressure.
Under conditions of high temperature and pressure, certain HFC-134a/air mixtures were
shown to be flammable. Certain mixtures of HFC-134a and chlorine may be flammable
under some conditions.
Extinguishing Media: As appropriate for surrounding materials/equipment.
Fire Fighting Procedures: Water spray should be used to cool containers.
Fire Fighting Protective Equipment: Use self-contained breathing apparatus with a full-
face piece and special protective clothing.
6. ACCIDENTAL RELEASE MEASURES
Contents under pressure. Ruptured cylinder may rocket or fragment. This product is a liquefied
gas, which exits the container at temperatures capable of causing freeze burns (frostbite).
Precautions should take into account the severity of the leak or spill.
Move unprotected personnel upwind of leaking container. Remove ignition sources and ventilate
the spill area. Use recommended personal protection and shut off the leak, if without risk. If
possible, elevate leak position to highest point of container (should leak gas, not liquid). Water
should never be put on leak nor should cylinder be immersed. If possible, dike and contain
spillage. Prevent liquid from entering sewers, sumps, or pit areas since vapor is heavier than air
and can create a suffocating atmosphere. Capture material for recycle or destruction if suitable
equipment is available.
Notify applicable government authority if release is reportable or could adversely affect the
environment.
7. HANDLING AND STORAGE
Handling: Wear appropriate personal protective equipment. A safety shower and eyewash
station should be nearby and ready for use.
This product is a liquefied gas, which exits the container at temperatures capable of causing
freeze burns (frostbite). Ensure personnel are trained in handling and storing cylinders.
Secure containers at all times. Keep containers closed when not in use.
Ensure there is adequate ventilation or use proper respiratory protection in poorly ventilated
or confined areas. Avoid causing and inhaling high concentrations of vapor. Atmospheric
levels should be controlled to below the occupational exposure limit and kept as low as
practicable.
Prevent liquid or vapor from entering sumps or sewers since vapor is heavier than air and
may form suffocating atmospheres.
Do not put mixtures of HFC-134a with air or oxygen under pressure; do not use such
mixtures for leak or pressure testing.
Do not heat containers.
Liquid transfers between containers may generate static electricity. Ensure adequate
grounding.

Avoid trapping liquid between closed valves or overfilling containers as high pressures can
develop with an increase in temperature.
Avoid HFC-134a contact with flames or very hot surfaces.
Storage Requirements: Keep containers tightly closed, in a cool, well-ventilated place.
Keep containers dry. Keep away from incompatibles, open flames, hot surfaces, welding
operations, and other heat sources.
Storage Temperature: Store at temperature not exceeding 125°F. (52°C.).
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
EXPOSURE GUIDELINES:
INGREDIENT NAME: 1,1,1,2-Tetrafluoroethane
Mexichem Fluor Guideline 1000 ppm 8 hour TWA
WEEL (AIHA) 1000 ppm 8 hour TWA
No ACGIH TLV or OSHA PEL established.
Minimize exposure in accordance with good hygiene practice.
PREVENTIVE MEASURES:
Engineering Controls: Use ventilation to maintain safe levels. Where appropriate
engineering controls are not in place or are inadequate, wear suitable respiratory equipment.
PERSONAL PROTECTIVE EQUIPMENT:
Eye Protection: Use chemical safety goggles or safety glasses and a face shield when
there is potential for eye contact.
Skin Protection: Take all precautions to prevent skin contact. Use gloves and protective
clothing made of material that has been found by user to be impervious under conditions of
use to prevent the skin from becoming frozen from contact with liquid. User should verify
impermeability under normal conditions of use prior to general use. Additional protection
such as an apron, arm covers, or full body suit may be needed depending on conditions of
use.
Respiratory Protection: Not normally needed if controls are adequate. If needed, use
NIOSH/MSHA approved respirator for organic vapors. For high concentrations and oxygendeficient atmospheres, use positive pressure air-supplied respirator.
Other Protection: Shower and eye wash station.

No effect of any kind was seen in a 90-day inhalation study in the rat at dose levels up to, and
including 50,000 ppm (6 hours per day, 5 days per week).
No developmental effects were seen in the rabbit following inhalation exposure to 40,000 ppm
during gestation despite slight maternal toxicity. In a range-finding study in the rabbit, possible
minimal embryo lethality was seen at a dose level of 50,000 ppm. In the rat, slight fetotoxicity
was present at an inhalation dose of 50,000 ppm administered during gestation and no effects
were seen at 10,000 ppm. In another study in the rat, no developmental effects were seen at a
dose of 100,000 ppm in the presence of slight maternal toxicity; clear maternal effects were
followed by embryo toxicity and fetotoxicity at a dose level of 300,000 ppm. There were no
increases in the incidence of fetal malformations in rats or rabbits at doses up to and including
300,000 ppm and 50,000 ppm, respectively.
HFC-134a showed no genetic toxicity in a range of in-vitro and in-vivo tests. No adverse effects
were found in a study in which rats were followed to week 104 after receiving 300 mg/kg
bodyweight/day of HFC-134a by gavage for 52 weeks. In a 2-year inhalation study in rats, no
adverse effects of any kind were observed except increased incidences of non-life threatening,
benign, microscopic testicular interstitial (Leydig) cell tumors and associated interstitial cell
hyperplasia which were confined to the top dose of 50,000 ppm.
