3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW:
CAUTION! This product is a clear, colorless, liquefied gas. Contents under pressure.
Cylinders may rupture and rocket under fire conditions. Thermal decomposition can
produce toxic and corrosive gases. Vapors are heavier than air. May cause asphyxia.
Liquid splashes or spray may cause freeze burns (frostbite). High vapor concentrations
may cause dizziness or more severe anesthetic effects. Very high exposures can cause
potentially fatal abnormal heart rhythm. Read the entire MSDS for a more thorough
evaluation of the hazards.

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.
