HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW: Colorless, volatile liquid with 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,
(>250°C), decomposition products may include Hydrofluoric Acid (HF) and carbonyl halides.
POTENTIAL HEALTH HAZARDS
SKIN: Irritation would result from a defatting action on tissue. Liquid contact could cause frostbite.
EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate.
INHALATION: R-134A is low in 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.
INGESTION:
Ingestion is unlikely because of the low boiling point of the material. Should it occur, discomfort in the
gastrointestinal tract from rapid evaporation of the material and consequent evolution of gas would result.
Some effects of inhalation and skin exposure would be expected.
DELAYED EFFECTS: None Known

FIRST AID MEASURES
SKIN: Promptly flush skin with water until all chemical is removed. If there is evidence of frostbite, bathe (do not rub) with
lukewarm (not hot) water. If water is not available, cover with a clean, soft cloth or similar covering. Get medical attention
if symptoms persist.
EYES: 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 medical attention if symptoms persist.
INHALATION: Immediately remove to fresh air. If breathing has stopped, give artificial respiration. Use oxygen as
required, provided a qualified operator is available. Get medical attention immediately. DO NOT give epinephrine
(adrenaline).
INGESTION:
Ingestion is unlikely because of the physical properties and is not expected to be hazardous. DO NOT induce
vomiting unless instructed to do so by a physician.
ADVICE TO PHYSICIAN: Because of the possible disturbances of cardiac rhythm, catecholamine drugs, such as
epinephrine, should be used with special caution and only in situations of emergency life support.
Treatment of overexposure should be directed at the control of symptoms and the clinical
conditions.

UNUSUAL FIRE AND EXPLOSION HAZARDS:
R-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 formation of explosive or exothermic reactions under specific conditions
(e.g. very high temperatures and/or appropriate pressures).

SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:
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.
6.
ACCIDENTAL RELEASE MEASURES
IN CASE OF SPILL OR OTHER RELEASE:
(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 air has been tested and determined safe, including lowlying areas.
Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding reporting
requirements.
7.
HANDLING AND STORAGE
NORMAL HANDLING:
(Always wear recommended personal protective equipment.)
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
compressed gas cylinders.
R-134A should not be mixed with air above atmospheric pressure for leak testing or any other purpose.
STORAGE RECOMMENDATIONS:
Store in a cool, well-ventilated area of low fire 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.
8.
EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS:
Provide local ventilation at filling zones and areas where leakage is probable. Mechanical (general) ventilation may be
adequate for other operating and storage areas.
PERSONAL PROTECTIVE EQUIPMENT
SKIN PROTECTION:
Skin contact with refrigerant may cause frostbite. General work clothing and gloves (leather) should provide
adequate protection. If prolonged contact with liquid or gas is anticipated, insulated gloves constructed of PVA,
neoprene or butyl rubber should be used. Any contaminated clothing should be promptly removed and washed
before reuse.
EYE PROTECTION:
For normal conditions, wear safety glasses. Where there is reasonable probability of liquid contact, wear chemical
safety goggles.

RESPIRATORY PROTECTION:
None generally required for adequately ventilated work situations. For accidental release or non-ventilated
situations, or release into confined space, where the concentration may be above the PEL of 1,000 ppm, use a selfcontained, NIOSH approved breathing apparatus or supplied air respirator. For escape: use the former or a NIOSH
approved gas mask with organic vapor canister.
ADDITIONAL RECOMMENDATIONS:
Where contact with liquid is likely, such as in a spill or leak, impervious boots and clothing should be worn. High
dose-level warning signs are recommended for areas of principle exposure. Provide eyewash stations and quickdrench shower facilities at convenient locations. For tank cleaning operations, see OSHA regulations, 29 CFR
1910.132 and 29 CFR 1910.133.
