Section 3: Hazard Identification
Emergency overview
Appearance: Liquefied gas.
Immediate effects: ND
Potential health effects
Primary Routes of entry: Inhalation, eyes, skin.
Signs and Symptoms of Overexposure:
Eyes: ND
Skin: ND
Ingestion: Ingestion is not considered a potential route of exposure.
Inhalation: Inhalation of high concentrations of vapor is harmful and may cause heart irregularities, 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.
Chronic Exposure: Higher exposures may lead to irritation of nose, throat, and lungs with cough, difficulty breathing or shortness of breath, temporary alteration of the heart’s electrical activity with irregular pulse, palpitations, or inadequate circulation, or abnormal kidney function as detected by laboratory tests. Gross overexposure may be fatal.
Chemical Listed As Carcinogen Or Potential Carcinogen: 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.
See Toxicological Information (Section11)
Potential environmental effects
See Ecological Information (Section 12)
Section 4: First Aid Measures
If accidental overexposure is suspected
Eye(s) 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 medical attention if symptoms persist.
Skin Contact: 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.
Inhalation: If high concentrations are inhaled, immediately remove to fresh air. Keep person calm. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician immediately.
Ingestion: Ingestion is not considered a potential route of exposure.
Note to physician
Treatment: 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.
Medical Conditions generally Aggravated by Exposure: Individual with preexisting diseases of the central nervous, cardiovascular system, lungs, or kidneys may have increased susceptibility to the toxicity of excessive exposures.
Section 5: Fire Fighting
Measures
Flash Point: <-50 °C (<-58 °F)
Flammable Limits: 454°C (849°F)
Auto-ignition point: LEL/UEL: 3.9-16.9 (% by volume)
Fire Extinguishing Media: Water Spray, Water fog, Dry Chemical, Carbon dioxide. “Alcohol” foam.
Special Fire Fighting Procedures: Cool cans with water spray. If gas exiting can ignites, stop flow of gas. Do not put out fire unless leak can be stopped. Self-contained breathing apparatus (SCBA) is required if containers rupture and contents are released under fire conditions.
Unusual Fire and Explosion Hazards: Aerosol cans may erupt with force at temperatures above 49° C (120° F) HFC 152a fire decomposition by-products will include hydrofluoric acid, and possibly carbonyl fluoride. Avoid contact with theses materials, which are toxic and irritating. Evacuate personnel immediately in the event of a fire involving HFC-152a.
Hazardous combustion products: ND
DOT Class: Flammable Gas
Section 6: Accidental Release
Measures
Steps to be Taken in Case Material is Released or Spilled: NOTE: Review FIRE
FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with
clean-up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Although the chances of a large spill or leak are unlikely in aerosol
containers. If a spill can cause a concentration in excess of 1,000 ppm, stop
flow and remove ignition sources. Evacuate area. Ventilate area, especially low
places where heavy vapors might collect. Wear self-contained breathing
apparatus (SCBA). If
this product is spilled and not recovered, or is recovered as a waste
for treatment or disposal, the CERCLA Reportable Quantity is 100 lbs. (Release
of an unlisted Hazardous Waste characteristic of ignitability).
Waste Disposal Methods: Dispose of waste according to Federal, State and Local Regulations.
Section 7: Handling and
Storage
Precautions to be Taken in Handling and Storage: Use only with adequate
ventilation. Vapors are heavy and may concentrate in low poorly ventilated areas.
Avoid breathing vapors or mist. Keep containers closed. Avoid repeated or
prolonged contact with eyes, skin or clothing. Wash thoroughly after handling.
Do not store in direct sunlight. Store in cool dry place, away from heat,
sparks or flames which may generate toxic decomposition products.
Storage temperature: ND
Storage Pressure: ND
Section 8: Exposure Controls / Personal Protection
Engineering Controls
Ventilation required: Adequate ventilation is required.
Personal Protection Equipment
Respiratory protection: Use only with adequate ventilation. Keep container closed. Use approved NIOSH self-contained or supplied air respirators for emergencies and in situations where air may be displaced by vapors.
Protective gloves: Wear impervious gloves.
Skin protection: Where there is potential for skin contact appropriate impervious apron, pants and jacket.
Eye protection: Use chemical protective safety glasses.
Additional clothing and/or equipment: Ground all equipment and cylinders before use. Do not use near any spark producing electrical devices such as paper shredders.

Section 11: Toxicological Information
Results of component toxicity test performed: (Oral Acute ALD (Approximate Lethal Dose), Rats): >1500 mg/kg. (Inhalation ALC, Rats): 4 hr: 383,000 ppm. HFC-152a has not been tested for skin and eye irritancy, nor for animal sensitization. Ingestion of single high doses of HFC-152a caused weight loss and lethargy. Carcinogenicity: Inhalation of high levels of HFC-152a caused labored breathing, lung irritation, lethargy, loss of coordination and consciousness. Cardiac sensitization occurred in dogs exposed to a concentration of 150,000 ppm in air and given an intravenous epinephrine challenge. Repeated inhalation exposures caused increased urinary fluoride, reduced kidney weight, and reversible kidney changes. Based on an independent peer review the reversible kidney changes are considered artifacts of the tissue and slide processing and not a compound related effect. Animal testing demonstrate neither carcinogenic activity nor developmental effects. No animal data are available to define reproductive effects of HFC-152a. HFC-152a has not produced genetic damage in bacterial cultures. There are reports indicating that HFC-152a produced genetic damage in some mammalian cell culture tests. A weak genotoxic effect in germ cells of Drosophila melanogaster has been reported. It has not been tested in animals
Human experience: ND
