Keep containers dry. Keep away from direct sunlight, heat and sources of ignition. Handling: Avoid causing and inhaling high concentrations of vapor. Atmospheeric levels should be controlled to below the occupational exposure limit and kept as low as practicable.

Autoignition: Not applicable. Flammable limits (STF): Nonflammable. General Hazards: Compressed liquefied gas. Heavy vapors can suffocate. HFC 134a is not flammable in air under ambient conditions of temperature and pressure, certain HFC 134a/air mixtures were shown to be flammable. Mixtures of HFC 134a and air or oxygen should not be used for pressure or leak testing. Certain mixtures of HFC134a and chlorine may be flammable under some conditions. Thermal decomposition will evolve toxic and irritant vapors. Fire Fighting Instructions: Not applicable. Use media suitable for surrounding fire. Use water spray to cool containers. Fire Fighting Equipment: Self-contained breathing apparatus with full facepiece and protective clothing. Hazardous combustion products: Highly toxic decomposition products. SECTION 6 — REACTIVITY DATA Stability: Stable under normal conditions. Incompatibility: Finely divided metals, magnesium and alloys containing more than 2% magnesium. Can react violently if in contact with alkali or alkali earth metals such as sodium, potassium or barium. Hazardous Decomposition Products: Hydrogen fluoride by thermal decomposition and hydrolysis.. Hazardous Polymerization: Will not occur SECTION 7 — HEALTH HAZARD DATA Emergency Overview: Appearance: Colorless liquidfied gas with faint ethereal odor. Physical hazards* Compressed liquefied gas Health hazards Harmful (central nervous system depression, cardiac arrhythmias) *Hazard summary (as defined by OSHA Hazard Comm. Std., 29 CFR 1910.1200): Potential Health Effects: General: The health hazard assessment is based on toxicity studies together with information from a search of the scientific literature and other commercial sources. EYES: Liquid splashes or vapor spray may cause freeze burns. INGESTION: Extremely unlikely to occur in use. Labconco MSDS Sheet 10303, Rev A, ECO A883 7/25/01 3 of 5 INHALATION: Exposure to very high vapor concentrations can induce anesthetic effects progressing from dizziness, weakness, nausea, to unconsciousness. It can act as an asphyxiant by limiting available oxygen. At very high doses, cardiac sensitization to circulate epinephrine-like compounds can result in fatal cardiac arrhythmias. SKIN: This product will probably not be absorbed through human skin. Other effects of exposure: None expected. FIRST AIR PROCEDURES EYES: Immediately flush with plenty of water. After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes. Have eyes examined and treated by medical personnel. INHALATION: Remove victim to fresh air. Keep warm and at rest. If not breathing, give artificial respiration, preferably mouth-to-mouth. If breathing is labored, give oxygen. In the event of cardiac arrest, apply external cardiac massage. Do not administer adrenaline or similar sympathomimetic drugs as cardiac arrhythmias may result. Get immediate medical attention. INGESTION: Not applicable SKIN: Thaw affected area with water. Remove contaminated clothing. CAUTION: Clothing may adhere to the skin in the case of freeze burns. After contact with skin, wash immediately with plenty of warm water. If symptoms (irritation or blistering) develop, get medical attention. SECTION 8 — SPILL OR LEAK PROCEDURES Accidental release measures: Precautions should take into account the severity of the leak or spill. For large releases; Use recommended personal protection and evaluate unprotected personnel. Shut off leak if without risk. Ventilate the spill area. If possible, dike and contain spillage. Prevent liquid from entering sewers, sumps or pit areas, since vapor can create suffocating atmosphere. Capture material for recycle or destruction if suitable equipment is available. SECTION 9 — SPECIAL PROTECTION INFORMATION Respiratory Protection: Not normally needed, if controls are adequate. If needed, use MSHA- NIOSH approved respirator for organic vapors. For high concentrations and oxygen-defecient atmospheres, use positive pressure air-supplied respirator. Exposure guidelines: No ACGIH TLV or OSHA PEL assigned. WEEL (AIHA): 1,000 ppm 8 hr TWA. Minimize exposure in accordance with good hygiene practice. INEOS FLUOR has established an occupational exposure limit of 1,000 ppm (8 hr TWA) for this material. Labconco MSDS Sheet 10303, Rev A, ECO A883 7/25/01 4 of 5 Protective Clothing: Impervious gloves if any possibility of skin contact with the liquid. Additional protection may be required such as apron, arm covers, or full body suit, depending upon conditions. Engineering Controls: Ventilate low-lying areas such as sumps or pits where dense vapors collect. Use ventilation adequate to maintain safe levels. Provide eyewash station in work area. Eye Protection: Chemical tight goggles, full face shield in addition if splashing is possible. SECTION 10 — TOXICOLOGICAL INFORMATION Possible Human Health Effects: Inhalation: High atmospheric concentrations may lead to anesthetic effects, including loss of consciousness. Very high exposures may cause an abnormal heart rhythm and prove suddenly fatal. Higher concentrations may cause asphyxiation due to reduced oxygen content of the atmosphere. Skin Contact: Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorption. Eye Contact Liquid splashes or spray may cause freeze burns. Ingestion: Highly unlikely, but should this occur, freeze burns will result. Animal data: The inhalation 4 hour LC50 in rats was greater than 500,000 ppm HFC 134a. Slight eye irritation resulted from a brief spray of vapor. The material was a slight skin irritant, but not a skin sensitizer. The threshold for cardiac sensitization (arrhythmias) in dogs pretreated with epinephrine was an atmosphere of 75,000 ppm. The no observed effect level (NOEL) was 50,000 ppm. SECTION 11 — ECOLOGICAL INFORMATION Persistence and degradation: Decomposes comparatively rapidly in the lower atmosphere (troposphere). Atmospheric lifetime is 15.6 years. Products of decomposition will be highly dispersed and hence will have a very low concentration. It is not a significant contributor to photochemical smog and is not considered to be a VOC. Is not considered an ozone depleting chemical. Effective on effluent treatment: - Discharges of the product will enter the atmosphere and will not result in long term aqueous contamination. SECTION 12 — DISPOSAL CONSIDERATIONS Disposal method: Discarded product is not a hazardous waste under RCRA, 40 CFR261. However, HFC134a should be recycled, reclaimed or destroyed whenever possible. Container Disposal: For disposable (DOT 39) cylinders only. Do not distribute, make available, furnish or reuse empty container when once emptied of the original product. Open valve to remove pressure in the cylinder. Then puncture, drill, crush or otherwise destroy empty cylinder and dispose of in a facility permitted for nonhazardous waste. Refrigeration application: Subject to no venting regulations of Sections 608 and 609 of the Clean Air Act during the service or disposal of equipment.
