Gas reduces oxygen available for breathing. Contact with liquid or refrigerated gas can cause cold burns and frostbite. Protection of first-aiders : No special precautions are necessary for first aid responders. Notes to physician : Because of possible disturbances of cardiac rhythm, ca- techolamine drugs, such as epinephrine, that may be used in situations of emergency life support should be used with spe- cial caution. SECTION 5. FIRE-FIGHTING MEASURES Suitable extinguishing media : Not applicable Will not burn Unsuitable extinguishing media : Not applicable Will not burn Specific hazards during fire fighting : Exposure to combustion products may be a hazard to health. If the temperature rises there is danger of the vessels bursting due to the high vapor pressure. Hazardous combustion prod- ucts : Hydrogen fluoride carbonyl fluoride Carbon oxides Specific extinguishing meth- ods : Use extinguishing measures that are appropriate to local cir- cumstances and the surrounding environment. Fight fire remotely due to the risk of explosion. Use water spray to cool unopened containers. Remove undamaged containers from fire area if it is safe to do so. Evacuate area. Special protective equipment for fire-fighters : Wear self-contained breathing apparatus for firefighting if necessary. Use personal protective equipment. SECTION 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protec- tive equipment and emer- gency procedures : Evacuate personnel to safe areas. Avoid skin contact with leaking liquid (danger of frostbite). Ventilate the area. Follow safe handling advice (see section 7) and personal pro- tective equipment recommendations (see section 8). Environmental precautions : Avoid release to the environment. Prevent further leakage or spillage if safe to do so. Retain and dispose of contaminated wash water.

Local or national regulations may apply to releases and dispo- sal of this material, as well as those materials and items em- ployed in the cleanup of releases. You will need to determine which regulations are applicable. Sections 13 and 15 of this SDS provide information regarding certain local or national requirements. SECTION 7. HANDLING AND STORAGE Technical measures : Use equipment rated for cylinder pressure. Use a backflow preventative device in piping. Close valve after each use and when empty. Local/Total ventilation : Use only with adequate ventilation. Advice on safe handling : Avoid breathing gas. Handle in accordance with good industrial hygiene and safety practice, based on the results of the workplace exposure as- sessment Wear cold insulating gloves/ face shield/ eye protection. Valve protection caps and valve outlet threaded plugs must remain in place unless container is secured with valve outlet piped to use point. Prevent backflow into the gas tank. Use a check valve or trap in the discharge line to prevent ha- zardous back flow into the cylinder. Use a pressure reducing regulator when connecting cylinder to lower pressure (<3000 psig) piping or systems. Close valve after each use and when empty. Do NOT change or force fit connections. Prevent the intrusion of water into the gas tank. Never attempt to lift cylinder by its cap. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Keep away from heat and sources of ignition. Take precautionary measures against static discharges. Take care to prevent spills, waste and minimize release to the environment. Conditions for safe storage : Cylinders should be stored upright and firmly secured to pre- vent falling or being knocked over. Separate full containers from empty containers. Do not store near combustible materials. Avoid area where salt or other corrosive materials are present. Keep in properly labeled containers. Keep in a cool, well-ventilated place. Keep away from direct sunlight. Store in accordance with the particular national regulations. Materials to avoid : Do not store with the following product types: Self-reactive substances and mixtures SAFETY DATA SHEET according to the Hazardous Products Regulations Freon? 134a Auto (HFC-134a) Refrigerant Version 8.11 Revision Date: 12/11/2023 SDS Number: 1329602-00047 Date of last issue: 04/21/2023 Date of first issue: 02/27/2017 5 / 14 Organic peroxides Oxidizing agents Flammable liquids Flammable solids Pyrophoric liquids Pyrophoric solids Self-heating substances and mixtures Substances and mixtures which in contact with water emit flammable gases Explosives Very acutely toxic substances and mixtures Acutely toxic substances and mixtures Substances and mixtures with chronic toxicity Recommended storage tem- perature : < 52 ?C Storage period : > 10 y Further information on stor- age stability : The product has an indefinite shelf life when stored properly. SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Ingredients with workplace control parameters Contains no substances with occupational exposure limit values. Engineering measures : Ensure adequate ventilation, especially in confined areas. Minimize workplace exposure concentrations. Personal protective equipment Respiratory protection : If adequate local exhaust ventilation is not available or expo- sure assessment demonstrates exposures outside the re- commended guidelines, use respiratory protection. Filter type : Organic gas and low boiling vapor type Hand protection Material : Low temperature resistant gloves Remarks : Choose gloves to protect hands against chemicals depending on the concentration specific to place of work. For special applications, we recommend clarifying the resistance to che- micals of the aforementioned protective gloves with the glove manufacturer. Wash hands before breaks and at the end of workday. Breakthrough time is not determined for the pro- duct. Change gloves often! Eye protection : Wear the following personal protective equipment: Chemical resistant goggles must be worn.

Follow precautionary advice and avoid incompatible materials and conditions. Possibility of hazardous reac- tions : Can react with strong oxidizing agents. Conditions to avoid : This substance is not flammable in air at temperatures up to 100 ?C (212 ?F) at atmospheric pressure. However, mixtures of this substance with high concentrations of air at elevated pressure and/or temperature can become combustible in the presence of an ignition source. This substance can also be- come combustible in an oxygen enriched environment (oxy- gen concentrations greater than that in air). Whether a mixture containing this substance and air, or this substance in an oxy- gen enriched atmosphere become combustible depends on the inter-relationship of 1) the temperature 2) the pressure, and 3) the proportion of oxygen in the mixture. In general, this substance should not be allowed to exist with air above at- mospheric pressure or at high temperatures; or in an oxygen enriched environment. For example this substance should NOT be mixed with air under pressure for leak testing or other SAFETY DATA SHEET according to the Hazardous Products Regulations Freon? 134a Auto (HFC-134a) Refrigerant Version 8.11 Revision Date: 12/11/2023 SDS Number: 1329602-00047 Date of last issue: 04/21/2023 Date of first issue: 02/27/2017 8 / 14 purposes.
