If the temperature rises there is danger of the vessels bursting due to the high vapor pressure. Hazardous combustion prod- ucts : Hydrogen fluoride Fluorine compounds 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. Leaking gas fire: Do not extinguish, unless leak can be stopped safely. 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.

Follow safe handling advice and personal protective equipment recommendations. Environmental precautions : Prevent further leakage or spillage if safe to do so. Retain and dispose of contaminated wash water. Methods and materials for containment and cleaning up : Ventilate the area. Non-sparking tools should be used. Suppress (knock down) gases/vapors/mists with a water spray jet. 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 : If sufficient ventilation is unavailable, use with local exhaust ventilation. If advised by assessment of the local exposure potential, use only in an area equipped with explosion-proof exhaust ventila- tion. 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 Keep container tightly closed. 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. Use a check valve or trap in the discharge line to prevent ha- zardous back flow into the cylinder. Prevent backflow into the gas tank. 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.

YF (R-1234yf) Refrigerant Version 8.2 Revision Date: 10/10/2019 SDS Number: 1335696-00044 Date of last issue: 03/26/2019 Date of first issue: 02/27/2017 6 / 15 Personal protective equipment Respiratory protection : General and local exhaust ventilation is recommended to maintain vapor exposures below recommended limits. Where concentrations are above recommended limits or are unknown, appropriate respiratory protection should be worn. Follow OSHA respirator regulations (29 CFR 1910.134) and use NIOSH/MSHA approved respirators. Protection provided by air purifying respirators against exposure to any hazar- dous chemical is limited. Use a positive pressure air supplied respirator if there is any potential for uncontrolled release, exposure levels are unknown, or any other circumstance where air purifying respirators may not provide adequate protection. 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. Face-shield Skin and body protection : Wear the following personal protective equipment: If assessment demonstrates that there is a risk of explosive atmospheres or flash fires, use flame retardant antistatic protective clothing. Protective measures : Wear cold insulating gloves/ face shield/ eye protection. Hygiene measures : If exposure to chemical is likely during typical use, provide eye flushing systems and safety showers close to the wor- king place. When using do not eat, drink or smoke. Wash contaminated clothing before re-use. SECTION 9. PHYSICAL AND CHEMICAL PROPERTIES Appearance : Liquefied gas Color : colorless, clear Odor : slight, ether-like SAFETY DATA SHEET Opteon?
