6 R-502 R-502 Safety Data Sheet 1. CHEMICAL PRODUCT AND COMPANY IDENTIFICATION PRODUCT NAME: R-502 OTHER NAME:. Chlorodifluoromethane, Chloropentafluoroethane USE: Refrigerant Gas DISTRIBUTOR: National Refrigerants, Inc. 661 Kenyon Avenue Bridgeton, New Jersey FOR MORE INFORMATION CALL: IN CASE OF EMERGENCY CALL: (Monday-Friday, 8:00am-5:00pm) CHEMTREC: HAZARDS IDENTIFICATION CLASSIFICATION: SIGNAL WORD: HAZARD STATEMENT: SYMBOL: PRECAUTIONARY STATEMENT: Gases under pressure, Liquefied Gas WARNING Contains gas under pressure, may explode if heated Gas Cylinder STORAGE: Protect from sunlight, store in a well ventilated place 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 Hydrochloric acid (HCI), 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-502 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 Ingredients found on one of the OSHA designated carcinogen lists are listed below.

UNUSUAL FIRE AND EXPLOSION HAZARDS: MSDS: R-502 Page 2 of 7 Current Issue Date: April 2015

8 R-502 R-502 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-502 should not be mixed with air above atmospheric pressure for leak testing or any other purpose. See Section 5: Unusual Fire and Explosion Hazards 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. INCOMPATABILITIES: Freshly abraded aluminum surfaces at specific temperatures and pressures may cause a stron exothermic reaction. Chemically reactive metals: potassium, calcium, powdered aluminum, magnesium, and zinc. 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, MSDS: R-502 Page 3 of 7 Current Issue Date: April 2015

9 R-502 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.
