UM / UM PLUS Chillers and inverter air / water heat pumps with axial fans74.4 REFRIGERANT SAFETY DATA SHEETName: R410A (50% Difluoromethane (R32); 50% Pentafluoroethane (R125).RISKS INDICATIONSMajor risks: AsphyxiaSpecific risks: The rapid evaporation may cause freezing.FIRST AIDGeneral information: Never give anything by mouth to an unconscious person.Inhalation: Move to fresh air.Oxygen or artificial respiration if necessary.Do not administer adrenaline or similar drugs.Eyes contact: Rinse carefully with water for at least 15 minutes and consult a doctor.Contact with skin: Wash immediately with plenty of water.Take off immediately the contaminated clothing.FIRE PREVENTIONExtinguishing Media: Whatever.Specific risks: Increase in pressure.Specific methods: Use water spray to cool containersACCIDENTAL RELEASE ACTIONSPersonal precautions: Evacuate personnel to safe areas.Provide adequate ventilation.Use personal protective equipment.Environmental precautions: Evaporate.Cleaning method: Evaporate.HANDLING AND STORAGEManipulationAction/technical precautions: Provide sufficient air exchange and/or suction in work places.Recommendations for safe use: Do not breathe vapors or aerosol.Storage: Close tightly and store in a cool, dry and well ventilated place.Store in original container. Incompatible products: explosive, flammable materials, Organic peroxideEXPOSURE CONTROL / PERSONAL PROTECTIONControl parameters: AEL (8-h e 12-h TWA) = 1000ml/m³ for each of the two components.Respiratory protection: For rescue and maintenance operation in storage tanks use self-contained respirator apparatus.The vapors are heavier than air and can cause suffocation by reducing oxygen available for breathing.Eyes protection: Safety glasses.Protection of hands: Rubber gloves.Hygiene measures: Do not smoke.PHYSICAL AND CHEMICAL PROPERTIESColour: Colourless.Odor: Light.Boiling point: -52.8°C at atmospheric pressure.Lighting point: It does not ignite.Density: 1.08kg/l at 25°C.Solubility in water: Negligible.STABILITY AND REACTIVITYStability: No reactivity when used with the appropriate instructions.Materials to avoid: Highly oxidizing materials. Incompatible with magnesium, zinc, sodium, potassium and aluminum.The incompatibility is more serious if the metal is present in powdered form or if the surfaces were, recently,unprotected.Decomposition products These products are halogenated compounds, hydrogen fluoride, carbon oxides (CO, CO2), carbonyl halides.Risks:TOXICOLOGICAL INFORMATIONAcute toxicity: (R32) LC50/ inhalation /4 hours/on rat >760 ml/l(R125) LC50/ inhalation /4 hours/on rat >3480 mg/lLocal effects: Concentrations substantially above the TLV may cause narcotic effects.Inhalation of decomposed products of high concentrations may cause respiratory failure (pulmonary edema).Long term toxicity: Did not show carcinogenic, teratogenic or mutagenic effects in animal experiments.ECOLOGICAL INFORMATIONGlobal warming potential 1730GWP (R11=1):Potential depletion 0Ozone ODP (R11=1):Disposal considerations: usable with reconditioning. |
