CHLORODIFLUOROMETHANE (Halocarbon R22), Material Safety Data Sheet , Revision Date 25-Aug-2010,Page 2 / 9___________________________________________________________________OSHA Regulatory Status This material is considered hazardous by the OSHA Hazard Communication Standard (29 CFR1910.1200).Potential Health EffectsPrinciple Routes of ExposureInhalation. Skin contact.Acute ToxicityInhalationEyesSkinSkin Absorption HazardIngestionChronic EffectsAggravated MedicalConditionsInteractions with Other ChemicalsEnvironmental HazardHigh concentrations may cause asphyxia from lack of oxygen or act as a narcotic causing centralnervous system depression. Symptoms of overexposure are dizziness, headache, tiredness, nausea,unconsciousness, cessation of breathing. Oxygen deficiency may occur in the presence of highconcentrations resulting in asphyxiation. Maintain oxygen levels at or above 19.5%.This product is a gas at room temperature. Contact with liquid may cause frostbite.This product is a gas at room temperature. Contact with liquid may cause frostbite.No known hazard in contact with skin.Not an expected route of exposure.Possible risks of irreversible effects.Central nervous system. Cardiovascular. Heart.Use of alcoholic beverages may enhance toxic effects.See Section 12 for additional Ecological Information.3. COMPOSITION/INFORMATION ON INGREDIENTSChemical Name CAS-No Volume % Chemical FormulaChlorodifluoromethane 75-45-6 >99 CHF2Cl4. FIRST AID MEASURESGeneral AdviceEye ContactSkin ContactInhalationIngestionImmediate medical attention is required. Show this safety data sheet to the doctor in attendance.None required for gas. If frostbite is suspected, flush eyes with cool water for 15 minutes and obtainimmediate medical attention.None required for gas. For dermal contact or suspected frostbite, remove contaminated clothing andflush affected areas with lukewarm water. DO NOT USE HOT WATER. A physican should see the patientpromptly if contact with the product has resulted in blistering of the dermal surface or in deep tissuefreezing.PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF INHALATION OVEREXPOSURE. RESCUEPERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Conscious inhalationvictims should be assisted to an uncontaminated area and inhale fresh air. If breathing is difficult,administer oxygen. Unconscious persons should be moved to an uncontaminated area and, asnecessary, given artificial resuscitation and supplemental oxygen. Treatment should be symptomaticand supportive.None under normal use. Get medical attention immediately if symptoms occur.

Continue to cool fire exposed cylinders until flames areextinguished. Damaged cylinders should be handled only by specialists.As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved orequivalent) and full protective gear.6. ACCIDENTAL RELEASE MEASURESPersonal PrecautionsEnvironmental PrecautionsMethods for ContainmentMethods for Cleaning UpEnsure adequate ventilation. Evacuate personnel to safe areas. Use personal protective equipment.Monitor oxygen level.Prevent spreading of vapors through sewers, ventilation systems and confined areas.Stop the flow of gas or remove cylinder to outdoor location if this can be done without risk. If leak is incontainer or container valve, contact the appropriate emergency telephone number in Section 1 or callyour closest Linde location.Return cylinder to Linde or an authorized distributor.7. HANDLING AND STORAGEHandlingUse only in ventilated areas. Never attempt to lift a cylinder by its valve protection cap.

CHLORODIFLUOROMETHANE (Halocarbon R22), Material Safety Data Sheet , Revision Date 25-Aug-2010,Page 4 / 9___________________________________________________________________Protect cylinders from physical damage; do not drag, roll, slide or drop. When moving cylinders, evenfor short distance, use a cart designed to transport cylinders. Use equipment rated for cylinderpressure. Use backflow preventive device in piping. Never insert an object (e.g. wrench, screwdriver,pry bar,etc.) into valve cap openings. Doing so may damage valve, causing leak to occur.Use an adjustable strap wrench to remove over-tight or rusted caps. Close valve after each use andwhen empty. If user experiences any difficulty operating cylinder valve discontinue use and contactsupplier.Never put cylinders into trunks of cars or unventilated areas of passenger vehicles. Never attempt torefill a compressed gas cylinder without the owner's written consent. Never strike an arc on acompressed gas cylinder or make a cylinder a part of an electrical circuit.For additional recommendations consult Compressed Gas Association's (CGA) Safety Bulletin SB-2,Oxygen-Deficient Atmospheres.StorageProtect from physical damage. Cylinders should be stored upright with valve protection cap in placeand firmly secured to prevent falling. Store in cool, dry, well-ventilated area of non-combustibleconstruction away from heavily trafficked areas and emergency exits. Keep at temperatures below52°C / 125°F. Full and empty cylinders should be segregrated. Use a "first in-first out" inventorysystem to prevent full cylinders from being stored for excessive periods of time. Always store andhandle compressed gas cylinders in accordance with Compressed Gas Association, pamphlet CGA-P1,Safe Handling of Compressed Gases in Containers.8.
