Material safety data sheet r22 äº�æ°�ä¸�æ°¯ç�²ç�· date: april 2011 1 product and company identification product identification product name r22 chemical formula ch cl f2 trade name r22 2 composition/information on ingredients chemical names: chlorodifluoromethane chemical family chlorofluorocarbon cas no. 75-45-6 un no. 1018 erg no 126 hazchem warning 2c non-flammable gas 3 hazards identification main hazards all cylinders are portable gas containers, and must be regarded as pressure vessels at all times. R22 does not support life. It can act as a simple asphyxiant by diluting the concentration of oxygen in air to below the levels necessary to support life. Adverse contains a liquefied gas. Contact with liquid health effects may cause frostbite and injury to the cornea. Chemical heating will cause a rise in pressure with a risk hazards of bursting. On combustion, toxic gases are released. Biological contact with the liquid phase could cause hazards freeze burns. 4 first aid measures prompt medical attention is mandatory in all cases of overexposure to vaporised r22. Rescue personnel should be equipped with self-contained breathing apparatus. Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. Unconscious persons should be removed to an uncontaminated area and given mouth-to-mouth resuscitation and supplemental oxygen. The use of adrenaline or similar drugs should be avoided. Eye contact (vapour) no known effect. (liquid) immediately flush with large quantities of tepid water, or with sterile saline solution. Seek medical attention. Skin contact (vapour) no known effect. (liquid) in case of frostbite from contact with liquid r22, place the frost-bitten part in warm water, about 40-42â°c. If warm water is not available, or is impractical to use, wrap the affected part gently in blankets. Encourage the patient to exercise the affected part whilst it is being warmed. Do not remove clothing whilst frosted. Ingestion provided the patient is conscious, wash out the mouth with water, and give 200-300 ml to drink. Obtain immediate medical attention. 5 fire fighting measures extinguishing as r22 is non-flammable, it will not media contribute to the fire, but could help with the extinguishing by reducing the oxygen content of the air by dilution to below the level to support combustion. If possible shut off the source of r22. Evacuate area. All cylinders should be removed from the vicinity of the fire. Cylinders that cannot be removed should be cooled with water from a safe distance. Cylinders which have been exposed to excessive heat should be clearly identified for inspection. Specific pressurised container. On heating there is a risk hazards of bursting due to internal pressure build-up not flammable. However, it may present a risk in the event of fire. Toxic vapours (halogen compounds ) are released. Vapour / air mixture may be flammable under specific conditions. Protective self-contained breathing apparatus. Safety gloves clothing and shoes, or boots, should be worn when handling cylinders. Environmental precautions. Care should be taken when entering a potentially oxygen-deficient environment. If possible, ventilate the affected area. 6 accidental release measures personal precautions. Do not enter any areas where r22 has been spilled unless tests have shown that it is safe to do so. Environmental prevent the product from spreading into the precautions environment. Contain the spilled material by bunding. Small spills shut off source of the r22. Ventilate the area. Large spills evacuate the area. Shut off the source of the spill if this can be done without risk. Restrict access to the area until completion of the clean-up procedure. Ventilate the area using forced-draught if necessary. 7 handling and storage do not allow cylinders to slide or come into contact with sharp edges. R22 cylinders should be stacked vertically at all times, and should be firmly secured in order to prevent them from being knocked over. Use a â��first in - first out?inventory system to prevent full cylinders from being stored for excessive periods of time. Keep out of reach of children. 8 exposure controls/personal protection occupational exposure hazards as r22 is a simple asphyxiant, avoid any areas where spillage has taken place. Only enter once testing has proved the atmosphere to be safe, and remember that the gas is heavier than air. Engineering control measures. Engineering control measures are preferred to reduce exposure to oxygen depleted atmospheres. General methods include forced-draught ventilation, separate from other exhaust ventilation systems. Ensure that sufficient fresh air enters at, or near, floor level. Personal protection self-contained breathing apparatus should always be worn when entering area where oxygen depletion may have occurred. Safety goggles, gloves and shoes or boots should be worn when handling cylinders.

Never expose the cylinders to excessive heat, as this may cause sufficient build-up of pressure to rupture the cylinders. Incompatible since the performance of plastic materials is materials affected by polymer variations, compounding agents, fillers, and moulding processes, verify compatibility using actual fabricated parts under end-use conditions. The effects on specific elastomers depend on the nature of the polymer, the compounding formulation used and the curing of vulcanizing conditions. Actual samples should be tested under end-use conditions before specifying elastomers for critical components. Hazardous decomposition products. R22 vapours will decompose when exposed to high temperatures from flames or electric resistance heaters. Decomposition may produce toxic and irritating compounds, such as hydrogen fluoride. 11 toxicological information acute toxicity (twa 8+12 hr) 1000 ppm skin & eye contact no known effect chronic toxicity no known effect carcinogenicity no known effect mutagenicity no known effect reproductive hazards no known effect (for further information see section 3.
