Hazard InformationBack Directory
[General Description]

CHLORODIFLUOROMETHANE(75-45-6) is a colorless gas with an ethereal odor. CHLORODIFLUOROMETHANE(75-45-6) is shipped as a liquefied gas under its own vapor pressure. CHLORODIFLUOROMETHANE(75-45-6) is noncombustible. CHLORODIFLUOROMETHANE(75-45-6) can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite. Toxic gases can be produced in fires involving this material. Exposure of the container to prolonged heat or fire may cause CHLORODIFLUOROMETHANE(75-45-6) to rupture violently and rocket.
[Reactivity Profile]

CHLORODIFLUOROMETHANE is incompatible with the following: Alkalis, alkaline earth metals (e.g., powdered aluminum, sodium, potassium, zinc) .
[Air & Water Reactions]

The liquefied gas poured into water can be violently explosive. This is due to the phase transition from superheated liquid to vapor.
[Hazard]

Asphyxiant. Central nervous system impairment, cardiac sensitization. Questionable carcinogen.
[Health Hazard]

Inhalation at greater than 10% concentration in air may cause narcosis. Liquid may cause frostbite.
[Potential Exposure]

Chlorodifluoromethane is used as an aerosol propellant, refrigerant, and low-temperature solvent. It is used in the synthesis of polytetrafluoroethylene (PTFE).
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. If frostbite has occurred, seek medical attention immediately; do NOT rub the affected areas or flush them with water. In order to prevent further tissue damage, do NOT attempt to remove frozen clothing from frostbitten areas. If frostbite has NOT occurred, immediately and thoroughly wash contaminated skin with soap and water.
[Fire Hazard]

Special Hazards of Combustion Products: Decomposition gases are toxic and irritating.
[Shipping]

UN1018 Chlorodifluoromethane, Hazard Class: 2.2; Labels: 2.2-Non-flammable compressed gas. Cylinders must be transported in a secure upright position, in a wellventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.
[Incompatibilities]

The liquefied gas poured into water can be violently explosive. This is due to the phase transition from superheated liquid to vapor. Chlorodifluoromethane reacts violently with alkalies and alkaline earth metals; powdered aluminum; sodium, potassium, and zinc; causing fire and explosion hazard. Moisture and rust cause slow decomposition, forming toxic gases. Attacks some plastics, rubber, and coatings. Decomposes in heat forming fumes of chlorine, hydrogen chloride, HF, and phosgene. Attacks magnesium and its alloys.
[Waste Disposal]

Return refillable compressed gas cylinders to supplier. Return to vendor or send to licensed waste disposal company.
[Chemical Properties]

colourless gas
[Chemical Properties]

Chlorodifluoromethane is a nonflammable, colorless, nearly odorless gas.
[Carcinogenicity]

In one study, an oral dose of 300mg of HCFC 22/kg of body weight was given to 36 male and 36 female rats 5 days/week for 52 weeks. The rats were held for 125 weeks compared to controls. There was no evidence of any treatment related increase in tumors. In an inhalation study 60 male and 60 female rats were exposed by inhalation to levels of 5000 ppm of HCFC 22. The exposures were 4 h/day, 5 days/week for 104 weeks (rats) or 78 weeks (mice).
