Hazard Information

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.
