Carbonyl fluoride is colorless or light yellow, hygroscopic, compressed liquefied gas. Pungent, highly irritating and suffocating odor.

A colorless gas with a pungent odor. Very toxic by inhalation. Prolonged exposure of the containers to fire or heat may result in violent rupturing and rocketing.

Reacts with water or steam to produces corrosive and toxic hydrofluoric acid fumes.

CARBONYL FLUORIDE is an acid fluoride. Incompatible with water, with bases (including amines), with strong oxidizing agents, with alcohols. Reacts violently with hexafluoroisopropylideneaminolithium. High temperature causes decomposition to toxic carbon monoxide gas and fluorine. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Irritates lungs, causing delayed pulmonary edema. Slight gassing produces dryness or burning sensation in the throat, numbness, pain in the chest, bronchitis, and shortness of breath.

Special Hazards of Combustion Products: Toxic gas is generated when heated.

Toxic by inhalation, strong irritant to skin. Lower respiratory tract irritant. Bone damage.

Carbonyl fluoride is a carboxy halide. The major source of exposure to COF2 results from the thermal decomposition of fluoro carbon plastics, such as PTFE in air. Carbonyl fluoride is used for synthesizing fluoroalkanes, difluoroisocyanates, and fluorinated alkyl isocyanates. It may have been used as a military poison gas.

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. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. 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

UN2417 Carbonyl fluoride, Hazard class: 2.3; Labels: 2.3-Poisonous gas, 8-Corrosive material, Inhalation Hazard Zone B. Cylinders must be transported in a secure upright position, in a well-ventilated 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.

Reacts with water to form toxic and corrosive HF gas. HF gas is highly reactive and forms explosive hydrogen gas on contact with metals. Do not use cast iron or malleable fittings with carbonyl fluoride. Carbonyl fluoride decomposes on heating above 450C producing toxic gases, including HF. Not compatible with hexafluoroisopropylidene-amino lithium; reaction may be dangerous.

Return refillable compressed gas cylinders to supplier.

Colorless gas; pungent odor; hygroscopic; unstable; liquid density 1.139 g/mL (at -114°C); liquefies at -83.1°C; solidifies at -114°C; decomposes in water.

Carbonyl fluoride is prepared by the reaction of carbon monoxide with fluorine gas or silver fluoride:
CO + F₂ → COF₂
Also, it may be produced by the action of carbon monoxide with bromine trifluoride, BrF₃.

Color Code—White stripe: Contact Hazard; Storeseparately; not compatible with materials in solid white category. Storage area must be absolutely dry.
