75-63-8

A colorless, odorless gas at room conditions Shipped as a liquid confined under its own vapor pressure. Noncombustible. Nontoxic but can asphyxiate by the displacement of air. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Exposure of the container to prolonged heat or fire can cause BROMOTRIFLUOROMETHANE(75-63-8) to rupture violently and rocket.

BROMOTRIFLUOROMETHANE may react with aluminum to produce substantial heat. Other halogenated hydrocarbons, such as fluorotrichloromethane, dichlorodifluoromethane, chlorodifluoromethane, tetrafluoromethane produce sufficient heat in this way to melt aluminum pieces. The vigor of the reaction appears to depend on the degree of fluorination and the vapor pressure [Chem. Eng. News 39(27):44 1961].

Slightly soluble in water.

Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.

This material is used as a fire extinguishing agent, a chemical intermediate, and as a refrigerant.

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

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.

UN1009 Bromotrifluoromethane or Refrigerant gas, R-13B, Hazard Class: 2.2; Labels: 2.2-Nonflammable gas. 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.

Keep away from chemically active metals, such as calcium, powdered aluminum; zinc, magnesium. Attacks some plastics, rubber, and coatings.

Trifluorobromomethane is a colorless gas with a slight ethereal odor. Shipped as a liquefied compressed gas.

Return refillable compressed gas cylinders to supplier. Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced.

Fire extinguishing agent; refrigerant.

Used as fire extinguishing agent for oil, electrical equipment, organic solvent, natural gas and a variety of organics, especially for important military and civilian sites.

Purify the gas by passing it through a tube containing P2O5 on glass wool into a vacuum system where it is frozen out in a quartz tube and degassed by a cycles of freezing, evacuating and thawing. [Beilstein 1 III 83, 1 IV 73.]
