Chlorodifluorobromomethane is a colorless gas or liquid under pressure.

BROMOCHLORODIFLUOROMETHANE is used as a refrigerant, a highly efficient fire extinguishing agent, and a metal surface lubricant. It is also used as rocket fuel and a protective agent for aircraft generators.

ChEBI: A one-carbon compound that is methane in which the hydrogens have been replaced by two fluorines, a bromine, and a chlorine. Widely used in 'vapourising liquid'-type fire extinguishers, its use is now generally banned under the Montreal Protocol (ozone-dep eting substances), although it is still used in certain applications (e.g. aviation).

BROMOCHLORODIFLUOROMETHANE is a colorless, nonflammable gas. BROMOCHLORODIFLUOROMETHANE is mildly toxic by inhalation. BROMOCHLORODIFLUOROMETHANE can asphyxiate by the displacement of air. Exposure of the container to prolonged heat or fire may cause BROMOCHLORODIFLUOROMETHANE to rupture violently and rocket. BROMOCHLORODIFLUOROMETHANE is used as a refrigerant gas.

BROMOCHLORODIFLUOROMETHANE is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. Can react with strong oxidizing agents or weaker oxidizing agents under extremes of temperature.

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.

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

Mutation data reported. An asphyxiant. See also ARGON for description of inert gas asphyxiants. When heated to decomposition it emits very toxic fumes of Br-, Cl-, and F-

Used as a refrigerant and fire extinguishing agent.

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. Iffrostbite has occurred, seek medical attention immediately;do NOT rub the affected areas or flush them with water. Inorder to prevent further tissue damage, do NOT attempt toremove frozen clothing from frostbitten areas. If frostbitehas NOT occurred, immediately and thoroughly wash contaminated skin with soap and water.

Nonflammable gas. Color Code—Green: Generalstorage may be used. Prior to working with this chemicalyou should be trained on its proper handling and storage.Before entering confined space where this chemical maybe present, check to make sure sufficient oxygen (19%)exists. Store in tightly closed containers in a cool, wellventilated area away from heat and sparks. Procedures forthe handling, use, and storage of cylinders should be incompliance with OSHA 1910.101 and 1910.169, as withthe recommendations of the Compressed Gas Association.

UN1974 Chlorodifluorobromomethane or Refrigerant gas R-12B1, Hazard Class: 2.2; Labels: 2.2- Nonflammable compressed 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.

The liquefied gas poured into water may be violently explosive. This is due to the phase transition from superheated liquid to vapor. Chlorodifluorobromomethane is generally chemically inert; however, it can react violently with strong reducing agents such as hydrides and highly active metals. It will react with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides strong oxidizing agents. It can also react with weak oxidizers under extreme temperatures.
