The Uses of DIBROMODIFLUOROMETHANE

Fire-extinguishing agent

General Description

DIBROMODIFLUOROMETHANE is a colorless, nonflammable liquid. DIBROMODIFLUOROMETHANE may cause illness from ingestion and may be irritating to skin. If exposed to high temperatures DIBROMODIFLUOROMETHANE may emit toxic fumes. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since DIBROMODIFLUOROMETHANE is a liquid DIBROMODIFLUOROMETHANE can easily penetrate the soil and contaminate groundwater and nearby streams. DIBROMODIFLUOROMETHANE is used as a fire extinguishing agent.

Reactivity Profile

DIBROMODIFLUOROMETHANE is incompatible with the following: Chemically-active metals such as sodium, potassium, calcium, powdered aluminum, zinc & magnesium .

Health Hazard

Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution.

Fire Hazard

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

Safety Profile

Mddly toxic by inhalation. A non-flammable liquid. When heated to decomposition it emits very toxic fumes of Brand F-

Potential Exposure

This material is used as a fire-extinguishing agent and in making dyes and pharmaceuticals.

First aid

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.

storage

Color Code—Green: General storage may be used.Difluorodibromomethane must be stored to avoid contactwith chemically active metals, such as sodium, potassium,calcium, powdered aluminum, zinc, and magnesium sinceviolent reactions occur. Store in tightly closed containers in acool, well-ventilated area away from heat.

Shipping

This compound does not require a shipping label.It falls in Hazard Class 9 and Packing III. The symbol “A”restricts the application of requirements of this subchapterto materials offered or intended for transportation by aircraft, unless the material is a hazardous substance or a hazardous waste.

Incompatibilities
