| Hazard Information | Back Directory | [General Description]
A dense liquid with a pleasant aromatic odor. Insoluble in water and sinks in water. Flash point near 120°F. Vapors are heavier than air. Used as a solvent for oils and fuels. | [Air & Water Reactions]
Flammable. Insoluble in water. | [Reactivity Profile]
Simple aromatic halogenated organic compounds, such as dibromobenzene , are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. | [Health Hazard]
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | [Fire Hazard]
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | [Potential Exposure]
Dibromobenzene is used as a solvent
for oils and in organic synthesis. | [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, includ-
ing 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 medi-
cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Personal Protective Methods: Wear protective eye protec-
tion, gloves, and clothing to prevent any reasonable proba-
bility of skin or eye contact. Safety equipment suppliers/
manufacturers can provide recommendations on the most
protective glove/clothing material for your operation. All
protective clothing (suits, gloves, footwear, and headgear)
should be clean, available each day, and put on before
work. Contact lenses should not be worn when working
with this chemical. Wear splash-proof chemical goggles
and face shield when working with liquid full facepiece
respiratory protection is worn. Employees should wash
immediately with soap when skin is wet or contaminated.
Provide emergency showers and eyewash. | [Shipping]
UN1993 Flammable liquids, n.o.s., Hazard
Class: 3; Labels: 3-Flammable liquid, Technical Name
Required. UN2514 Bromobenzene, Hazard Class: 3;
Labels: 3-Flammable liquid. | [Incompatibilities]
Extremely flammable. May form
explosive mixture with air. Incompatible with 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, and epoxides. | [Description]

ChEBI: 1,2-dibromobenzene is a dibromobenzene. | [storage]
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with dibromobenzene you should betrained on its proper handling and storage. Store in tightlyclosed containers in a cool, well-ventilated area away fromstrong oxidizers. Sources of ignition, such as smoking andopen flames, are prohibited where dibromobenzene is used,handled, or stored, in a manner that could create a potentialfire or explosion hazard. |
