<br /> SECTION 3. PHYSICAL DATA
<br /> Boiling Point 176'F(80°C) Water Solubility (%) Slight
<br /> -- Melting Point 42`F(55'C) % Volatile by Volume 100
<br /> Vapor Pressure 75 Tom at 68°F(20°C) Molecular Weight 78 Grams/Mole
<br /> Vapor Density (Air = 1) >1 Specific Gravltv (H=O = 1) 0 87865 at 68'F(20 C)
<br /> Appearance and Odor A colorless liquid,characteristic aromatic odor
<br /> SECTION 4 FIRE AND EXPLOSION DATA L NVER I UPPER
<br /> Flash Point and Method Autoignition Temperature Flammability Limits in Air
<br /> 12 F(-11 1`C)CC 92'Z'F(498'0 %by Volume 13% 7 1%
<br /> Lxtinguishinb Media Use dry chemical,foam,or carbon dioxide to pu,out bencene fires Water may be meffectne as an extinguishing
<br /> agent because it can Ncatter and spread the fire Use%katcr to cool fire-cxposed containers,flush spills arkay from exposures,disperse benzene
<br /> vapor, and protect personnel attempting to stop an unignited benzene leak
<br /> Unusual Fire or Explosion Hazards Benzene vapor is heavier than air and can collect in low-lying areas such as sumps or wells
<br /> Eliminate all sources of ignition there to prevent a dangerous flashback 10 the original liquid benzene Danger Explosive and flammable
<br /> benzene vapor-air rruxtures can easily form at room temperature,always use this material in a way that minimizes dispersion of its vapor into
<br /> general work areas
<br /> Special Fire-fighting Procedures Wear a self-contained breathing apparatus(SCBA)with a full facepiece operated in the pressure-
<br /> demand or positive-pressure mode
<br /> SECTION 5 REACTIVITY DATA
<br /> Benzene is stable in closed containers during routine operations It does not undergo hazardous polymerization
<br /> Chemical Incompatibilities Hazardous chemical reactions involving benzene and the following materials are reported in Genium
<br /> reference 84 bromine pentafluonde,chlorine,chlorine trifiuonde,chromic anhydride,nitryl perchlorate, oxygen,ozone,perchlorates,
<br /> perchioryi fluoride and alurrunum chloride,permanganates and sulfune acid,potassium peroxide,silver perchlorate, and sodium peroxide
<br /> Conditions to AN aid Avoid all exposure to sources of ignition and to incompaitble chemicals
<br /> Hd7ardous Products of Decomposition Toxic gases like carbon monoxide(CO)may be produced during benzene fires
