<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 Torrs at 68'F(20*C) Molecular Weight. 78 Grams/Mole
<br /> Vapor Density (Air = 1) >1 Specific Gravity (H2O = 1) 087865 at687(20'C)
<br /> Appearance and Odor A colorless liquid,characteristic aromatic odor
<br /> SECTION 4 FIRE AND EXPLOSION DATA LOWER UPPER
<br /> Flash Point and Method Autoignition Temperature Flammability Limits in Atr

<br /> Extinguishing Media Use dry chemical,foam,or carbon dioxide to put out benzene fires Water may be ineffective as an extinguishing
<br /> agent because It can scatter and spread the fire Use water to cool fire-exposed containers,flush spilis away 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 to the original liquid benzene Danger Explosive and flammable
<br /> benzene vapor-air mixtures can easily form at room temperature,always use this matenal 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(SOBA)with a full facepiece operated in the pressure-
<br /> demand or posiw,c-pressure mode
<br /> SECTION 5 REACTIVITY DATA
<br /> Benzene is stable inclosed containers during routine operations Itdocs not undergo hazardous polymerization
<br /> Chemical Incompatibilities Hazardous chemical reactions involing benzene and the following materials are reported in Genium
<br /> reference 84 brorrune pcntafluonde,chlorine,chlorine trifluonde,chromic anhydride,nitryl perchlorate,oxygen,ozone,perchlorates,
<br /> perchloryl fluoride and aluminum chloride,permanganates and sulfuric acid,potassium peroxide,silver perchlorate,and sodium peroxide
<br /> Conditions to Avoid Avoid all exposure to sources of ignition and to incompatible chemicals
<br /> Hazardous Products of Decomposition Toxic gases like carbon monoxide(CO)may be produced during benzene fires
