' .SECTION 4.TIRE AND EXPLOSION' DATA'..:-` W R UPPER Flash Point and Method Autoignition Temperature Flammability Limits in Air + 12'37(-11.VC)CC 92S'F(49S'C) 90 by Volume 1.3% 7.190 Extinguishing Media: Use dry chemical,foam,or carbon dioxide to put out benzene finis.Water may be ineffective as'an extinguishing agent because it can scatter and spread the frre.Use water to cool fits-exposed containers,flush spills away from exposures,disperse benzene vapor,and protect personnel attempting to stop an unignited.benzene leak. Un usual Fire or Explosion Hazards: Benzene vapor is heavier than air and can collect in low-lying areas such as sumps or wells. Eliminate all sources of ignition there to prevent a dangerous flashback to the original liquid benzene.Danger:Explosive and flammable benzene vapor-air mixtures can easily form at Mom temperature;always use this material in a way that minimizes dispersion of its vapor into general work areas. Special Fire-fighting Procedures: Wtar a self-contained breathing apparatus(SCEA)with a full facepiece operated in the pressure- demand or positive-pressure mode. SECTION' S. REACTIN'ITY DATA Benzene is stable in closed containers during routine operations. It does not undergo hazardOUS polymerization. Chemical Incompatibilities: Hazardous chemical reactions involving benzene and the following materials are reported in Genium reference 84: bromine pcniafluoride,chlorine,chlorine trifiuoride,chromic anhvdride,nitrvl perchloratc,oxygen,ozone,perchlorates, perchloryl fluoride and aluminum chloride,permanganates and sulfuric acid,potassium peroxide,silver perchlorate,and sodium peroxide. Conditions to Avoid: Avoid all exposure to sources of ignition and to incompatible chcrnicais. Hazardous Products or Decomposition: Toxic gases like carbon monoxide(CO)may be produced during benzene fires.
