SECTION : FIRE AND EXPLOSItflN` D TA WER EPER Flash Point and Method I Autoignition Temperature Flammability Limits in Air 127(-11.1'C)CC L 928-F(498-C) 5b by Volume 1.3% 7.15'0 Extinbuishing Media: Use dry chemical,foam,or carbon dioxide to put out benzene fires.Water may be ineffective as an extinguishing agent because it can scatter and spread the fire.Use water to cool fire-exposed containers,flush spilis away from exposures,disperse benzene vapor,and protect personnel attempting to stop an unignited benzene leak. Unusual 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 room temperature;always use this material in a way that minimizes dispersion of its vapor into general work areas. Special Fire-fighting Procedures: Wear a self-contained breathing apparatus(SCBA) with a full facepiece operated in the pressure- demand or positive-pressure mode. SECTION 5, REACTIVITY 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 64: bromine pentafluoride,chlorine,chlorine trifluoride, chromic anhydride,nitryl perchlorate,oxygen,ozone,perchlorates, perchloryl fluoride and aluminum chloride,permanganates and sulfuric acid,potassium peroxide,silver perchlorate,and sodium peroxide. Conditions to Ati•oid: Avoid all exposure to sources of ignition and to incompatible chemicals. Hazardous Products of Decomposition: Toxic gases like carbon monoxide(CO)may be produced during benzene fires.
