<br /> Extingulshing Media: Use dry chemical,foam,or carbon dioxide to put out benzene Gres.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 spills away from exposures,disperse benzene
<br /> vapor,and protect personnel attempting to stop as unignited benzene leak.
<br /> Unusual Fire or Exploslon Hazards: Benzene v4por 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 origtnai liquid benzene.Danger:Explosive and flammable
<br /> benzene vapor-air mixtures can easily form at room temperature:always use this material in a way that m;nimizes dispersion of its vapor into
<br /> general word:areas.
<br /> Special Fire-flghting Procedures: Fear a self contained breathing apparatus(SOBA)with a full facepicce operated in the pressure.
<br /> demand or positive-pressure mode.
<br /> SECTION ;. 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 pcmafluoride,chlorine,chlorine trifluoride,chromic anhydride,nitryl perchlorate, -Ygcti,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 c r rrdcals.
<br /> Hazardous Products of Decomposition: Toxic gases like carbon rLonoxide(CO)maybe produced during benzene fires.
