<br /> Extinguishing Media:Use dry chemical,foam,or carbon dioxide to extinguish benzene fires Water may be ineffective as an extinguishing
<br /> agent since it can scatter and spread the fie Use water slay to cool Fie-exposed containers,flush spills away from exposures,disperse benzene
<br /> vapor,andpprrotect l attempting to stop an unignited benzene leak
<br /> Unusual Flre or lesion Hazards-Benzene is a Class 1B flammable liquid.A concentration exceeding 3250 ppm is considered a potential
<br /> fie explosion Benzene vapor is heavier than air and can collect in low Iyu►g areas or travel to an ignition source and flash back Explosive
<br /> and flammable benzene vapor-air riuxuires can easily form at room temperature Eliminate all igmtxon sources where benzene is used,handled,or
<br /> stored
<br /> Special Fire-fighting Procedures:Isolate hazard area and deny entry Since fie may produce toxic fumes,wear a self-contained breathing
<br /> gpparaitds(SOBA)with a full facepiece operatedin the pressure-demand or positive-pressure mode and full protective equipmenL Structural
<br /> firefighter's protective clothing provideslimited protection.Stay out of low areas Be aware of runoff from fire control methods Do not release to
<br /> sewers or waterways Runoff to sewer can create pollution,fire,and explosion hazard.

<br /> StabilitylPolymerization:Benzene is stable at room temperature in closed containers tinder normal storage and handling conditions Hazardous
<br /> polymerization cannot occur.
<br /> Chemical Incompatibiilties:Benzene explodes on contact with dibmane,permanganic acid,bromine pentafluonde,peroxoddsulfunc acid,and
<br /> peroxomonosulfuric acid It ignites on contact with dtoxygen difluonde,dioxygenyl tetrafluoroborate,iodine heptafluoride,and sodium peroxide

<br /> acid and arsenic pentafluonde+potassium methoxide(explodes above 30'C) A vigorous or incandescent reaction occurs with bromine
<br /> trifluonde,uranium hexailuoride,and hydrogen+Raney nickel[above 410'F(210'C)] Benzene is incompatible with oxidtzmg materials
<br /> Condidons.to Avoid:Avoid heat and ignition sources
<br /> Hazardous Products of Decomposition:Thermal oxidative decomposition of benzene can produce toxic gases and vapors such as carbon
<br /> monoxide
