<br /> r1rigulshlng Medla.For small fires,use dry chemical,carbon dioxide(CO2),water spier or regular foam For large fires,use water spray fog or
<br /> regular foam.Water may be ineffective.Use water spray to cool file-exposed containers Unusual Fire or Explosion Hazards Xylene vapors or
<br />' liquid(which floats on watts)may travel to an ignition source and flash back.The heat of fire may cause conta3rim to explode and/or produce
<br /> irritating or poisonous decomposition products Xylene may present a vapor explosion hazard indoors,outdoors,or in sewers Accumulated static
<br /> electricity may occur from vapor or liquid flow sufficient to cause ignition Special Fire-fighting Procedures:Because fire may produce toxic
<br /> thermal decomposition products wear a self-contaaned breathing apparatus(SCBA)with a full facepiece operated in pressure-demand or positive
<br /> pressure mode Structural firefighter's protective clothing will provide limited protection If feasible and without risk move containers from fire area
<br /> Otherwise,cool fire-exposed containers until well after fire is extinguished Stay clear of tank ends Use unmanned hose holder or monitor nozzles for
<br /> massive cargo foes If impossible,withdraw from area and let fire bum Withdraw immediately in case of any tank discoloration or rising sound from
<br /> venung safety device Do not release runoff from fire control methods to sewers or waterways
<br />' Section S. Reactivity Data
<br /> StabilitylPolymerirataon Xylene is stable m room temperature un closed containers under normal storage and handling conditions Hazardous
<br /> polymerization cannot occur Xylene is easily chlorinated,sulfonated or nitrated Chemical Incom pat lbll flies Incompatibilities include strong
<br />' acids and oxidizers and 1,3-dnchloro 5,5-dimethyl 2,4-irrudazolidnndione(dichlorohydruntorn) Xylene attacks some forms of plastics,rubber and
<br /> coatings Conditions to Avoid Avoid heat and igruuon sources and incompatibles Hazardous Products of Decomposition Thermal oxidative
<br /> decomposition of xylene can produce carbon dioxide,carbon monoxide,and vinous hydrocarbon products
<br /> Section 6. Health Hazard Data
<br /> Carcinogenicity The LkRC,tna`I NTP,(t6;)and OSHA(16")do not list xylene as a carcinogen Summary of Racks Xylene is an eye mucous
<br /> membrane and respiratory tract irrn=L irritation stare at 200 ppm,severe breathing dill iculues which may be delayed in onset can occur at high
<br /> concentrations It is a central nervous system(CNS)depressant and at high concentrations can cause coma Kidney and liver damage can occur with
<br /> xylene exposure With prolonged or repcaLed cutaneous exposure,xylene produces a defatung dernriatitis Chrome toxicity is not well defined but it
<br /> is less toxic than benzene Prior to the 1950s benzene was often found as a contaminant of xylene and the effects attributed to xylene such as blood
<br /> dyscrasias are questionable Since the late 1950s.xylenes have been visually benzene-free and blood dyscrasias have not been associated with
<br /> xylenes Chronic exposure to lugh concentratiom of xylene in anima]studies have demonstrated rrulk reversible decrease in red and white cell
<br /> counts as well as increases in platelet counts Conrintu on next pag
