<br /> and its flame speed-37 rni/sac Vapor poses an explosion hazard indoors,outdoors,and in sewers May accumulate static S ion Sped )
<br /> Fire-fighting Procedures-Because fire may produce toxic thermal dreornposition products,wear a self-contained brenilun
<br /> with a full facepiece opes•ated in pressure-derrua or positive-pressure mode-Structural firefightei?s protective eiothutg provides only limited
<br /> ' protection Apply cooling water to sides of tanks until well after fire is out.Stay away from ends of tanks.For massive fire in cargo any use
<br /> morutor nozzles or unmanned hose holders,if impossible,withdraw from fire and let burn.Withdraw unmediaWy if you hear a ns ung around from
<br /> venting safety device or notice any tank discoloration due to fire because a BLEVE(boiling liquid expanding vapor expkmou)may be uruninrnL
<br /> Do not release runoff from fire control methods to sewers or waterways

<br /> nose,and respumtory tract-Inhalation of fugh concentrations produces a narcotic effect sometimes leading to coma as well as liver and kidney
<br /> damage.93%of inhaled toluene is retained in the body of which 8096 is metabolized to beruose and,then to Fuppuric acid and excreted in unrw-
<br /> The remainder is metabolized to o—cresol and excreted or exhaled unchanged-Toluene metabolism is tnlu'bntcd by alcohol ingestion and is synergis
