Molecular Weight; 78 Grams/Mole Vapor Density (Air = 1): >1 Specific Gravity (H2O = 1): 0.57865 at68'F(20'C) Appearance and Odor: A colorless liquid;characteristic aromatic Odor. i SECTION 4. FIRE AND EXPLOSION DATA LOW R UPPER Flash Point and Method Autoignition Temperature. Flammability Limits in Air 127 f-1 1.1'C)CC 928'F f499'Cl %by Volume 1.3% 7.19c Extinguishing, 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 spills away from exposures,disperse benzene vapor,and protect personnel attempting to stop an unignited benzene leak. 1 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 away that minimizes dispersion of its vapor into E peneral work areas. Special Fire-fighting, Procedures: Wear a self-contained breathing apparatus(SOBA)with a full facepiece operated in the pressure- demand or positive-pressure mode. SECTION S. 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 84: bromine pentafluoridc,chlonne,chlorine trifiuoride,chromic anhydride,nitryl perchlorate,oxygen,ozone,perehlorates, } perchioryl fluoride and aluminum chloride,permanganates and sulfuric acid,potassium peroxide,silver perchlorate,and sodium peroxide. I r II } Conditions to Avoid: 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. rt C rynghl C.19SE Gtm.m F'ubli%hmr cwgx Oon. .
