Flammabilit Limits In Air <br /> 1200 -llC TCC 1044oF 562oC Volume I 1.3 7.1 <br />- Extinguishing Media: Water fog. CO2, dry chemical or foam, Use a blanketing effect to <br /> smother fire. A water stream will scatter the fire. A water spray can be used to cool <br /> fire exposed containers. <br /> Firefighters should wear approve] self-contained hreathing apparatus. <br /> This material can form explosive and flammable mixtures with r.Sr at room tempersture. It <br /> is a severe ex losion hazard and toxic hazard in a fire situation. Vcpore can flow <br /> along surfaces to flash back. <br /> SECTION V, REACTIVITY DATA <br /> Benzene is as stable compound under normal storage and use conditions; it does not polymer. <br /> ize. <br /> Benzene will react vigorously with strong oxidizers such as ozone, permanganate, sulfuric <br /> ar nitric aci�!s, potassium peroxide, sodium peruxide, et al. It is a flammable liquid. <br /> OSHA Class IB. Heating greatly increases the fire and axplosinn hazards. <br /> Oxidation in air will produce oxides of carbon and nitrogen. <br /> .
