' Special Fire-fighting Procedures Wear a self-contained breathing apparatus(SOBA)with a full facepiece operated in the pinssure- demand or positive-pressure mode ' SECTION 5. REACTIVITY DATA Xylene is stable in closed containers during murine operations It does not undergo hazardous polymerization ' Chemical Incompatibilities This matenal may react dangerously with strong oxidizers Conditions to Avoid: Avoid any exposure to sources of ignition and to strong oxidizers Hazardous Products of Decomposition: Carbon monoxide(CO)may be evolved during xylene fires. eoprnw a 19"0=22 rohmms CapQmoa
