<br /> Extinguishing Media: For small fares,use dry chemical,carbon di6xide(CO2),water spray,or alcohol-resistant foam.For large fires,use water
<br /> spray,fog,of alcohol-resistant foam.Do not scatter material with any more water than needed to extinguish fire.
<br /> Unusual Fire or Explosion Haurds:Methyl alcohol is a dangerous fire hazard when exposed to heat,flame,or oxidizers.It is explosive in its
<br /> vapor form when exposed to heat or flame,Vapors may travel to an ignition source and flash back.
<br /> Special Fire-righting Procedures:Since fire may produce toxic thermal decomposition products,wear a self-contained breathing apparatus
<br /> (SOBA)with a full facepitce operated in pressure-demand or positive-presstrre mode.Also,wear full protective clothing.Structural firefighters'
<br /> protective clothing is ineffevivc for fires involving methyl alcohol.it possible without risk,remove container from fire area.Apply cooling water
<br /> to sides of fue-exposed container until fire is well out Stay away from ends of tanks.Leave area immediately if you h=a rising sound from
<br /> venting safety device or see any tart,discoloration due to fire.Be aware of runoff from fire control methods.Do not release to Sewers Or Water-
<br /> ways.

<br /> Stabilily/Polyrneriz2flon:McLhyl alcohol is stable ai room temperature in closed containers under normal storage and handling conditions.
<br /> Hazardous polymerization cannot occur.
<br /> Chemical Incompatibliftles: Methyl alcohol is incompatible with beryllium dihyd.ride,metals(such as potassium or magnesium),oxidants(such
<br /> as barium perchloratc,bromine,chlorine,hydrogen peroxide, and sodium hypochlorite),potassium Lenbutoxicic,carbon tetrachloride+metals;

<br /> hydroxide,cyanuric chioride, and nirric acid.
<br /> Conditions to Avoid: Avoid vapor inhalation and contact with oxidizers and other incompatibles.
<br /> Hazardous Products of Decomposition:Thermal oxidative,decomposition of methyl alcohol can produce carbon oxides(CO and CO,).possible
<br /> formaldehyde(HCHO)and acrid smoke,and irritating fumes.
