<br /> Flash Point;Noncombustible Autoignition Temperature: None reported LEL:None reported* UEL•None reported*
<br /> Extinguishing Media: Use extinguishing agents suitable for surrounding fire.
<br /> Unusual Fire or Explosion Hazards *Extreme heat or contact with many metals liberates hydrogen gas which has explosion limits of 4 to 750
<br /> Special Fire-fighting Procedures:Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus
<br /> (SOBA)with a full faceptece operated in pressure.-demand or positive-pressure mode Structural firefighter's protective clothing is ineffective for
<br /> fires involving hydrochloric acid.Stay away from ends of tanks Cool tanks with water spray until well after fire is out.Do not release runoff
<br /> from fire control methods to sewers or waterways

<br /> Stability/Polymerization:HydrochIonc acid has high thermal stability(decomposes a13239 6'F/1782'C) Hazardous polymerization does not
<br /> occur unless exposed to aldehydes or epoxides
<br /> Chemical Incompatibllitles:Polymenzes on contact with aldehydes or epoxides,attacks most metals(except mercury,silver,gold platinum,
<br /> tantalum,acid some alloys).some plastics,rubber,and coatings,reacts explosively with alcohols+hydrogen cyanide.potassium permanganate,

<br /> Carcinogenicity:The L4RC, NTP, and OSHA do not list HCl as a carcinogen
<br /> Summary of Risks HCl is a highly corrosive liquid and depending on concentration and duration of exposure,symptoms range from irritation
<br /> to Ulcerations and permanent injury Target Organs:Eyes,skin,respiratory tract,and liver(in animals) Primary Entry Routes:Inhala-
