Thermal decomposition in the presence of oxidizing materials produces toxic chlorine fumes and
explosive hydrogen gas.
Hazardous Polymerization: Will not occur.
Incompatibilities: Highly reactive with strong bases, metals, metal oxides, hydroxides, amines,
carbonates and alkaline materials. Incompatible with cyanide, sulfides, sulfites and formaldehyde.
11. Toxicological Information
Lethal inhaled concentration (LC50) in rats: 3,124 ppm/1 hr
Not listed on the OSHA, NTP or IARC list of carcinogens.
12. Ecological Information
Environmental Fate: Rapidly hydrolyzes when exposed to water. Exhibits extensive evaporation
from soil surfaces. Transport through soil may contaminate ground water and will dissolve some
of the soil materials (especially those with carbonate bases). Acid will be neutralized to a large
degree by contact with carbonates in soil.
Environmental Toxicity: Lethal to fish from 25 mg/l and up. Toxic to aquatic organisms as a
result of pH shift.
13. Disposal Considerations
Whatever cannot be recovered or recycled should be handled as Characteristic Hazardous
Waste (pH <2.0) and sent to a RCRA approved waste facility. State and local disposal regulations
may differ from federal regulations. Dispose of container and contents in accordance with federal,
state and local laws.
