risk. Prevent fire extinguishing water from contaminating surface water or the ground water system.
Specific methods: Use standard firefighting procedures and consider the hazards of other involved
materials.
General Fire hazards: Not combustible
Hazardous Combustion Products: Carbon oxides. Hydrogen chloride. Other irritating fumes and smoke.

equipment, refer to Section 8 of the SDS.
Methods and Materials for Containment and Cleaning Up: Large Spills: Ventilate the area. Stop leak if it
can be done without risk. Use water spray to reduce vaports or divert vapor cloud drift. Dike the spilled
material where this is possible. Stop leak if it can be done without risk. Absorb spillage to prevent material
damage. Absorb in vermiculite, dry sand or earth, and place into containers. Prevent entry into waterways,
sewer, basements, or confined areas.
Folliowing product recovery, flush area with water.
Small Spills: Absorb spillage with noncombustible, absorbent material. Clean surface thoroughly to remove
residual contamination.
