         medical attention.





SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE



         SPILL OR LEAK PROCEDURES: Do not flush into sewers. Place spilled

         solution into containers for proper disposal. Absorb liquid into sand or

         clay and remove solid residue. If necessary, contact local police, fire

         department, National Response Center and/or CHEMTREC.



         WASTE DISPOSAL METHOD: Apply to ground as fertilizer. Avoid contamination

         of surface water or groundwater. Contact state, federal or local

         environmental regulatory agencies for proper disposal procedures and

         locations.



         HANDLING AND STORAGE PRECAUTIONS: Store in tanks in a well-ventilated

         building or out-of-doors. Avoid storage with combustible materials. Wear

         goggles/face shield, rubber gloves and protective clothing when moving

         product or when the possibility of splashing exists.



         OTHER PRECAUTIONS: Do not store in unlabeled or recycled containers

         without adequate precautions.









SECTION VIII - CONTROL MEASURES



         RESPIRATORY PROTECTION (SPECIFY TYPE): Generally, none needed. If free

         ammonia is present, ammonia cartridge respirators are indicated.



         VENTILATION:

         LOCAL EXHAUST: In confined areas if free ammonia is present.

         MECHANICAL: Satisfactory      SPECIAL: N/A             OTHER:       N/A



         PROTECTIVE GLOVES:    Non-absorbent rubber or equivalent.



         EYE PROTECTION:    Goggles, face shield



         OTHER PROTECTIVE CLOTHING/EQUIPMENT: Long sleeved shirts are recommended.



         WORK/HYGENIC PRACTICES:     Wash hands thoroughly after handling.   Do not let

         DEPARTMENT OF TRANSPORTATION REQUIREMENTS:   None





SECTION X - SPECIAL PRECAUTIONS (OPTIONAL)



         Concentrated or dried UAN solutions can detonate under conditions of severe

         heat, fire or shock. The dried mixture is combustible and will increase

         the severity of a fire if mixed into combustible materials such as wood,

         straw, coal or flammable liquids.
