                          III.  HEALTH HAZARD INFORMATION

      OSHA STANDARD:  NA

      NIOSH RECOMMENDED LIMIT:  NA

      ACGIH RECOMMENDED LIMIT:  NA

      TOXICOLOGY

           A.  ACUTE TOXICITY

               ORAL:  LD50 = >5000 mg/kg (rat) (56)

           B.  SUBACUTE AND CHRONIC TOXICITY:

           In 2-yr feeding trials rats receiving 1000 mg/kg diet suffered no
      ill-effect (26).


                        IV.  ENVIRONMENTAL  CONSIDERATIONS

           Moderate hazard to birds, fish and beneficial insects.
      Phytotoxicity has occurred when mixed with certain organophosphorous
      insecticides (48).
           It is rapidly metabolized in rats and is excreted in the urine as
      the sulphate conjugate of 3,5-dichloro-4-aminophenol.  In plants it is
      metabolized to polar compounds (26).


                      V.  EMERGENCY AND FIRST AID PROCEDURES

           The chemical information provided below has been condensed
      from original source documents, primarily from "Recognition and

                                VII.  COMPATIBILITY

           Incompatible with miscible oil formulations of organic phosphate
      insecticides (48).


                            VIII.  PROTECTIVE MEASURES

      STORAGE AND HANDLING:  Keep out of the reach of children.  Harmful if
