SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Mix erbon with a flammable solvent then spray the soln into an incinerator equipped with afterburner and scrubber. Recommendable method: Incineration.

FASTING RATS BECAME DISTINCTLY POIKILOTHERMIC FOR PERIOD AS LONG AS 7 HR AFTER SC INJECTION (200-300 MG/KG)... IN A COLD ENVIRONMENT THE METABOLIC RATE ROSE ONLY SLIGHTLY & DEEP BODY TEMP FELL. ...HYPERMETABOLISM & HYPERTHERMIA...OCCURRED WHEN INJECTED RATS WERE KEPT IN A WARM ROOM (35 °C); APPARENTLY THE DEATH OF THESE ANIMALS WAS DUE TO HYPERPYREXIA. /2,4,5-T/

WHEN APPLIED TO SKIN OF RATS DAILY FOR 3 WK IN 1-3% SOLN, ERBON DID NOT IRRITATE SKIN OR APPARENTLY AFFECT BODY WT OR PERIPHERAL BLOOD COMPOSITION.

THE TLM (LC50) VALUES OF 33 PESTICIDES FOR CYPRINUS CARPIO, ORYZIAS LATIPES, MISGURNUS ANGUILLICAUDATUS, DAPHNIA PULEX, D CARINATA, MOINA MACROCOPA, INDOPLANORBIS EXUSTUS & CIPANGOPALUDINA MALLEATA ARE GIVEN.

1. BATHE & SHAMPOO WITH SOAP & WATER TO REMOVE CHEMICALS FROM SKIN & HAIR. INDIVIDUALS WITH CHRONIC SKIN DISEASE OR KNOWN SENSITIVITY TO CHEMICALS SHOULD EITHER AVOID USING HERBICIDES OR TAKE EXTRAORDINARY MEASURES TO AVOID CONTACT. 2. FLUSH...CHEMICALS FROM EYES WITH COPIOUS AMOUNTS OF CLEAN WATER FOR 10-15 MINUTES. 3. IF SYMPTOMS OF ILLNESS OCCUR DURING OR FOLLOWING INHALATION OF SPRAY, REMOVE VICTIM FROM CONTACT...FOR AT LEAST 2 DAYS. ALLOW SUBSEQUENT CONTACT WITH CHLOROPHENOXY COMPOUNDS ONLY IF EFFECTIVE RESPIRATORY PROTECTION IS PRACTICED. /CHLOROPHENOXY COMPOUNDS/

4. IF...INGESTED, SPONTANEOUS EMESIS USUALLY OCCURS. ORDINARILY, THIS EMPTIES THE STOMACH AS EFFECTIVELY AS INTUBATION & LAVAGE. IF VIGOROUS EMESIS HAS NOT OCCURRED & IF VICTIM IS FULLY ALERT, INDUCE EMESIS WITH SYRUP OF IPECAC (ADULTS 12 YEARS & OLDER, 30 ML; CHILDREN UNDER 12 YEARS, 15 ML), FOLLOWED BY 1-2 GLASSES OF WATER. FOLLOWING EMESIS, ADMIN....ACTIVATED CHARCOAL /PRC- 30 G ACTIVATED CHARCOAL IN 3-4 OZ OF WATER (CHILDREN), 100 G IN 8-10 OZ OF WATER (ADULTS)/...TO LIMIT ABSORPTION OF HERBICIDE REMAINING IN GUT. /CHLOROPHENOXY COMPOUNDS/

5. IF CONSCIOUSNESS LEVEL IS DEPRESSED...EVACUATE STOMACH BY INTUBATION, ASPIRATION, & LAVAGE /PRC- WATER IN CHILDREN & ISOTONIC SALINE IN ADULTS/. BECAUSE PETROLEUM DISTILLATES ARE COMMONLY INCLUDED IN CHLOROPHENOXY FORMULATIONS, GASTRIC INTUBATION INCURS A RISK OF HYDROCARBON PNEUMONITIS FROM ASPIRATION. FOR THIS REASON: A. IF VICTIM IS UNCONSCIOUS OR OBTUNDED & FACILITIES ARE AT HAND, INSERT ENDOTRACHEAL TUBE (CUFFED, IF AVAILABLE) PRIOR TO GASTRIC INTUBATION. B. KEEP VICTIM'S HEAD BELOW LEVEL OF STOMACH DURING INTUBATION & LAVAGE (TRENDELENBURG, OR LEFT LATERAL DECUBITUS, WITH HEAD OF TABLE TIPPED DOWNWARD). KEEP VICTIM'S HEAD TURNED TO LEFT. C. ASPIRATE PHARYNX AS REGULARLY AS POSSIBLE TO REMOVE GAGGED OR VOMITED STOMACH CONTENTS. /CHLOROPHENOXY COMPOUNDS/

5. AFTER ASPIRATION OF GASTRIC CONTENTS & WASHING OF STOMACH, INSTILL...ACTIVATED CHARCOAL.../PRC- 30 G ACTIVATED CHARCOAL IN 3-4 OZ OF WATER (CHILDREN), 100 G IN 8-10 OZ OF WATER (ADULTS)/ TO LIMIT ABSORPTION OF REMAINING TOXICANT. DO NOT INSTILL MILK, CREAM, OR OTHER MATERIALS CONTAINING VEGETABLE OR ANIMAL FATS, AS THESE ARE LIKELY TO ENHANCE ABSORPTION. 6. IF BOWEL MOVEMENT HAS NOT OCCURRED IN 4 HOURS & PATIENT IS FULLY CONSCIOUS, GIVE SODIUM SULFATE, 0.25 G/KG, AS CATHARTIC. MAGNESIUM SULFATE & CITRATE, IN COMPARABLE DOSAGES, ARE EQUALLY SUITABLE IF RENAL FUNCTION IS ADEQUATE. RETAINED MAGNESIUM MAY DEPRESS CNS FUNCTION. /CHLOROPHENOXY COMPOUNDS/

7. IN SEVERE POISONINGS BY VERY LARGE AMOUNTS OF INGESTED CHLOROPHENOXY ACIDS, FORCED ALKALINE DIURESIS MAY SAVE VICTIM'S LIFE. ASSESS SERUM ELECTROLYTE CONCENTRATIONS, & SERUM & URINE PH. IF METABOLIC ACIDOSIS IS PRESENT, INFUSE SOLUTIONS OF SODIUM BICARBONATE AT RATES SUFFICIENT TO KEEP THE URINE DISTINCTLY ALKALINE, CONTINUING UNTIL PLASMA CONCENTRATIONS OF CHLOROPHENOXY COMPOUNDS ARE LESS THAN ABOUT 10 UG/ML. /CHLOROPHENOXY COMPOUNDS/

MEDICATION

...INTRODUCED, IN 1955, BY THE DOW CHEMICAL CO UNDER TRADE MARKS OF "BARON" &, IN GREAT BRITAIN, "ERBON", UNDER PROTECTION OF USP 2,754,324. MADE BY THE ESTERIFICATION OF DALAPON WITH 2-(2,4,5-TRICHLOROPHENOXY)ETHANOL...

EBRON PRODUCT DISCONTINUED BY THE DOW CHEMICAL CO.

FORMULATION IS COMPATIBLE WITH HARD WATER & MOST HERBICIDES.

ERBON HAS A BROAD SPECTRUM OF ACTIVITY BECAUSE THE 2,4,5-TRICHLOROPHENOXYETHANOL FRAGMENT IS TOXIC TO BROAD-LEAVED PLANTS & THE 2,2-DICHLOROPROPIONIC ACID FRAGMENT IS SPECIFICALLY TOXIC TO GRASSES.
