4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

4.2 Most important symptoms/effects, acute and delayed

This material is extremely toxic; probable oral lethal dose in humans is 5-50 mg/kg, or between 7 drops and 1 teaspoonful for a 150-lb. person. Many medical conditions will be aggravated by this material. (EPA, 1998)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Administration of vitamin K1, SC, to anticoagulant-poisoned (diphenadione) dogs provided diagnostic information within 4 hours, when vitamin K1 and its epoxide were measured in canine sera. Twelve dogs (2 groups of 6) were given 2.5 mg of diphenadione/kg of body weight for 3 days. Dogs were treated with vitamin K1, 2.5 (n = 6) or 5 mg/kg/day (n = 6) SC for 21 days, and their responses were compared. Four nonexposed control dogs were given 5 mg of vitamin K1/kg/day. Serum concentration of vitamin K epoxide was significantly (P less than 0.02) higher in diphenadione-exposed dogs than in control dogs 1 to 4 hours after the initial vitamin K1 treatment on day 4. Vitamin K epoxide/vitamin K1 ratios were similarly higher and became more distinct. Cessation of vitamin K1 therapy on day 24 resulted in prolongation of one-stage prothrombin times in diphenadione-exposed dogs, becoming clearly evident on day 27. Serum vitamin K1 concentrations were not detectable on day 27 in diphenadione-exposed dogs, whereas serum vitamin K1 concentrations were readily detectable in control dogs. One-stage prothrombin time changes, during days 24 to 32, indicated 5 mg of vitamin K1/kg provided better protection than did 2.5 mg of vitamin K1/kg. Coagulopathy in the dogs was resolved by day 32.

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Sensitive to light

10.3 Possibility of hazardous reactions

Not flammable or combustible.DIPHACINONE is a ketone, and behaves as a weak acid. Forms water soluble alkali metal salts. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

12.2 Persistence and degradability

AEROBIC: Radio-labeled (benzyl ring or both phenyl rings)[14C]diphacinone was metabolized with a half-life of 28.3 to 31.7 days, respectively, in sandy loam soils incubated aerobically in the dark at 25°C for 3.5 months. The major degradate (defined as >10% of the applied) detected in the phenyl ring labeled study was identified as diphenylglycolic acid and was present at a maximum of 24.5% of the applied at one month after application. Diphenylglycolic acid was also detected in the benzyl ring labeled study at a very low concentration (<10% of the applied). By 3.5 months post-treatment, 42.5% of the applied radioactivity was accounted for as 14CO2 in benzyl ring labeled [14C]diphacinone, and 37.3% of the applied radioactivity was accounted for as 14CO2 in the phenyl ring labeled [14C]diphacinone(1).

12.3 Bioaccumulative potential

An estimated BCF of 79 was calculated in fish for diphacinone(SRC), using a log Kow of 4.27(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

Kd values of 5.4-1000 have been measured for diphacinone(1). The compound was immobile in columns (60 cm in length) packed with sandy loam, silt loam, sand, and loamy sand soils to a depth of 30 cm. Diphacinone was detected in the 0-6 cm layer in the columns with sandy loam and silt loam soils. In the sand soil, diphacinone was detected in the 0-6 cm layer (at 117.1% of the applied) and in the 6-12 cm layer (at <3% of the applied). Diphacinone was present in the 0-6 cm layer of the loamy sand soil at 76.1% of the applied, and was also present in the 6-12 cm, 12-18 cm, and 18-24 cm layers at 3.4%, 4.8%, and 4.4% of the applied, respectively. Diphacinone was not detected in any of the leachates collected from the four soil columns(2).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
