4.First-aid measures

4.1 Description of necessary first-aid measures

General advice

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

If inhaled

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

In case of skin contact

Wash off with soap and plenty of water. Consult a physician.

In case of eye contact

Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

If swallowed

Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

4.2 Most important symptoms/effects, acute and delayed

Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)

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

Airway protection. Ensure that a clear airway exists. Intubate the patient and aspirate the secretions with a large-bore suction device if necessary. Administer oxygen by mechanically assisted pulmonary ventilation if respiration is depressed. Improve tissue oxygenation as much as possible before administering atropine, to minimize the risk of ventricular fibrillation. In severe poisonings, it may be necessary to support pulmonary ventilation mechanically for several days. /N-methyl carbamate insecticides/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Waterspray is preferable, but dry chemical, CO2, foam can be used.

5.2 Specific hazards arising from the chemical

Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. (ERG, 2016)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.

6.3 Methods and materials for containment and cleaning up

10.Stability and reactivity

10.1 Reactivity

no data available

10.2 Chemical stability

Formulated material (80%) is stable at temperatures below 40°C. In aqueous solution at 25°C the half-life is 48 days at ph 5; 81 hours at ph 7; and 45 minutes at ph 9. Under ph 5 bendiocarb slowly degrades to pyrogallol and acetone. On non-absorptive surfaces and at low humidity it resists oxidation. It undergoes photo-oxidation in direct sunlight.

10.3 Possibility of hazardous reactions

BENDIOCARB is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill); Conditions: freshwater, flow through; Concentration: 1650 ug/L for 96 hr (95% confidence interval: 1470-1850 ug/L) /96% purity
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea, first instar larvae); Conditions: freshwater, static; Concentration: 29.2 ug/L for 48 hr (95% confidence interval: 23.5-35.7 ug/L); Effect: intoxication, immobilization /96% purity
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Both carbofuran and trimethacarb cross condition soil for the enhanced biodegradation of bendiocarb. 96% of added bendiocarb (initial concentration 10 ug a.i./g soil) was degraded after 14 days in a Drummer-Catlin soil mixture (pH 5, moisture holding capacity of 22.9 meq/100g) pretreated twice with carbofuran (10 mg a.i./g soil); within 42 days the bendiocarb loss under these conditions was 98%. Similar results for the biodegradation of bendiocarb were obtained for trimethacarb pretreated soils under the same conditions. Soil which was not pretreated showed only a 2% loss of bendiocarb within 14 days, 18% loss within 28 days, and 48% loss within 42 days(1). Seven soils with differing pesticide histories were treated separately with radioactive bendiocarb (14C, 5 mg bendiocarb/mL) and incubated for four weeks at 25°C. Three soils without a previous history of carbamate pesticide use over the previous 10 years gave 34.6%, 30.4%, and 47.2% bendiocarb remaining. Two soils with carbofuran applied over the last two years had 0.9% and 1.6% bendiocarb remaining. One soil which had received carbofuran in the previous year and mixed carbamate and organophosphorus insecticides every other year for 10 years with alternate years untreated had 1.3% bendiocarb remaining. And one soil which had received cloethocarb for the previous four years had 0.9% bendiocarb remaining(2). These results suggest that bendiocarb is rapidly degraded in soil which had been previously exposed to carbamate pesticides(SRC). A mean soil half-life of 12 days (3 day minimum and 21 day maximum) has been reported(3).

12.3 Bioaccumulative potential

An estimated BCF of 6 was calculated in fish for bendiocarb(SRC), using a log Kow of 1.70(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Koc values of 28 to 40 were reported for bendiocarb and its hydrolysis product 2,2-dimethyl-1,3-benzodioxol-4-ol(1); Koc values of 200(2) and 575(3) have also been reported in soil. According to a classification scheme(4), this range of Koc values suggest that bendiocarb is expected to have moderate to very high mobility in soil. While laboratory studies show a high degree of mobility, field studies indicate that parent bendiocarb generally degrades before leaching through the soil(5).

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.
