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 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)

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

Skin decontamination. Skin contamination should be treated promptly by washing with soap and water. Contamination of the eyes should be treated immediately by prolonged flushing of the eyes with large amounts of clean water. If dermal or ocular irritation persists, medical attention should be obtained without delay. /Other herbicides/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Thiocarbamates, such as cycloate, undergo rapid biodegradation(1,4). Cycloate was not mineralized in sewage or lakewater, but it was metabolized to organic products(2). When incorporated 3 inches deep into moist loam at a temperature of 70-80°C, an 83% loss of cycloate occurred in 70 days; at 40°C only 32% loss occurred(3). In dry soil incubated at 70-80°C, only 9% loss occurred(3). Autoclaving the soils greatly increased the persistence of cycloate indicating that microbial degradation is important(3). Cycloate does not decrease the number or biochemical activity of soil organisms(4). Using a continuous flow-through system and soil inoculum, 14C-labeled cycloate was up to 90% mineralized(5). Laboratory metabolism study using aerobic soil resulted in a half-life of 43 days; soil degradates include the sulfoxide and N-ethylcyclohexylamine, N-cyclohexyl-N-ethylformamide and N-ethyl-N-formyl-S- ethyl thiocarbamate(6).

12.3 Bioaccumulative potential

An estimated BCF of 190 was calculated for cycloate(SRC), using a log Kow of 3.88(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

The Koc of cycloate has been experimentally determined to be 345(1,2). The compound tends to sorb to soil under dry conditions and is not reversed if soil is later flooded(3). If already flooded, then cycloate desorbs readily and then volatilizes. Koc values of 500-800 have been reported(3). According to a classification scheme(4), these Koc values suggest that cycloate is expected to have moderate mobility in soil. Cycloate was found at a maximum depth of 6-9 inches in a leaching study using four different soils(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.
