If inhaled

Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.

Following skin contact

Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Following eye contact

Rinse with pure water for at least 15 minutes. Consult a doctor.

Following ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

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

SECTION 5: Fire-fighting measures

5.1 Suitable extinguishing media

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE INVOLVING TANKS: Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Benfluralin is metabolized with a half-life of 20 to 86 days under aerobic soil conditions(5). Biodegradation of benfluralin in soil occurs via oxidative and reductive pathways(1). Oxidation classically occurs in aerobic soils and reduction in anaerobic soils. However, in flooded field soils, both oxidation and reduction products have been observed(1). In field soil, oxidative biodegradation of benfluralin leads to dealkylation products followed by reduction of nitro group to amino products(1,4). Rates of biodegradation of benfluralin is dependent on soil temperature and moisture content and the rate is faster at 30 deg C compared to 4 deg C, and in dry soil compared to water-saturated field soils(2-3). The biodegradation is faster in soils containing higher organic carbon contents(3,5). The biodegradation half-lives of benfluralin in a loam and a sandy loam soil were 0.7 month and 1.5 months, respectively, at 30 deg C(3).

12.3 Bioaccumulative potential

The whole body BCF value measured in fish was 1,580(1). According to a classification scheme(2), this BCF value suggests the potential for bioconcentration of benfluralin in aquatic organisms is very high(SRC).

12.4 Mobility in soil

Soil adsorption (Kd) coefficients for benfluralin in 10 Wisconsin soils ranged from 4.2-30.3, with a mean value of 16.7 (1). Other investigators have reported Koc values of 10,700(2), 10,715(4), and 9,000(3). Benfluralin was much more highly adsorbed to soil than other dinitroaniline herbicides(5). In soil thin layer chromatography experiments, the Rf (retention factor) range was 0-0.03 for benfluralin(6). Therefore, it was concluded that benfluralin was immobile in soil(6). In the EPA Registration Eligibility Decision document for benfluralin, it was reported that the Koc ranged from 9,840-11,660(7). According to a classification scheme(8), this range of Koc values indicates that benfluralin is expected to have no mobility in soil(SRC).

12.5 Other adverse effects

no data available

SECTION 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.
