SECTION 4: First aid measures

Description of necessary first-aid measures

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.

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)

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

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Poisons A and B

SECTION 5: Firefighting measures

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)

Specific hazards arising from the chemical

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. For UN3508, be aware of possible short circuiting as this product is transported in a charged state. (ERG, 2016)

Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

SECTION 6: Accidental release measures

Personal precautions, protective equipment and emergency procedures

Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.

Environmental precautions

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

Methods and materials for containment and cleaning up

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a POTW is acceptable only after review by the governing authority. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must meet Hazardous Material Criteria for disposal.

SECTION 10: Stability and reactivity

Reactivity

Hydrolysis rapidly occurs under alkaline conditions

Chemical stability

Stable up to 50 degrees C. Stable in neutral and weakly acidic media.

Possibility of hazardous reactions

A halogenated dicarboximide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Persistence and degradability

Vinclozolin is persistent in soil, being only partly degraded by soil microorganisms(1). When vinclozolin was applied to a previously untreated sandy loam soil (17.7% clay, 67.5% sand, 14.8% silt, pH 6.5, 1.05% organic C), less than 10% of the applied dose remained after 40 days(2). Following re-treatment at 50 days, less than 10% remained 23 days later, and when treated for the third time, less than 10% remained after just 2 days(2). In a clay loam soil (19.1% clay, 68.9% sand, 12.0% silt, pH 6.3, 0.68% organic C), times for 50% loss of the first, second, and third applications of vinclozolin were about 7, 4, and 2.5 days, respectively(2). In a third soil (8.6% clay, 75.7% sand, 15.7% silt, pH 5.0, 1.13% organic carbon), 47% of the initial dose remained after 140 days(2). When treated for the first time after pre-incubation with the fungicide, about 60% of the vinclozolin was recovered after 69 days(2). During an 80 day incubation period, only limited degradation of vinclozolin was observed in soils at pH 4.3 and 5.0(3). In soil with pH 5.7, the time for 50% loss of vinclozolin was about 75 days; times for 50% degradation following the first, second, and third application of vinclozolin were 70, 30, and 6 days, respectively(3). In soil with pH 6.5, the times for 50% degradation following the first, second, and third applications were 30, 22, and 7 days, respectively(3). After 14 days incubation in soil with no pretreatment, and soil pretreated with iprodione, vinclozolin, myclozolin, and procymidone, the concentration of vinclozolin was 5.45, 5.50, 0.05, 5.39, and 5.45 mg/kg, respectively; after 28 days the concentration of vinclozolin was 2.44, 2.44, 1.89, 0, 2.37, and 2.31 mg/kg, respectively(4). In Patumahoe clay loam, the time for 50% loss of vinclozolin following the first, second, and third soil application of the fungicide was 22, 3.5, and 1 days, respectively(5). For five different types of field soil (clay loam, silt loam, loam, sandy loam and sandy clay loam) ranging in pH from 7.98 to 8.35, 90% degradation was reached after one, two and three applications of vinclozolin in approximately 35, 21 and 7 days, respectively(6).

Bioaccumulative potential

One study predicted worst-case BCF values in fish for vinclozolin of 60 and 1,260(1), respectively, on a wet weight basis with 5% lipid, and on a lipid basis predicted from the log Kow of 3.10(2) if no metabolism occurs or is negligible(1). Another study calculated a BCF range of 78 to 112(3). An estimated BCF of 52 was calculated in fish for vinclozolin(SRC), using a log Kow of 3.10(2) and a regression-derived equation(4). According to a classification scheme(5), these BCF data suggest the potential for bioconcentration in aquatic organisms is moderate to very high(SRC), provided the compound is not metabolized by the organism(SRC).

Mobility in soil

In laboratory tests, vinclozolin migrated through Ottowa sand more deeply compared to aquatic hapludult soil, where all vinclozolin mass was retained in the upper 5 cm under high (6.7 mm) and low (3.1 mm) rain events(1). One review suggested Koc values range from 100 to 735(2). A Koc value of 1,570 was determined in a Chalmers silty clay loam(3). According to a classification scheme(4), these disparate Koc values suggest that vinclozolin is expected to range from low to high mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

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
