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.

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

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

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.

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)

Skin decontamination. Wash skin with soap and water . Eye contamination should be removed by prolonged flushing of the eye with copious amounts of clean water or saline. If irritation persists, obtain specialized medical treatment. Sensitization reactions may require steroid therapy. Haloaromatic substituted ureas

Wear self contained breathing apparatus for fire fighting if necessary.

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)

Wear self-contained breathing apparatus for firefighting if necessary.

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.

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.

Use personal protective equipment. Avoid dust formation. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust.

Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Store in a dry location.

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.

Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).

Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

AEROBIC: The ultimate biodegradation rate constant of diflubenzuron at 28 deg C was measured to be 0.037 day-1 in a sandy loam and 0.026 day-1 in muck soil(1) which correspond to half-lives of about 19 and 27 days, respectively(SRC). In the same study, 80-87% diflubenzuron (initial concentration of 10 ppm) remained in sterile soil after 12 weeks; therefore, soil microorganisms play a major role in the disappearance of diflubenzuron(1). Based on several screening tests, the biodegradation half-life averaged 2.4 days using freshwater sediment and 15 days in sterile freshwater sediment(2). Biodegradation half-lives averaged 14 and 32 days using marine-sediment and marine-water, respectively(2). There were no differences in the disappearance of diflubenzuron from sewage water, whether boiled or unboiled; a 14-15% reduction from 0.1 ppm initial concentration was observed immediately following treatment. Reductions of 30% at 6 hr and 42% at 24 hr were probably due to adsorption(3). When applied to a sandy loam soil under aerobic conditions at 24 deg C, diflubenzuron had half-lives ranging from 2-14 days (depending on soil texture) with the major degradates being 4-chlorophenyl urea and CO2(4); three minor degradates were 2,6-difluorobenzoic acid, 2,6-difluorobenzamide, and 4-chloroaniline(4).

Reported bioconcentration factors for diflubenzuron in bluegill sunfish (Lepomis macrochirus) ranged from 34 to 200 for fillet and 78 to 360 for whole fish(1). According to a classification scheme(2), these BCF ranges suggest the potential for bioconcentration in aquatic organisms is moderate to high. Diflubenzuron depurates rapidly in fish tissue(1); the depuration rate indicates a rapid decrease (99%) of accumulated residues in tissue during a 14-day depuration period.

Diflubenzuron has reported Koc values of 6,790 and 10,600(1). According to a classification scheme(2), these Koc values suggest that diflubenzuron is expected to be immobile in soil. Binding to soil is an important transport process for diflubenzuron based on soil Kd values for sand clay, silty clay loam, silt loam, sand loam, sandy clay loam, clay, clay hydrosoil, and peat hydrosoil of 40, 40, 20, 25, 130, 110, 150, and 3500, respectively(3). Diflubenzuron is classified as relatively immobile in soil based on Rf values were 0.01, 0.07, 0.14, and 0.34 for silty clay loam, clay loam, and two sand loam soils, respectively(3). In field tests, diflubenzuron was not detectable below the 0-15 cm soil depth segment over a 60-day period(3). In water tank studies, diflubenzuron adsorbed to sediment showed no detectable diffusion from the sediment to water over a 204-day observation period(4).

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.

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.
