SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

...Compatible with most common organic pesticides as well as aqueous nitrogen fertilizers. /Velsicol/

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)

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)

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. Avoid inhalation of asbestos dust. SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area. SMALL SPILL: Pick up with sand or other non-combustible absorbent material and place into containers for later disposal. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Cover powder spill with plastic sheet or tarp to minimize spreading. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2016)

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing will only provide limited protection. (ERG, 2016)|Chemical-resistant footwear plus socks. Long-sleeved shirt and long pants. Protective eyewear. Waterproof gloves.

Contain liquid spill with absorbent material, collect in a suitable waste container. Wash effected area with water and detergent. Keep wash water out of drains. Whenever possible, all product or absorbent material should be used/applied according to label instructions and quantities. Otherwise dispose of at an approved chemical waste facility.

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.|SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Dicamba is a mildly corrosive sensitizing agent, and skin irritation or burns can follow dermal exposure. Eye contact can result in a temporary clouding of the cornea that may persist for 5 to 7 days. /Dicamba/

/AQUATIC SPECIES/ Chronic toxicity of the herbicide Banvel-D (dicamba; dimethylamine salt of 2-methoxy-3,6-dichlorobenzoic acid) was studied in Daphnia magna. ...Marked decrease of survival rate was recorded in variants with Banvel-D at 67 mg/L. Banvel-D at 67 mg/L also reduced fertility of Daphnia. Abnormal development was recorded in Daphnia exposed to Banvel-D at 11.5-45 mg/L (generation III and IV). Banvel-D at 23 and 45 mg/L resulted in deterioration of the physiological state, disturbances of embryogenesis and a decreased life span.

Dicamba is readily absorbed following ingestion, but only minimal absorption occurs after dermal exposure. Following ingestion, dicamba appears to be rapidly and nonselectively distributed to most organ systems. Most animal studies indicate greater than 90 % of the original dose ultimately undergoes urinary excretion. Small amounts of dicamba are excreted in the feces and have been shown to represent true elimination (indicated after sc administration ) and excretion of unabsorbed herbicide (following oral exposure). ... Elimination occurs rapidly, and there is no evidence of bioaccumulation in mammalian systems. /Dicamba/

Dicamba is excreted mostly in unmetabolized form but may also be conjugated with glucoronic acid or glycine. /Dicamba/|Holstein dairy cow was fed by catheter 5 ppm of Banvel-D (2-methoxy-3,6-dichlorobenzoic acid) for 4 days based on 22.7 kg daily feed ration. ...No residues were detected in either the milk or the feces; during the first 4 days of the feeding trial, only traces (not quantitatively measurable) were found of Banvel-D in the feces. The urine accounted for 73% of the excretion of the intact herbicide. From day 2 through day 7, the urinary concentrations were 3.4, 4.6, 4.3, 4.2, 4.1 and 0.1 ppm, respectively.

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)

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. (ERG, 2016)

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/|Ingestions of these herbicides are likely to be followed by vomiting and diarrhea due to the irritant properties. ... Activated charcoal is probably effective in limiting irritant effects and reducing absorption of most or all of these herbicides. Aluminum hydroxide antacids may be useful in neutralizing the irritant actions of mose acidic agents. Sorbitol should be given to induce catharsis if bowel sounds are present and if spontaneous diarrhea has not already commenced. Dehydration and electrolyte disturbances may be severe enough to require intravenous fluids. There are no specific antidotes for poisoning by these herbicides. /Other Herbicides/|If serious dehydration and electrolyte depletion have occurred as a result of vomiting and diarrhea, monitor blood electrolytes and and fluid balance and administer intravenous infusions of glucose, normal saline ringer's solution, or ringer's lactate to restore extracellular fluid volume and electrolytes. Follow this with oral nutrients as soon as fluids can be retained. Fluids serve to support excretion of the toxicants. Supportive measures are ordinarily sufficient for successful management of excessive exposures to these herbicides. /Other Herbicides/
