4.First-aid measures
4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water. Consult a physician.
In case of eye contact
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
This compound is toxic by all routes of exposure. The dangerous single oral dose of dinitro-o- cresol, a structurally similar compound, is estimated to be about 29 mg/kg. (EPA, 1998)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Supportive treatment and hyperthermia control. There is no specific antidote to poisoning with nitrophenolic or nitrocresolic herbicides. Treatment is supportive in nature and includes oxygen, fluid replacement, and temperature control. Reduce elevated body temperature by physical means. Administer sponge baths and ice packs, and use a fan to promote air flow and evaporation.7 In fully conscious patients, administer cold, sugar-containing liquids by mouth as tolerated. /Nitrophenolic and nitrocresolic herbicides/
5.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
If material on fire or involved in fire: Do not extinguish unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, carbon dioxide, or dry chemical. /Dinitrophenol solution/
5.2 Specific hazards arising from the chemical
When heated to decomposition it emits toxic nitrogen oxide fumes. (EPA, 1998)
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautions
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
6.3 Methods and materials for containment and cleaning up
Water spill: Use natural barriers or oil spill control booms to limit spill travek. Use surface active agent (eg detergent, soaps, alcohols) if approved by EPA. Inject "universal" gelling agent to solidify encircled spill and increase effectiveness of booms. If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. /Dinitrophenol solutions/
7.Handling and storage
7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

Eye/face protection
Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. 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.
Respiratory protection
Wear dust mask when handling large quantities.

10.1 Reactivity
no data available
10.2 Chemical stability
Stable in neutral, acidic and alkaline media.
10.3 Possibility of hazardous reactions
Nitrophenolates, such as DINOTERB, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups. Severe explosion hazard when dry.

12.2 Persistence and degradability
AEROBIC: In a mono-pesticide solid aqueous suspension biodegradation test, with a starting concentration of 20 mg/L, dinoterb had a half-life of 68 days(1). When mixed with other pesticides in the same test the half-life increased to 198 days. In a mono-pesticide unsaturated soil batch biodegradation test dinoterb had a half-life of 46 days(1).
12.3 Bioaccumulative potential
A BCF of 25 was reported for dinoterb, test conditions not specified(1). According to a classification scheme(2), this BCF value suggests bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of dinoterb has been reported to be 98, measured in alluvial sandy soil (7.8% clay, 30% silt, 62.2% sand, 0.64% organic carbon)(1). According to a classification scheme(2), this Koc value suggests that dinoterb is expected to have high mobility in soil. The pKa values of 4.8(3) and 5.0(4) indicate that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(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.
