Most important symptoms/effects, acute and delayed
Extremely toxic: Probable oral lethal dose is 5-50 mg/kg; between 7 drops and 1 teaspoonful for 70 kg person (150 lb.). (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Rats poisoned by consumption, inhalation, or skin exposure to herbicides dinitroisopropyl-(dnpp) and dinitrobutylphenol (dnbp) ... liver, kidney, spleen and blood contained metabolites.
SECTION 5: Firefighting measures
Suitable extinguishing media
This is a dinitrophenol herbicide. (Non-Specific -- Dinitrophenol, Flammable Solid) Wear self-contained breathing apparatus and full protective clothing. If fire becomes uncontrollable, evacuate for a radius of 5000 feet. This material is a dinitrophenol herbicide. (Non-Specific -- Dinitrophenol, Flammable Solid) Extinguish by flooding with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. (EPA, 1998)
Specific hazards arising from the chemical
This is a dinitrophenol herbicide. (Non-Specific -- Dinitrophenol, Flammable Solid). It is dangerously explosive. When not water wet it is a high explosive. Dry, the material is easily ignited and it will burn very vigorously. On decomposition, nitro compounds such as this emit toxic fumes. Appear to be stable in acid solution, but are susceptible to decomposition by ultraviolet radiation in alkaline solution. (EPA, 1998)
Special protective actions for fire-fighters
Use water spray, foam, powder, carbon dioxide. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Environmental precautions
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Spillages of pesticides at any stage of their storage or handling should be treated with great care. Liquid formulations may be reduced to solid phase by evaporation. Dry sweeping of solids is always hazardous: these should be removed by vacuum cleaning, or by dissolving them in water, or other solvent in the factory environment.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames. 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.
Conditions for safe storage, including any incompatibilities
Provision to contain effluent from fire extinguishing. Separated from bases and food and feedstuffs. Cool. Keep in a well-ventilated room. Well closed. Store in an area without drain or sewer access.MATERIALS WHICH ARE TOXIC AS STORED OR WHICH CAN DECOMPOSE INTO TOXIC COMPONENTS ... SHOULD BE STORED IN A COOL WELL VENTILATED PLACE, OUT OF THE DIRECT RAYS OF THE SUN, AWAY FROM AREAS OF HIGH FIRE HAZARD, AND SHOULD BE PERIODICALLY INSPECTED. INCOMPATIBLE MATERIALS SHOULD BE ISOLATED .

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces toxic fumes including nitrogen oxides. The solution in water is a weak acid. Attacks many metals in the presence of water.
Chemical stability
2-year shelf life minimum; dow general weed killer: 2-year shelf life minimum.
Possibility of hazardous reactions
DINOSEB is a powerful oxidizing agent. (NTP, 1992). It is dangerously explosive. When not water wet it is a high explosive. Dry, the material is easily ignited and it will burn very vigorously. On decomposition, nitro compounds such as this emit toxic fumes. Appear to be stable in acid solution, but are susceptible to decomposition by ultraviolet radiation in alkaline solution. [EPA, 1998].

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 Salvelinus namaycush (Lake trout) 44 ug/l 96 hr @ 10 deg C (95% confidence limit 38-51 ug/l), wt 0.3 g /Technical material, 95.8%/ /Static bioassay
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
Microbial breakdown has been demonstrated.
Bioaccumulative potential
A bioconcentration factor (BCF) of 68 for dinoseb was estimated from its water solubility (50 mg/L)(1). A BCF of this magnitude suggests that dinoseb will not bioconcentrate significantly(SRC).
Mobility in soil
The measured soil-sorption coefficient (Koc) of dinoseb is 124(1). A Koc of this magnitude suggests that dinoseb will be highly mobile in soil and may leach to groundwater. A much higher Koc value of 6607 wa obtained at a buffered pH of 3(2). It appears that soil sorption may be pH dependent and at low pH adsorption may be stronger. It has been shown, however, that p-nitrophenol adsorbs strongly to clays through an interaction between the nitro group and the water molecules or metallic cations in the clay(3). Dinoseb may similarly bind to clays at low pH. Experiments with soil thin layer chromatography showed that dinoseb was intermediate to very mobile in silt loam sand loam and silty loam soils(4).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
