5.Fire-fighting measures
5.1 Extinguishing media
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)
5.2 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)
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
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.
6.3 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.
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.
7.2 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 ... .

12.2 Persistence and degradability
... MICROBIAL BREAKDOWN HAS BEEN DEMONSTRATED.
12.3 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).
12.4 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).
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.
