Specific Hazards Arising from the Chemical
Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Advice for firefighters
Use water, foam, carbon dioxide, powder.
Personal precautions, protective equipment and emergency procedures
Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Environmental precautions
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.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
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
Dry. Well closed. Keep in a well-ventilated room. Store in an area without drain or sewer access.

Information on basic physicochemical properties
- Physical stateLiquid
- ColourClear, colorless
- Odour
no data available
- Melting point/freezing point
Ca. 91 °C. Atm. press.:1 atm.
- Boiling point or initial boiling point and boiling range
Remarks:The substance shows endothermic reactions above 65°C. This can be attributed to rearrangements in the crystal structure due to the presence of water, which evaporates at elevated temperatures. Boiling temperature in its classic sense cannot be determined.
- Flammability
no data available
- Lower and upper explosion limit/flammability limit
no data available
- Flash point
60.5°C
- Auto-ignition temperature
Remarks:An endothermic effect was observed at 78 °C, followed by exothermic decomposition at 244 °C. The maximum reaction temperature was 258 °C.
- Decomposition temperature
no data available
- pH
no data available
- Kinematic viscosity
no data available
- Solubilityabout 35 % in water, less soluble in organic solvents. However, the free acid, diethyldithiocarbamic acid, is readily soluble in organic solvents and less soluble in water. Thus, on acidification of an aqueous solution of a diethyldithiocarbamate, the free acid can be extracted with chloroform or carbon tetrachloride. The distribution ratio is 2,360 for chloroform and 343 for carbon tetrachloride.
- Partition coefficient n-octanol/water
log Pow = <= -1.1. Temperature:20 °C.

STOT-single exposure
The substance is irritating to the skin, eyes and upper respiratory tract.
STOT-repeated exposure
See Notes.
Aspiration hazard
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.
Toxicity
- Toxicity to fish: LC50 - Poecilia reticulata - 1 640 μg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: LC50 - Daphnia magna - 0.91 mg/L - 48 h.

Disposal methods
ProductThe 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.
