Specific Hazards Arising from the Chemical
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Advice for firefighters
In case of fire in the surroundings, use appropriate extinguishing media.
Personal precautions, protective equipment and emergency procedures
Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. 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
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
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
Keep in a well-ventilated room. Well closed. Separated from food and feedstuffs. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.
Control parameters

STOT-single exposure
The substance is severely irritating to the eyes. The substance is irritating to the respiratory tract. The substance is mildly irritating to the skin. Inhalation at high concentrations and ingestion of large amounts may cause effects on the lungs, kidneys, liver and cardiovascular system. This may result in impaired functions and tissue lesions including haemorrhage and lung fibrosis. Exposure to high concentrations could cause death. Medical observation is indicated. The effects may be delayed.
STOT-repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the nails. This may result in nail damage.
Aspiration hazard
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

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.

Other Information
The toxicological information is the same for paraquat (CAS 4685-14-7).Depending on the degree of exposure, periodic medical examination is suggested.The symptoms of lung fibrosis (shortness of breath, laboured breathing) do not become manifest until several days.Rest and medical observation are therefore essential.Do NOT take working clothes home.Carrier solvents used in commercial formulations may change physical and toxicological properties.If the substance is formulated with solvents also consult the ICSCs of these materials.
