|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames.||Use foam. Use powder. Use carbon dioxide.|
|EXPOSURE||STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!|
|Inhalation||Dizziness. Pupillary constriction. Muscle cramps. Excessive salivation. Sweating. Laboured breathing. Unconciousness. Symptoms may be delayed. See Notes.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer for medical attention.|
|Skin||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .|
|Eyes||Wear safety goggles or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Abdominal cramps. Diarrhoea. Nausea. Vomiting. Further see Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest. Refer for medical attention .|

|The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to bees. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.|
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
If the substance is formulated with solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
