|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames.||Use water spray, foam, powder, carbon dioxide.|
|EXPOSURE||PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!|
|Inhalation||Pupillary constriction, muscle cramp, excessive salivation. Muscle twitching. Dizziness. Headache. Sweating. Laboured breathing. Unconciousness.||Use local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer for medical attention. See Notes.|
|Skin||Protective gloves.||Remove contaminated clothes. Rinse skin with plenty of water or shower.|
|Eyes||Redness. Blurred vision.||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. Convulsions. Diarrhoea. Nausea. Vomiting. Weakness. Further see Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention.|
|PACKAGING & LABELLING|

|The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds and 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.|
Methomyl is a mixture of (Z)- and (E)-isomers.
If the pesticide is present in a formulation containing hydrocarbon solvents, vomiting should not be induced.
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.
Do NOT take working clothes home.
Depending on the degree of exposure, periodic medical examination is suggested.
