|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.||In case of fire in the surroundings, use appropriate extinguishing media.|
|EXPLOSION||Risk of fire and explosion if formulations contain flammable/explosive solvents.||In case of fire: keep drums, etc., cool by spraying with water.|
|EXPOSURE||AVOID ALL CONTACT! AVOID EXPOSURE OF BREASTFEEDING WOMEN!|
|Inhalation||Cough. Sore throat. Further see Ingestion.||Avoid inhalation of dust.||Fresh air, rest. Refer for medical attention.|
|Skin||MAY BE ABSORBED!||Protective gloves. Protective clothing.||Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .|
|Eyes||Redness.||Wear face shield or eye protection in combination with breathing protection if powder.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Headache. Nausea. Vomiting. Diarrhoea. Dizziness. Tremor. Convulsions.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Give a slurry of activated charcoal in water to drink, but NOT if convulsions occur. Refer immediately for medical attention.|
|PACKAGING & LABELLING|
|Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance, chemical protection suit including self-contained breathing apparatus and protective gloves. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable non-metallic containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT wash away into sewer.||
Do not transport with food and feedstuffs.

|The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in fish and seafood. The substance may cause long-term effects in the aquatic environment. 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.|
Boiling point, melting point and vapour pressure are depending on isomeric composition.
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of convulsions do not become manifest until 0.5 to several hours.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Occupational Exposure Limits : MAK value is for technical mixture of alpha and beta isomers (0.5 mg/m3=(Conc.alpha-HCH divided by 5) + Conc beta-HCH).
