SECTION 2: Hazards identification

Irritating to eyes and skin. 4. First aid measures  Eye contact: Irrigate thoroughly with water for at least 10 minutes. OBTAIN MEDICAL ATTENTION.  Inhalation: Remove from exposure, rest and keep warm. In severe cases obtain medical attention.  Skin contact: Wash off skin thoroughly with water. Remove contaminated clothing and wash before re-use. Unless contact has been slight, OBTAIN MEDICAL ATTENTION.  Ingestion: Wash out mouth thoroughly with water and give plenty of water to drink. OBTAIN MEDICAL ATTENTION. 5. Fire-fighting measures Special risks: Not combustible. May evolve toxic fumes in fire. (sulphur oxides) Suitable extinguishing media: To suit environment. 6. Accidental release measures Wear appropriate protective clothing. Absorb on an inert absorbent, (e.g. Spillage absorption granules), transfer to a suitable container and arrange removal by Disposal Company. Wash site of spillage thoroughly with water and detergent. For large spillages liquids should be contained with sand or earth and both liquids and solids transferred to salvage containers. Any residues should be treated as for small spillages. 7. Handling and storage Handling: Wash hands and face thoroughly after working with material. Contaminated clothing should be removed and washed before re-use.
