3. Hazards identification
Contact with combustible material may cause fire. Harmful if swallowed. Irritating to eyes.
4. First aid measures
- Eye contact: Irrigate thoroughly with water for at least 10 minutes. If discomfort persists, obtain medical attention.
- Inhalation: Remove from exposure, rest and keep warm. In severe cases obtain medical attention.
- Skin contact: Wash off thoroughly with soap and water. Remove contaminated clothing and wash before re-use. In severe
cases, 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:
May ignite combustible material. May explode if heated.
Suitable extinguishing media:
Water spray
6. Accidental release measures
Wear appropriate protective clothing.
If local regulations permit, transfer spillage into containers of water, stir to dissolve or suspend and run to waste, diluting greatly
with running water. Otherwise mix with wet sand, transfer to container and arrange removal by disposal company. As contact
with any oxidant can render organic matter (paper, wood, textiles) dangerously combustible, wash area of spillage and
contaminated clothing thoroughly with water.
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:
Change contaminated clothing. Wash hands after working with substance.
