Guidance on Safe Use

First-aid measures

- General advice:
- Following inhalation: Remove exposed person to fresh air if adverse effects are observed
- Following skin contact: Wash with soap and water. If skin irritation occurs, get medical attention
- Following eye contact: Any material that contacts the eye should be washed out immediately with water. If easy to do, remove contact lenses.
- Following ingestion: Treat symptomatically. Get medical attention
- Most important symptoms and effects: Not described

Fire-fighting measures

- Suitable extinguishing media: water, foam
- Unsuitable extinguishing media: oxidant agents
- Special hazards arising from the substance or mixture: When heated, hazardous gases could be released.
- Advice for fire fighter: Wear full protective fire gear including self-containing breathing apparatus operated in the positive pressure mode with full facepiece, coat, pants, gloves and boots

Accidental release measures

- Personal precautions: wear protective equipment, avoid skin and eye contact with the product.
