First Aid: Eye:
Immediately flush eyes with plenty of flowing water for 10 to 15 minutes holding eyelids apart.
Consult an ophthalmologist.
First Aid: Skin:
Wash immediately with plenty of water and soap for at least 15 minutes. Remove contaminated
clothing and shoes. Wash contaminated clothes before reuse. Call a physician.
First Aid: Ingestion:
Wash out mouth with water provided person is conscious. Call a physician.
First Aid: Inhalation:
Remove casualty to fresh air and keep warm and at rest. If breathing is irregular or stopped,
administer artificial respiration. Call a physician.
Hints for Physician: Treatment Treat symptomatically.

Extinguishing Media Suitable: Foam, dry extinguishing powder, carbon dioxide (CO2), water spray
jet
Hazards During Fire-Fighting: Toxic fumes
Protective Equipment for Fire-Fighting: Wear a self-contained breathing apparatus and chemical
protective clothing.
Fire-Fighting/Further Advice: Do not inhale explosion and combustion gases. Collect contaminated
fire extinguishing water separately. This must not be discharged into drains. Move undamaged
containers from immediate hazard area if it can be done safely

Personal Precautions: Wear breathing apparatus if exposed to vapours/dusts/aerosols. Provide
adequate ventilation.

Environmental Precautions: Do not allow to enter into soil/subsoil. Do not allow to enter into
surface water or drains. Ensure all waste water is collected and treated via a waste water treatment
plant.
Methods for Cleaning or Taking Up: Not available
Further Accidental Release Measures: Collect in closed and suitable containers for disposal. Clear
contaminated areas thoroughly. Ventilate affected area.

Handling:
Handling advice: Avoid contact with skin, eyes and clothing. Avoid ingestion and inhalation. Avoid
prolonged or repeated exposure. Remove contaminated clothing and wash before reuse. Wash
thoroughly after handling.
Storage:
Storage temperature: store at 10°C – 25°C
