| Brandbekämpfung | Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. |
| Erste-Hilfe-Maßnahmen | Fresh air, rest. Refer for medical attention.Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention . |
| Sichere Lagerung | Separated from strong bases. Store in an area without drain or sewer access. |
| Verschüttetes entsorgen | Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment. |
| Eye Prevention | Wear safety goggles or eye protection in combination with breathing protection. |
| Fire Prevention | NO open flames. |
| Inhalation Risk | A harmful concentration of airborne particles can be reached quickly when dispersed. |
| Skin Prevention | Protective gloves. |
| Exposure Prevention | PREVENT DISPERSION OF DUST! |
| Ingestion Prevention | Do not eat, drink, or smoke during work. |
| Inhalation Prevention | Use ventilation, local exhaust or breathing protection. |
| Effects of Long Term Exposure | Repeated or prolonged contact may cause skin sensitization. |
| Expositionspfade | The substance can be absorbed into the body by inhalation of its aerosol. |
