Ingestion: No hazards which require special first aid measures.
Inhalation: Remove to fresh air. If symptoms persist, call a physician.
Fire-fighting measures
Suitable extinguishing media: Any
Specific hazards during firefighting: Fire may cause evolution of Carbon monoxide (CO) and Carbon dioxide (CO2)
Special protective equipment for firefighters: In the event of fire, wear self-contained breathing apparatus.
Further information: Prevent fire extinguishing water from contaminating surface
water or the ground water system.
Accidental release measures
Personal precautions: Use personal protective equipment. Avoid dust formation.
Environmental precautions: Do not flush into surface water or sanitary sewer system.

Handling and storage
Advice on safe handling: Avoid contact with skin, eyes and clothing. Measures must be taken to prevent dust explosion when processing in fine crystalline form. Avoid dust formation.
Advice on protection against fire and explosion: Take measures to prevent the build up of electrostatic charge. Keep away from open flames, hot surfaces and sources of ignition.
Hygiene measures: Use protective skin cream before handling the product. Wash hands and face before breaks and immediately after handling the product.
