Administrative data
First-aid measures
Skin:
After contact with skin, wash immediately with plenty of water and soap. Get medical attention if irritation occurs.
Inhalation:
Remove to fresh air, if not breathing give artificial respiration. If breathing is difficult, give oxygen and get immediate medical attention.
Eyes:
In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Ingestion:
Do not induce vomiting. If vomiting occurs naturally, have casualty lean forward to reduce the risk of aspiration. Seek medical attention immediately.
Fire-fighting measures
Suitable extinguishing media:
Water spray, foam, carbon dioxide, dry powder.
Hazardous combustion products:
In case of fire formation of tungsten trioxide (solid) .
Protective equipment for fire-fighting:
Wear self-contained breathing apparatus and chemical-protective clothing.
Accidental release measures
Personal precautions:
Wear suitable protective equipment. Avoid contact with skin and eyes.
Environmental precautions:
Do not empty into drains or water.
Methods for cleaning up and containment:
Take up mechanically. Fill into labeled, sealable containers. Avoid dust formation.
Handling and storage
Personal precautions:
Prevent formation of dust. Wear personal protective equipment. Avoid contact with eyes, skin and clothing. Wash thoroughly after
handling. Keep away from sources of ignition.
Technical measures:
Provide good ventilation (local exhaust) of the working area. Keep away from sources of heat and ignition.
Storage:
Keep container tightly closed in a dry, cool and well-ventilated place. Keep away from foodstuffs, drinks and tobacco.
