First-aid measures

After inhalation:  Remove person to fresh air. If symptoms persist, call a physician.

After skin contact: Wash with water and soap. When skin irritation occurs: seek medical advice resp. medical attendance.

After eye contact: Rinse thoroughly with plenty of water. If eye irritation persists, consult a specialist.

After ingestion: Rinse mouth and drink plenty of water. Consult a doctor.

Fire-fighting measures

Extinguishing agents:

- Suitable extinguishants: metal fire powder extinguisher, dry sand, dry sodium chloride

- Unsuitable extinguishants: water, CO2

Special hazards arising from the substance or mixture In case of fire, product may form:

- Carbon monnoxide

- Carbon dioxide: CO2 (gas) is heavier than air. Asphyxiating at high concentrations.

Advice for firefighters

Special protective measures and equipment: Wear self-contained breathing apparatus.

- Molybdenum trioxide

Accidental release measures

Personal Precautions:

- Remove all sources of ignition.

- Avoid formation and sedimentation of dust.

- Use personal protective equipment.

Environmental Precautions:

No special environmental precautions required.

Methods and material for containment and cleaning up:

Cleaning methods: Pick up mechanically. Avoid dust formation. Fill in labelled and locakble container

Handling and storage

Precautions for safe handling

- Handling Precautions: Avoid dust formation. Provide adequate ventilation during handling and transfer of substance, if necessary with vapour extraction at the workplace.

- Precautions against fire and explosion: Keep away from open flames, hot surfaces and ignition sources. Take precautionary measures against static discharges. Dust from the production process may form an explosive dust-air mixture.

- Hygiene measures: Handle in accordance with good industrial hygiene and safety practice. Store work clothes separately.

Conditions for safe storage, including any incompatibilities :

- Requirements for storage rooms and vessels: No special requirements.

- Further information concerning storage conditions: Store dry in tightly locked containers.

- Indication for Combined Storage: Comply with VCI standards for combined storage.

- Storage category: 11, flammable solids
