IV. Hazard Identification

Indicators for Primary Routes of Entry
Skin: Yes
Eyes: Yes
Inhalation: Yes
Ingestion: Yes
Primary Routes of Entry: Inhalation, Skin, Ingestion
Effects of Overexposure: The acute toxicity is low. Consequently, inhalation or ingestion may result in localized lung or skin granulomas, and eye contact may cause particulate irritation.

V. First Aid Measures

General Emergency First-Aid Measures
Skin: Seek medical assistance immediately
Eyes: Seek immediate medical assistance
Oral: Seek medical assistance
Inhalation: Seek medical assistance

VI. Fire-Fighting Measures

Fire Extinguishing Media: CO₂, dry sand or dry chemical agents
Special Fire-Fighting Measures: Use a self-contained breathing apparatus
Unusual Fire and Explosion Hazards: Non-combustible. Given that it is safe, remove the germanium metal from the fire area.

VII. Handling and Storage

Precautions for Handling and Storage: Avoid inhalation of dust; avoid contact with skin and eyes; minimise exposure to air; store in a sealed container filled with argon gas or mineral oil.
