Pure tungsten is generally considered safe to handle and use, but due to its potential hazards, certain precautions should be taken:

Dust and Fumes: When tungsten is ground or processed, airborne dust and fumes are created that can be dangerous if inhaled. Proper ventilation and personal protective equipment such as respiratory protection should be used when handling these forms of tungsten. Skin contact: Direct skin contact with tungsten is generally not hazardous, but prolonged exposure to tungsten powder or compounds may cause skin irritation in some people. Ingestion: Ingestion of tungsten is considered unsafe. As with any metal or alloy, tungsten should not be ingested, and food or drink should not come into contact with surfaces contaminated with tungsten. Occupational Safety: In industrial settings where tungsten is processed or used, appropriate occupational safety measures should be taken to minimize exposure to tungsten dust and fumes.

Overall, pure tungsten is considered relatively safe to handle, but it is important to follow safety guidelines and take appropriate precautions to prevent potential hazards. If tungsten is used in an industrial or professional environment, it is recommended to consult an occupational health and safety expert for specific guidance.
