Generally speaking, solid molybdenum metal is considered relatively safe to handle and come into contact with in the short term. Molybdenum is a stable, inert metal that does not pose significant health risks through skin contact. However, as with any metal or material, it is important to follow basic safety practices to minimize potential risks:

1. Skin Protection: While molybdenum itself is not known to cause skin irritation or allergies, it is recommended to wear gloves when handling molybdenum or any metal to protect the skin from potential cuts, abrasions, or contamination.

2. Dust and Fume: When molybdenum is processed or machined, fine dust or particles are produced. In this case, appropriate respiratory protection and ventilation should be used to minimize inhalation of airborne particles.

3. Ingestion and Inhalation: As a general safety precaution, avoid ingestion or inhalation of molybdenum dust or particles. Proper hygiene, such as washing hands after handling molybdenum, can help prevent accidental ingestion.

It is important to note that while solid molybdenum is relatively safe to handle, molybdenum compounds and dust generated during processing or machining may have different properties and safety considerations. As with any material, it is important to follow proper safety guidelines and practices when handling molybdenum to minimize potential risks. If you have specific questions about handling molybdenum in a particular environment, it is recommended to consult the relevant safety data sheets and guidance for correct handling and safety precautions.
