1. Protective measures: When handling silicon nitride, appropriate personal protective measures should be taken, including wearing gloves, goggles, and a mask. This helps prevent direct contact and inhalation of silicon nitride particles.

2. Ventilation: Good ventilation should be ensured in areas where silicon nitride is handled and handled to reduce possible inhalation risks. It is necessary to use chemical ventilation equipment or keep the work area well ventilated.

3. Avoid the generation of dust: Try to avoid the generation of silicon nitride dust, because inhaling fine silicon dust may be harmful to the respiratory system. Take measures such as wet processing, use of vacuum equipment, etc. to reduce dust generation.

4. Storage Note: Silicon nitride should be stored in a dry, well-ventilated place, away from moisture and moisture. Avoid contact of silicon nitride with moisture to prevent its performance from being affected.

5. Avoid contact with strong acids and alkalis: Silicon nitride has certain chemical stability against strong acids and alkalis, but it is best to avoid direct contact with these substances to ensure the long-term stability of the material.

6. Pay attention to high temperatures: Silicon nitride has a high melting point and high temperature resistance, but it may still change under extreme high temperatures. In high temperature applications, be sure to use within the temperature range of the material to prevent performance degradation.

7. Compliance: In special application areas, such as semiconductor manufacturing, ensure compliance with relevant industry standards and safety regulations.
