Laboratories dealing with nanomaterials should follow these best practices: 1. Labeling and Segregation: Clearly label all containers with nanomaterials and segregate them from other waste. 2. Personal Protective Equipment (PPE): Ensure that all personnel wear appropriate PPE, including gloves, masks, and lab coats. 3. Spill Management: Have protocols in place for managing spills, including the use of absorbents and proper disposal of contaminated materials. 4. Regular Audits: Conduct regular audits of waste management practices to ensure compliance and safety.
