In order to prevent toner from causing greater harm to the human body, when using toner and toner printers, you should take protective measures, including:

1. Purchase toner produced by regular manufacturers.

2. If we cannot determine the harm of toner, please reduce its use unless necessary, keep it away from the printer, and place it in a ventilated position.

3. Try not to add toner in crowded places or workplaces.

4. The replaced toner cartridges or toner cartridges need to be exchanged to the provider or handled normally to avoid secondary harm to others.

5. We can place more green plants in places with printers and copiers, which can effectively absorb carbon dioxide, release oxygen, absorb dust, etc., and improve the air quality of the office environment.
