Chemical safety

Some materials may release toxic and harmful dust, smoke or gases after laser processing. Therefore, precautions are required for chemical safety during material processing.

Follow the safety precautions:

• Before processing, evaluate whether the material will release substances harmful to human health, air purifiers, the environment, or the equipment itself. Never process any unknown materials or materials incompatible with laser processing.
• Users are responsible for implementing appropriate protective measures based on the material to be processed. These measures include, but are not limited to: ensuring proper ventilation of the workplace, using suitable air purifiers, and wearing personal protective equipment (PPE). Users are also responsible for ensuring compliance with local regulations regarding limits on dust, fumes, and gas emissions.
• Exercise caution when you process materials that contain PVC, vinyl, ABS, polycarbonate, or substances such as chlorine, benzene, ammonia, fluorine, phenol, and aldehydes. When being processed by laser, these materials can generate dust, smoke, or gases toxic and harmful to human and corrosive vapor that may damage the product. Do not process them without adequate protection. Necessary protective measures include: ensuring proper ventilation of the workplace, using suitable air purifiers, and wearing PPE.
