While fiber laser marking machines are generally safe when used correctly, there are some potential risks that need to be considered:

l Eye Damage: Laser radiation can be harmful to the eyes, especially if protective eyewear is not worn. Exposure to laser radiation can cause temporary or permanent eye damage.

l Skin Burns: If the laser beam is not properly contained or if the operator is not wearing protective clothing, it can cause skin burns.

l Fire Hazard: Laser marking can generate heat, which can potentially ignite flammable materials if proper precautions are not taken.

l Fumes and Smoke: The marking process can produce fumes and smoke, especially when marking certain materials. These can be irritating or harmful to inhale.

l Electrical Hazards: Improper use or maintenance of the laser machine can lead to electrical hazards, such as shocks or short circuits.
