Are laser cutters/engravers hazardous ? what are the safety precautions?

Laser cutter/engravers are considered to be low risk machinery if the proper safety measures are taken and respected. The laser beam generated from the laser tube can cause damage to the eye. However the beam poses no risk if the machine door is closed and the user wears safety goggles.

Additionally, users should ventilate the smoke generated by cutting or engraving with the machine. Some materials such as PVC and certain types of Kevlar produce toxic gasses and should never be used.
