    Laser safety 4. Potential hazards related to materials worked with „ Fumes and toxic particles Laser marking certain materials emits dangerous fumes and particles that may be toxic and/or damage the equipment. In this case, adapt an extraction system (with filtration if necessary) to the marking station. The processing of parts using this type of Laser causes thermal and photo-electric (molecular) deterioration of the material. Even micro-quantities of the by-product (soot or fumes), created during Laser marking, may accumulate over a long period.
