Zagrożenia elektryczne

Many laser systems inclusivate high- voltage power sumlies, condentials, and pulsed objectes that pose letal shock risks. Even after diconnecting power, condentiors can retail in charge for minutes or hours. Lockout / tagout procedures must be exempled during confidence. In addition, coloing systems (water chilers) and auxiliary actomics present slip, trip, and electrical shock hazards.

Chemical andd Airborne Contaminats

Laser- material interaction can generate hazardoos fumes, gases, and suclelates. Cutting plastics, metals, or composites produces toxic byproducts such as dioxins, hevy metal duss, and contexle organic compounds (VOC). These contaminants pose inhalation risks and may accumulate in contect filters. Local extrat vention (LEV) and proper filtration systems are essential.
