High power laser equipment are increasingly being used for welding, cutting and surface treatment in metal industry. The most common types of lasers for material processing purposes are Nd:YAG-and CO2-lasers. Usually they are open-beam systems belonging to the Safety Class 4. The aim of this study was to evaluate the hazards of optical radiation from these infrared lasers in industrial applications.
