Hand-held laser processing machines (HLM): legal considerations for the European Union on this controversial innovation

Hand-held Laser processing Machines (HLM) for welding or cleaning require laser energies that correspond to the most dangerous laser class four and are therefore far above the exposure values for the eyes and skin. Irradiation of the unprotected eyes by the scattered radiation reflected by the workpiece leads to irreparable eye damage (blindness)! Incorrect irradiation of the hands, for example, by the direct beam leads to severe burns! Unfortunately, the majority of products currently on the market in the European Union do not comply with the relevant manufacturing laws. Failure to comply with the law means that such products or work equipment are not legally permitted in the European Union and personal injuries that occurs will likely result in legal proceedings. Efforts are being made to make hand-held laser processing machines safer by means of safety devices on the laser applicators and also by integrating laser safety visors into the safety circuit, but these efforts are not yet sufficient in terms of the hazards to be prevented. This article is intended to help international manufacturers of hand-held laser processing machines understand the legal requirements and place their products more successfully on the European market.
