Abstract

Lasers are now indispensable tools in industry, medicine, communications, and scientific research. Their precision and efficiency have led to widespread adoption. However, their use demands significant caution, as laser radiation poses a serious hazard to the human body, especially the eyes and skin. Due to this reason, most laser sources are isolated from the environment (protective enclosure), however, there are applications where the operator is in the same airspace as the equipment emitting hazardous radiation. In an industrial environment, cutting, welding, and cleaning tasks can be performed with manual laser equipment. In this case, not only does the laser radiation pose a potential risk, but also the smoke gases and aerosols generated during the interaction between the laser light and the material, which can lead to respiratory diseases. To ensure safe operation, the proper use of protective equipment – such as laser safety goggles and specialized clothing – is crucial, along with meticulous workspace design and adherence to international standards. En suring radiation safety is not only essential for protecting individual health, but also a fundamental require ment for the sustainable and safe application of laser technology.
