Laser technology has become an indispensable core tool in modern industry and scientific research. However, the high energy and invisible nature of lasers also present serious potential safety risks during operation. Therefore, mastering correct laser safety knowledge and participating in systematic laser safety training are essential for every practitioner.

First and foremost, it must be understood that most lasers used in industrial and scientific research are invisible, and their beam paths are not directly perceptible to the naked eye. A seemingly safe operating environment may actually be filled with intense laser radiation. Without proper protection, the diffuse reflection of laser light from metal surfaces can cause irreversible damage to the retina. Therefore, when operating laser equipment, operators must wear laser safety glasses or masks that meet safety standards and must not look directly at the laser beam.

During operation, operators must remain alert and avoid directing the laser beam toward others. Furthermore, laser processing often generates smoke and debris. Especially when working in poorly ventilated environments, a dust mask should be worn to prevent lung damage from inhalation of smoke and dust. Also, minimize skin exposure during operation to avoid burns from hot debris or exhaust fumes.

Equipment maintenance is also a crucial aspect of safety management. Only inspect and maintain the equipment after confirming that it is not emitting laser light. Operators should develop good work habits: first turn off the power, then troubleshoot each problem one by one to avoid accidental injury from accidentally switching on the laser.

Laser safety is not just an operating procedure; it's also a sense of responsibility. Whether in a laboratory, factory, or medical setting, safe operation must be paramount. Only when every operator strictly adheres to safety training requirements and correctly uses protective equipment can this "invisible laser" truly become a powerful tool that drives technological and productivity development, rather than a hidden source of danger.
