The laser machine is equipped with a sealed carbon dioxide (CO2) laser that can emit strong and invisible laser radiation with a wavelength of 10.6 microns (10600 nanometers) in the infrared spectrum. Due to the applicable wavelength, lightning laser radiation is invisible to the human eye.
Infrared (invisible) laser radiation is particularly dangerous to the human eye, as its enhanced effect through the lens is concentrated on the retina of the eye. High intensity radiation on the retina can cause strong local heating and burn its tissues, leading to decreased or lost vision. Therefore, when working near the laser beam (during maintenance, optical system positioning, repairs), always protect your eyes.
The laser equipment kit includes goggles for handling materials that can reflect laser beams. Users must wear safety goggles to operate the machine. Goggles cannot protect the eyes from direct laser beam damage, and can only be protected from reflection for a few seconds.
Avoid laser and red beams entering the eyes directly. During continuous visual observation, the reflection of the laser beam may cause glare. Do not look directly at the reflected beam on the metal of the speculum. Do not look directly or diagonally at the aperture of the laser and red beam.
Users are responsible for adhering to health and safety when operating the laser machine.
When operating the machine, direct, reflected, and scattered laser radiation is dangerous. Prevent hand and body contact with the laser beam work area. Scattered laser radiation can burn the skin on the hands. The degree of damage depends on the duration of laser beam irradiation. Appropriate protective clothing must be worn to protect the skin.
The smoke, toxic gases, and particles released during laser operation can seriously damage your health and lead to death. Carefully check the material Safety data sheet (MSDS) and the material composition of hazardous substance emissions. Provide high-quality air extraction system in the working area of the laser engraving machine. The smoke and gases emitted during the cutting and carving process can contaminate and damage the optical lens and reflector.
The focusing lens of the laser machine is made of Zinc selenide (ZnSe). Focusing lenses are safe for health under normal operating conditions, but they require regular inspection and cleaning. If damage occurs (cracks, cracks, scratches, wear, overheating, etc.), a new focusing lens must be replaced. The use of damaged optical components can cause toxic gas emissions and harm your health.
When using a damaged focusing lens, toxic vapors of zinc oxide and selenium oxide can be emitted. Zinc selenide is toxic if inhaled or swallowed. Dust may irritate the eyes and respiratory system. If you find damage to the optical components, you must thoroughly ventilate the room and carefully clean the dust on the laser equipment, which is formed by the discharge of toxic vapors on the damaged optical components. Please contact your supplier for more detailed information on laser safety.
