This information intended for the educational, instructional, and informational purposes of the user. It is not to be considered a substitute for a knowledgeable and trained Laser Safety Officer (LSO) with the duties and responsibilities as defined in the ANSI Z136 standard published by the American National Standard Institute.
Please use the information as a general guide.
Class 4 (IV) lasers are hazardous to the eye. They can also burn skin and materials, mostly dark and/or lightweight materials, at close range. They should be used with extreme care.
Class 4 lasers have an output power of 500 milliwatts and above for visible-light lasers. There is no upper limit for Class 4, which is the most hazardous laser classification.
Avoid exposure to skin and sensitive materials. A Class IV laser can burn skin and materials, primarily Hello dark and/or lightweight materials at close range.
Class IV visible-beam lasers are high-powered. A Class IV laser can cause a significant eye injury if the direct or reflected beam enters the eye.
Even staring at the diffuse reflection of a laser “dot” on a wall or other surface may cause an eye injury within a few feet of the dot. Do not stare at the laser “dot” when it is close to you.
To prevent eye exposure, always be aware of the beam location. Please keep it away from people’s eyes and heads. Watch out for reflected beams from glass and shiny surfaces.
Use of laser protective eyewear is mandatory
The fiber laser cutter is enclosed with a safety interlock and shuttle tables for materials (in and out)
The operator must wear safety goggles. The machine needs to be secure with partitions or in a separate room.
The operator must wear safety glasses to protect exposed skin, Gloves, and arm and neck protection (the same as regular welding). The laser should be in a separate room. Or protected with special dividers
One of the most critical risk factors, especially for operators, comes from the radiation emitted during welding. The most dangerous type is ultraviolet radiation, absorbed almost entirely by the skin and eyes. However, using infrared lasers results in minimal UV light generation and a reduced risk of UV damage. Therefore, protecting each exposed area is the most effective solution. Infrared light radiation is much less dangerous.
Welding fumes, on the other hand, present a very different problem. The effects vary depending on the type of metal being welded, ranging from respiratory issues to damage to the skeletal system. For this reason, the work area must be well-ventilated or equipped with appropriate suction machinery during welding.
Another element that requires suction is welding dust, which consists of tiny, highly toxic particles capable of penetrating the respiratory system. Electrode welding generates the highest concentration of dust among all welding techniques, so wearing a mask for protection is essential.

When buying laser safety glasses and goggles, select glasses that block or attenuate the appropriate wavelength range (1080nm) and Optical Density (6 or 7 OD).
Everybody exposed to a Class 4 laser beam must wear appropriate safety glasses. These glasses must meet two variables:
Every laser beam has a specific wavelength or color. Therefore, manufacturers make glasses of glass and polycarbonate to protect against different wavelength ranges.
The other variable is Optical Density. This is how to measure the radiation the glasses permit to pass through the lenses. OD is the base-0 logarithm of the factor by which the glasses or other filter reduces the power of the laser beam. For example, an OD of 4 reduces the laser beam’s power by 10,000, a factor of 4, because 1,000 is 10 to the power of 4.
This helmet features a laser protection window made of a dark green absorbing plastic on a PMMA basis that is particularly resistant to lasers. The window provides laser protection by absorbing the laser radiation within the material itself. With a daylight transmission of approximately 64%, the window offers adequate visual brightness and color visibility. It is certified according to DIN – EN 60825-4 and CE, ensuring safe use in machines or shielding even with large beam diameters.
To ensure proper laser safety, it is important to calculate the required protection levels for your laser and compare them with the specifications on the laser protection window before installation.
Please note that this helmet is not designed for direct exposure to all laser beams. It is advisable to consult with your laser protection officer regarding compatibility.

This protection helmet features a laser protection window made of a dark green absorbing plastic, which is particularly resistant to lasers due to its PMMA composition. The laser protection is achieved through the material’s ability to absorb laser radiation. The window allows approximately 68% of daylight transmission, providing adequate visual brightness and color visibility. It is certified according to DIN – EN 60825-4 and CE, ensuring safe use in machines or shielding even with large beam diameters.
To ensure sufficient laser safety, please calculate the required protection levels for your laser and compare them with the specifications of the laser protection window before installation.
It is important to note that this helmet is unsuitable for direct exposure to all laser beams. Please consult with your laser protection officer to verify compatibility.
