Laser Safety
Nowadays, laser technology plays a vital role in numerous industries, including scientific research, heavy and light manufacturing, healthcare, and advanced high-tech sectors. As a result, many products equipped with laser technology have been warmly embraced by a growing number of people. According to the International Electrotechnical Commission standard (IEC 60825-1), laser products are classified into several major safety categories—Class 1, Class 1M, Class 2, Class 2M, Class 3R, Class 3B, and Class 4—based on the laser product’s wavelength, maximum output laser power, or energy.
CNI sets up control areas at locations where lasers are more likely to be marked, ensuring that appropriate warning signs remain visible. 
Symbol Usage, Safety Precautions, and Instructions
Laser hazards exist, encompassing both visible and invisible elements. Laser radiation! All safety rules and standards for lasers apply. The safety precautions and instructions mentioned in this manual do not replace the safety standards applicable in your country.

Attention: Remind operators to take precautions against hazards and ensure proper handling procedures. Incorrect operations or connections could lead to personal injury or property damage.
The laser must be turned on only after the laser enclosure has cooled down to a temperature close to its operating level, to prevent damage to the device caused by excessive thermal stress.
To extend the laser's lifespan, it is recommended not to operate outside the temperature range specified by CNI. If the system exceeds its maximum temperature limit, the protection mode will activate, and the laser will stop emitting light. Failure to follow these guidelines could result in irreversible damage to the laser. Additionally, all new industrial lasers are equipped with electrostatic discharge (ESD) protection.
We strongly recommend placing the laser on a platform with excellent heat dissipation to maintain even temperature distribution within the device. Failure to do so could result in irreversible and potentially fatal damage to the laser. Additionally, ensure that the ambient temperature remains stable, fluctuating only between 10°C and 35°C—rapid or extreme temperature changes may impair the laser's performance. Finally, avoid sticking anything beneath the laser and make sure there are no obstructions within 0.05 to 0.1 meters of the laser’s ventilation openings, guaranteeing optimal airflow and effective cooling.
Warning: Do not attempt to open, remove the laser's cover, or dismantle the laser power supply casing, as this could result in laser-related injuries and will also void the warranty. If necessary, we recommend returning the laser to Xin Industry for repair. | |
Danger, hazardous voltage! Risk of electric shock ！ |
Before operating the laser, carefully read the user manual. If you have any questions, contact the manufacturer promptly. When the laser is not in use, make sure to completely turn off the power supply. Strictly avoid allowing the laser beam—whether direct or reflected—to enter your eyes or come into contact with your body. Always wear laser safety goggles appropriate for the specific wavelength while operating the laser, and never look directly at the laser beam. Additionally, CNI offers a wide range of protective eyewear covering various wavelength ranges. Below are key precautions to keep in mind when using the laser.
- Never observe laser light or scattered laser radiation, either directly or indirectly.
- When the laser level is below Class I, it should still be observed using a display screen—never directly with the naked eye.
- Wear appropriate safety goggles—while goggles are designed to protect your eyes, make sure not to look directly at laser beams or highly reflective surfaces when wearing them.
- Laser exposure on highly reflective surfaces—such as mirrors, glass, and metal objects—can cause serious injury. Additionally, scattered laser light resulting from reflection also poses significant hazards.
- Make sure not to point the laser randomly at targets.
- Do not use lasers in areas marked "No Smoking" or "Flammable and Explosive," as this could easily lead to dangerous situations.
- For invisible lasers, before using the laser device, check whether the laser is functioning by employing an infrared detector or an infrared display card.
- When dealing with optical issues, use clean finger cots, latex gloves, or other insulating equipment.
- Post warning signs in a prominent location within the laser operation area, set up reminder markers when the laser is in use, and restrict access to non-operational personnel in the laser work zone.
- If the laser is not in use or unattended, it should be completely turned off.
- To avoid accidentally staring directly at the laser spot, make sure the laser is positioned well above eye level.
- When the equipment is no longer in use, immediately disconnect the main power cord and ensure the laser head remains securely connected to the power supply with the same serial number to prevent static damage.
- Any operation involving disconnecting or reconnecting the laser head from the laser power supply must be performed with the power completely turned off.
- If conditions permit, keep your distance from the equipment to reduce the risk of electric shock.
- After the power is turned on, do not touch exposed wires and components.
- When maintaining or repairing electrical equipment, be sure to use insulated tools.
- To prevent damage to the laser system caused by lightning strikes, static electricity, electrical interference, and other similar factors, it is essential to ensure proper grounding of the laser system.
- To prevent fire or electric shock, please follow all ratings specified on the product and its instruction manual. Before connecting the product, be sure to consult the user guide first for detailed information about the ratings.
