Class 4 lasers can induce severe eye and skin injuries due to direct or scattered light when used without the correct protective measures such as eyewear and clothing. In addition to this, these lasers also pose a fire hazard when used incorrectly or with the wrong type of materials. Due to the risks associated with Class 4 lasers, it is necessary to have the appropriate laser expertise or certification before operating a Class 4 laser cutter.
Some guidance on what to look out for:
- Never leave the laser cutter unattended and keep a fire extinguisher in the same room as the laser cutter. Even when your laser cutter has a fire extinguisher built-in, you still need this precaution to be taken.
- Use the laser cutter as intended / described in the user manual included to ensure safe operation and avoid any hazards.
- Always use laser eyewear that corresponds to the correct wavelength range of the laser cutter you are using:
- CO₂ laser wavelength: 10.6 µm
- Blue diode laser wavelength: 445 nm
- Infrared diode laser wavelength: 1064 nm
- Always wear clothes to cover your skin to avoid direct exposure as this can lead to severe injuries and long-term damage.
- Always keep the work area clean after each project by removing all residue left behind by said project to reduce any fire hazards.
- Make sure you read through all safety and operating instructions included in the user manual before using the laser cutter.
