1. The equipment should be grounded reliably, the maintenance door should be equipped with interlocking devices, and the capacitor bank should have discharge measures.



2. Apparent danger warning signs and signals should be installed on the processing equipment, such as laser danger, high pressure danger and so on.



3. The optical system of laser should be closed as far as possible. For example, laser should be transmitted in metal tube to prevent direct exposure to human body.



4. If the laser path cannot be completely closed, the optical path should be set at a higher position so that the beam can pass from a higher position to avoid the human head.



5. Glass and other protective devices should be used in laser processing workbench to prevent reflecting light.



6. Laser processing sites should also be equipped with safety signs and barriers, partitions and screens to prevent irrelevant personnel from entering dangerous areas.
