1) Develop and strictly adhere to equipment operating procedures.
2) Before starting the machine, check the safety facilities of the system, especially the switch of the blinds.
3) Maintain the machine in a timely manner.
1. Fire extinguishing equipment must be equipped on site
The laser cutting machine should be equipped with fire extinguishers and other fire-fighting equipment. Operators should understand the layout and usage methods.
2. Manage the location of the laser cutting machine as a hazardous area
The area where the equipment is located should be designated as a hazardous area and enclosed with a retractable isolation tape. Leakage outside the laser hazardous area should be maintained within the following achievable emission limits.
Warning signs should be set up at the entrance and exit of hazardous areas, including invisible laser radiation, laser cutting machine power supply, prohibiting outsiders from entering, and paying attention to eye protection
When the laser cutting machine is working, it is strictly prohibited for anyone to approach the dangerous area.
3. It is strictly prohibited to work after being tired and drinking alcohol.
The use of laser cutting machines and other laser processing equipment poses significant risks. If negligent, it is likely to cause harm. Therefore, it is strictly prohibited to operate the laser cutting machine after working hard and drinking alcohol.
Do not look directly at the laser beam
4. It is strictly prohibited to open the machine cover during the operation of the laser.
During the operation of the laser, it is strictly prohibited to open the upper cover of the laser.
Closed fiber laser cutting machine, it is strictly prohibited to open the protective door during the entire operation process.
5. It is strictly prohibited to wear metal items for maintenance operations.
Those without maintenance qualifications are strictly prohibited from repairing or adjusting the laser.
When repairing or adjusting the laser, it is strictly prohibited to wear metal accessories or items (such as rings, bracelets, watches, earrings, metal belt buckles, etc.). Otherwise, it may cause electric shock.
The maintenance and adjustment of lasers and photoconductive systems is an extremely dangerous task. To prevent accidents from occurring, it is prohibited to carry out maintenance work alone and “two people walking together”.
6. It is strictly prohibited to output the laser beam when there is no target material.
It is strictly prohibited to output the laser beam when there is no target material. Otherwise, the laser beam will directly irradiate the equipment, causing equipment and personal accidents.
7. It is strictly prohibited to stack flammable materials in the processing area of the laser cutting machine.
It is strictly prohibited to stack flammable materials such as paper, oilcloth, and oil near the laser cutting machine.
When using oxygen as a cutting auxiliary gas, there should be no oil stains on the surface of the material. Otherwise, it can easily cause a fire.
8. Do not enter hazardous areas while the machine is working
The danger zone of the laser cutting machine is the entire workbench, and if it is an open workbench, it extends outward. The processing area is the main hazardous area. In this area, moving the beam of light may have an impact on the human body; The movable beam and fixed bed, door, and base may compress the human body; Sharp objects or needle like support pins may puncture or pierce the human body; High power and high-density lasers may cause fatal harm to the human body.
9. Maintain ventilation, cleanliness, and sufficient lighting in the work area
The working area of the laser cutting machine should ensure good ventilation to facilitate the discharge of harmful gases (such as pipeline bursting due to nitrogen overflow or cylinder leakage). Ensure that harmful gases and substances during the processing, as well as laser working gases, are completely discharged to the outside.
Gas cylinders should be placed on the cylinder rack, as close as possible to the wall, stable and tidy.
In the laser safety management area, good lighting should be ensured.
10. Wear goggles and protective clothing
Operators of laser cutting machines or those who approach the laser during use should wear appropriate protective glasses (with side shields corresponding to the laser wavelength) as much as possible. The purpose of wearing goggles is to avoid eye exposure to possible laser radiation, metal splashes generated during cutting, debris generated by lens bursts, and damage caused by high-pressure pipeline bursts.
11. Key management
When the operator leaves the laser cutting machine, they should remove the switch key of the equipment and the laser key to control the power supply to prevent accidental operation by other personnel.
12. Properly handle damaged optical components
Focusing mirrors, reflectors, and their coatings can form toxic substances when overheated or otherwise damaged. When handling, wear latex gloves and do not touch with bare hands. Damaged lenses cannot be treated as regular waste and should be disposed of by a professional organization.
