Always use the laser engraving and cutting machine in a well-ventilated area. The machine uses a laser beam to rapidly heat, melt and partially or completely vaporize the material, creating gases and particulate matter. These byproducts of laser operation may irritate the eyes and respiratory system. Never use the laser engraving and cutting machine in an enclosed area that doesn’t have good ventilation. Otherwise, serious personal injury may occur.
We recommend that you use ventilation devices such as fans to exhaust the gases and fumes produced to the outdoors. You can also use an air purifier to freshen the air. If you do not have ventilation or filtration equipment, ensure that your workplace is well-ventilated. Open doors and windows to allow air to flow.
2.1.2 Fire Safety
Never operate the laser engraving and cutting machine near flammable or explosive substances. The machine uses a high-intensity beam of light that can result in a large amount of heat. Flammable or explosive substances exposed to direct or reflected laser beams pose a fire hazard. Besides, the materials being engraved or cut may be ignited and burst into open flame. This open flame is very dangerous and has the potential to destroy not only the machine but the building in which it is housed.
Install a smoke detector in your workplace. Always keep a properly maintained and inspected fire extinguisher on hand. Typically, Carbon Dioxide (CO2) chemical fire extinguishers should be used. Always have a first-aid kit designed for the initial treatment of burns and smoke inhalation nearby. Ensure that this kit is put in an area that is outside risk areas.
2.1.3 Humidity and Temperature
The ambient humidity should be kept between 30%–70%. Do not use the laser engraving and cutting machine in wet surroundings. Water entering the machine may increase the risk of an electric shock. Ensure your workspace is dry and not subject to potential wet conditions.
The ambient temperature should be kept between 0°C–40°C (32°F–104°F). If the temperature is higher than 40°C, the heat generated by the laser engraving and cutting machine cannot be properly dissipated, and thus may cause damage to the machine. If the temperature is lower than 0°C, some electronic components cannot work properly.
2.1.4 Clean and Bright Space
Keep the work area clear and well lit. Cluttered or dark areas invite accidents. Clean around the machine and keep the area free of clutter and combustible materials. Provide at least 8 inches of unobstructed spacing around the laser engraving and cutting machine to allow ventilation. Stacking materials (especially organic materials such as paper) can lead to an increased risk of flame propagation or workpiece ignition.
Put the laser engraving and cutting machine on a sound and level workbench.
Put the laser engraving and cutting machine in a well-ventilated place during laser engraving and cutting.
Put the workbench near ventilation openings should you use the laser engraving and cutting machine with an enclosure or purifier.
Keep the workbench clean and dry.
