2.7.1
Fire hazard
Warning
Fire hazard
Fire hazard from gas and processing of inflammable materials.
–
Do not operate the device without supervision.
–
Keep CO
If a main laser beam hits easily flammable material, e.g. paper, this may ignite and a fire can quickly occur. Therefore,
before switching on the laser, you should make absolutely sure that there is no easily flammable material in the beam
path.
Furthermore, gases that can form below the material to be processed may ignite. Especially if the extraction
requirements are not met.
Inadequate care and cleaning of the system increases the risk of flame formation.
Regularly check the cooling slots of the cooling system.
2.7.2
Gases, fumes and dust
Depending on the materials being processed and the parameters selected, laser processing may generate gases, fumes,
aerosols or dust. Depending on the material, such by-products may be toxic. In individual cases, the reaction products
may be electrically conductive dusts. If these enter electric systems, short-circuiting with personal injury and property
damage may occur.
The operator is responsible for ensuring presence of a suitable extraction system and compliance with the relevant
guidelines in order to protect persons and the environment. Find out about local guidelines.
The operator must also ensure that gases, fumes or dust do not settle on the processing lens. Any dirt accumulating on
the processing lens can lead to loss of performance, poor processing results and damage to the device.
