fire extinguisher ready at hand in the immediate vicinity of the device.
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 your air cooling system on the laser. The function of the filters and fans in particular should
be checked regularly so that defects caused by excess temperature are avoided.
2.8.2 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. The guideline VDI 2262 1-3 "Workplace
air" provides, among other things, additional remarks.
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.
