4.4 Thermal energy
Fire, explosion
Class 3B or 4 laser light may cause fire if it ignites inflammable
material.
If there is a potentially explosive mixture of gases or aerosols
(e.g. oxyhydrogen, wood or carbon dust) in the air, a laser
beam might cause an explosion even if it does not hit solid
material with a high power density.
Do not lay hot workpieces on flammable material. Keep a hand-
held fire extinguisher readily available.
Temperature of the workpiece
Due to the processing by means of the laser beam, the work-
piece may be heated up. The degree of heating depends on the
material of the workpiece and the energy given off by the laser
beam to the workpiece during processing.
Risk of burns when touching the hot workpiece
This may result in skin injuries.
Ø Remove hot workpieces using an appropriate tool.
Ø Wear protective gloves, if necessary.
Hot surfaces on the focusing optics
Due to reflections of laser light on the workpiece, the underside
of the focusing optics may become very hot. Misadjusted or
soiled components may also cause the heating. The tempera-
ture can reach levels that may burn the skin if touched.
Hot surfaces on the bottom side of the focusing optics
may burn your skin.
Ø Avoid contact with hot surfaces.
Ø
Let the focusing optics cool down before carrying out main-
tenance or cleaning work.
