Regularly check the function and the operation safety of the
exhauster and ensure a sufficient ventilation in the room.
When recirculating the exhausted air into the room, ensure that
the rest quantities of harmful substances are below the admissi-
ble limit values.
Inform persons staying in the room on risks and instruct them in
danger-conscious behavior.
4.3 Thermal energy
Fire, explosion
Class 3B or 4 laser light may cause fires 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.
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 values that may burn the skin in case of a con-
tact.
