1 Safety Precautions
• Read and understand the instruction manual of the particular type of
laser. Take special care with respect to laser emission, high voltage
and hazardous gases if in use.
• Declare a controlled access area for laser operation. Limit access to
trained people. Never operate the laser in a room where laser light
can escape through windows or doors. If possible, cover beam paths
to avoid obstacles getting into the beam.
• Provide adequate and proper laser safety-goggles to all persons
present who may be exposed to laser light. The selection of the gog-
gles depends on the energy and the wavelength of the laser beam
as well as the operation conditions. Check the Laser´s manual for a
detailed description.
• While working with lasers do not wear reflective jewelry like watches
and rings, as these might cause accidental hazardous reflections.
• Avoid looking at the output beam, even diffuse reflections can be dan-
gerous.
• Operate the laser at the lowest beam intensity possible.
• Avoid blocking the output beam or reflections with any part of the
body. Use beam dumps to avoid reflections from the target.
• Wear clothes and gloves which cover arms and hands to avoid skin
damage when handling in the optical path. Especially UV-radiation
can cause skin cancer.
1.2 Seizures Warning
WARNING: HEALTH HAZARD! STROBE LIGHTING COULD TRIGGER SEIZURES
Some people (about 1 in 4000) may have seizures or blackouts triggered
by flashing lights or patterns. This may occur when viewing stroboscopic
lights or objects illuminated by such devices, even if a seizure has never
been previously experienced. Anyone who has had a seizure, loss of aware-
ness, or other symptoms linked to an epileptic condition should consult a
doctor before operating systems which include flashing lights, strobe lights,
or a pulsed or modulated laser.
Stop operating the system immediately and consult a doctor if you have
one of the following symptoms:
