1.2 WARNINGS AND CAUTIONS ON EXPOSURE
WARNING
1 It is extremely dangerous to expose your eyes to direct,
scattered, or reflected CO
2
laser light. Always wear
protective glasses while the laser is operating.
Exposure to laser light can cause blindness. If your eyes
are accidentally exposed, seek medical advice
immediately.
2 Do not turn on the laser oscillator while a panel is removed
or a door is open.
Operating the laser with a door open or panel removed
may result in the operator being directly exposed to CO
2
laser radiation. Exposure to laser light can cause blindness
and/or severe burns. If your eyes are accidentally exposed
to laser light, seek medical advice immediately.
Before turning on the power during maintenance if
absolutely necessary, wear protective glasses and clothing
to prevent accidents.
3 Surround the laser-machining tool with a fence made of a
material which absorbs laser light well (such as acrylic).
Place appropriate warning notices on the fence.
The door in the safety fence shall be fitted with an interlock
switch such that opening the door stops the laser.
Failure to provide such a fence exposes persons in the
vicinity of the machine tool to the danger of being exposed
to CO
2
laser radiation and the associated risk of blindness.
If a person is accidentally exposed to laser light, seek
medical advice immediately.
4 If the laser oscillator is operated with a panel open,
ultraviolet radiation is emitted from the high-frequency
discharge section. Gazing the discharge section for a long
time can cause visual disturbances such as impaired
eyesight.
Always wear protective glasses during work. If you feel
trouble with your eyes, seek medical advice immediately.
5 The laser beam shall be no higher than average eye
height. Enclose the path of the laser beam with covers. Do
not leave the end of the beam path open. Place laser-
absorbing material at the end of the beam path to absorb
the beam's energy.
A CO
2
laser beam is directional and has a high energy
density. Exposure to laser light can cause blindness.
Flammable material may burn or explode if exposed to the
laser beam. If your eyes are accidentally exposed to laser
light, seek medical advice immediately.
