Chapter 2 Safety
All statements regarding operational safety and technical data in this manual will only apply when the unit is
operated correctly.
WARNING
Always wear appropriate laser safety eyewear during laser setup and operation.
WARNING
Use Appropriate Laser Safety Eyewear when Working with Lasers
WARNING
Visible and invisible radiation may be present.
Please note that while this is a passive device, lasers that emit high-power radiation are used in conjunction with
this device. Safe practices and proper usage of safety equipment should be taken into consideration when operating
lasers. The eye is susceptible to injury, even from very low levels of laser light. Laser emission in the visible and
near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to
those wavelengths, and the lens can focus the laser energy onto the retina. Follow all safety precautions in the
operator’s manual.
1. Never aim any laser at a person’s eye, skin, or clothes.
2. Always use proper laser safety eyewear.
3. Avoid wearing watches, jewelry, or other objects that may reflect or scatter the laser beam.
4. Keep the laser beam paths above or below eye level for both sitting and standing positions.
5. Ensure that individuals do not look directly into a laser beam.
6. Eliminate all unnecessary reflective surfaces from the vicinity of the laser beam path.
7. Ensure that all individuals who operate lasers are trained in laser safety and authorized to
operate a laser. Do not leave a running laser unattended if there is a chance that an unauthorized user
may attempt to operate the laser. A key switch should be used if untrained persons may gain access to
the laser. A warning light or buzzer should be used to indicate when the laser is operating.
8. Use low power settings, beam shutters, and laser output filters to reduce the beam power to less
hazardous levels when the full output power is not required.
9. Make sure that spectators are not exposed to hazardous conditions.
