Eye and Skin Protection:
While the Sapphire Portable Diode Laser is in use, doctors, system operators, auxiliary staff, patients, and anyone
attending them in the operatory must wear the appropriate safety eyewear that has been designed for use with
the 700-plus nm wavelengths associated with Lasers. Eye Protection must conform to Specification DIN EN207
Annex II of the Directive 89/686/EEC with optical density in 800nm-818nm of OD 4+ such as NoIR Laser
Company filter model DI1.
Nominal Ocular Hazard Distance (NOHD) is the distance from the source of laser emission to the point
where it no longer exceeds its Maximum Permissible Exposure (MPE – highest level of laser radiation to
which a person may be exposed without hazardous effects or adverse biological changes in the eyes or
skin). The Nominal Hazard Zone (NHZ) is the space within which the level of direct, reflected, or scattered
radiation during normal operation exceeds the appropriate MPEs. The outer limit of the NHZ is equal to the
NOHD. The NOHD for persons wearing recommended safety glasses is shown in Table 1 below.
Never point the Sapphire Portable Diode Laser tip directly at the face, eyes or skin of anyone while
emitting energy.
Emergency Shutdown Options:
Perform any of these actions to terminate laser emissions in the event of a real or perceived emergency:
1. Release the handpiece activation button.
2. Depress the emergency “STOP” button.
3. Remove your foot from the foot switch.
4. Turn the key counterclockwise to the “OFF” position.
5. Switch the power switch to the “OFF” (O) position.
6. Press the READY button to go to Standby mode.
