EXCEL V+ OPERATOR MANUAL
D2325, REV A, 2/19
All personnel operating excel V+ or in the vicinity of the system, including the patient, staff personnel and
observers, should wear protective eyewear with sufficient protection (optical density or shade factor
specified in
System Specifications or greater) for the 532 nm and 1064 nm wavelengths. The eyewear
should have guards on both sides to protect the eyes from lateral exposure.
Guidelines and information on the safe use of lasers, and the safe use of lasers/laser systems in
diagnostic and therapeutic areas, can be found in the following:
• The American National Standard for the Safe Use of lasers in Health Care Facilities (ANSI
Z136.3)
.
• The American National Standard for Safe Use of Lasers
(ANSI Z136.1) .
• European Standard EN 60825:2014, Annex A.
The ANSI and the European standards describe the following terms in the description of laser hazards:
• Maximum Permissible Exposure (MPE) - The highest level of laser radiation to which a
person may be exposed without hazardous effect or adverse biological changes in the eye
or skin.
• Nominal Ocular Hazard Distance (NOHD) - The distance along the axis of the
unobstructed beam beyond which exposure during normal operation is not expected to
exceed the appropriate MPE. This distance is measured from the laser aperture.
• Nominal Hazard Zone (NHZ) - The space within which the exposure level during normal
operation exceeds the applicable MPE. The outer limit of the NHZ is the NOHD.
For specific values, see Eye Safety in the System Specifications section of this manual.
In addition to providing the required laser safety eyewear, take the following steps to secure the
treatment room or controlled treatment area:
1. To alert personnel before they enter the controlled area, place a warning sign on the
outside of the treatment room door when the laser is in use.
WARNING
The excel V+ produces visible green (532 nm) light, as well as
invisible (1064 nm) light, both of which can cause permanent eye
damage. Never look directly into the handpiece even when wearing
protective eyewear. Never look directly into the laser beam or at
scattered light from metallic or other reflective surfaces. Both direct
and reflected laser beams may contain sufficient energy to cause
permanent eye damage.
WARNING
Never allow anyone without proper protective eyewear near the
laser while the system is in use.
