Laser Safety

This unit is a Class IV laser, which means that both the laser beam as such and the diffuse
laser light reflected from surfaces may be harmful.
The unit emits radiation in the non-visible spectral range of 10,600 nm. Such
radiation can cause irreversible damage to the eyes, skin and other organs!
The laser area is defined as the area in which the maximum permissible exposure (MPE) values
that are normally binding may be exceeded. This includes any accidental deflections of the
laser beam. All doors providing access to the laser area must be marked with warning lamps.
Therefore, the following safety measures must be strictly observed:
Any person present in the laser area while the laser is being used must be aware of the
dangers posed by laser radiation and must wear protective goggles. The patient's eyes
must be adequately protected as well.
The owner/operator of the unit is responsible for providing suitable protective equipment.
The organ most endangered by laser radiation is the human eye. Therefore, all persons
present in the laser area must wear protective goggles (rated 10,600 nm L4 or higher)
whenever the unit is switched from "standby" to "laser ready" mode.
Use protective goggles – D 10,600 nm L4 – in accordance with DIN EN 207
requirements!
Never stare directly into the red pilot laser light! Please note that the protective goggles
just mentioned do not protect against the red pilot laser radiation!
When performing open surgery, the entire operating room is considered the laser area.
Never keep potentially explosive substances in the laser area, as easily flammable
materials could catch fire!
If laser radiation is applied to organs, body cavities or tubular structures in which easily
flammable gases or vapors may be present, protective measures must be taken to
eliminate any fire and explosion hazards.
Objects capable of reflecting the CO
altogether from the laser area. Windows and reflecting walls should also be covered with
suitable materials. Moreover, adequate protective measures must be taken if harmful
gases, dust, smoke or secondary radiation could be generated, or if potentially explosive
gas mixtures could be formed, as a result of the impact of laser radiation on certain
substances or materials.
Instruments that need to be brought into the beam path in the course of the treatment
must have such a shape and finish that dangerous reflections are largely excluded.

radiation must either be covered or removed
