Laser radiation hazards

2.6
Never direct the laser or aiming beam toward a person's eye! All
persons present in the room e.g. patient, dentist and assistant must
always wear the laser protective goggles.
Observe all labels on the SIROLaser Xtend.
Note that after switching off the master switch of the practice the
SIROLaser Xtend will still remain switched on. It is then energized by
the rechargeable battery.
In case of an emergency press the "Laser Stop" button below the touch
screen on the front side of the SIROLaser Xtend control unit.
Failure to use the settings specified in this manual or perform the
actions described here may lead to a dangerous exposure to radiation.
Sirona Dental Systems GmbH cannot be held liable for any damage
caused by improper use or non-compliance with the instructions and
information provided in this manual.
Never direct the laser beam towards any flammable material, e.g. paper
or plastics. They could catch fire due to the high temperatures produced
by the laser beam.
The unit is not suitable for use in the presence of anesthetics that are
flammable when in contact with air, oxygen or nitrogen monoxide.
Oxygen-saturated materials such as cotton wool can catch fire owing to
the high temperature that the unit reaches during operation. Label
removers and flammable solutions used for cleaning and disinfecting
the SIROLaser Xtend should be allowed to evaporate before using the
device. Observe fire hazards caused by flammable gases.
If any tissue is unintentionally irradiate, this may lead to burns. This risk
can be reduced by surrounding the target area with moistened sterile
drapes or gauze doused in salt. These covering materials must meet
the requirements of laser surgery.
An extractor or a filter should be used. The operating personnel should
be aware that biologically active material could get into the enviroment.
It may contain particles of viable tissue.
