If used properly, the LSM 710 and LSM 780 systems and ConfoCor 3 will not pose any laser radiation
risks for operating staff. Nevertheless, you should observe the following warnings:
•
If necessary - insofar as specified by law - inform the laser safety officer before
commissioning the laser.
•
The LSM system and the Ar laser are equipped with a key-interlock.
•
Always store keys for laser key switches and, if applicable, keys for further laser power
supply units, where they are inaccessible to persons not authorized to operate the laser.
•
A laser ON LED on the scan head lights up when laser radiation is emitted.
•
Do not place any reflecting objects into the beam path.
•
Never open any covers or panels.
•
Never look into the laser beam, not even to simply view the specimen, whether with the aid
of optical instruments or without. Otherwise you risk going blind!
•
Do not leave any empty objective positions of the nosepiece uncovered.
•
If a class 4 laser is attached to the system, already stray light can impose danger to the
operator.
•
With class 4 lasers take special care of fire protection requirements. Do not use or store
flammable or explosive solids, fluids or gases in the vicinity of the system.
•
Class 4 lasers can inflame also flammable materials like cloth or paper. Do not put such
materials into the beam path.
•
Do not reach into the process beam inside the sample area whenever the Class 4 laser is
active!
Suitable protective measures must be taken if gases, dust or vapors hazardous to health, secondary
radiation or explosive objects should arise on the specimen as a result of laser radiation.
