2 Safety | 2.3 Prevention of Hazards
Risk of property
damage: Short
working distance
When opening the chamber door, the microscope or specimen can be damaged if the specimen
stage is at a short working distance. If a BSD detector is inserted, it can be damaged as well.
§
Always move the specimen stage to a long working distance before opening the chamber
door.
2.3.8 Radiation Hazards
Danger to life: X-
rays
X-rays are generated inside the microscope during operation. This is unavoidable because elec-
trons are accelerated by voltages up to 30 kV.
§
Do not remove any parts around the column and chamber that are essential for radiation pro-
tection.
§
Use genuine ZEISS parts exclusively.
§
Ensure that all local safety and X-ray protection regulations are met.
§
Only authorized ZEISS service representatives are allowed to service the microscope.
The microscope is equipped with several radiation protection devices, which, under regular oper-
ating conditions, ensure that the microscope operates in accordance with the German X-ray pro-
tection regulation (RöV), the German radiation protection regulation (StrSchV) as well as with the
EC Directive 2013/59/EURATOM.
In the EU, the operation of the microscope is permission-free as the following requirements are
fulfilled:
§
The acceleration voltage is limited to 30 kV.
§
The local dose rate at a distance of 0.1 m from the accessible surface of the microscope does
not exceed 1 μSv/h.
§
A respective label is attached to the microscope.
Outside the EU, the user of the microscope has to comply with the local regulations of the coun-
try where the microscope is operated.

2.3.9 Suffocation Hazards
Danger to life:
Lack of oxygen
Gaseous dry nitrogen is used to vent the specimen chamber during specimen exchange and parts
exchange. Inhaling nitrogen may cause unconsciousness.
§
During specimen exchange, keep the chamber door open as short as possible.
§
Do not inhale the air from within the specimen chamber.
§
Ensure that the area around the microscope is sufficiently ventilated.
§
If you begin to experience symptoms of asphyxia (for example: rapid breathing, loss of mental
alertness and/or muscular coordination, depression of sensations, emotional instability, fa-
tigue) leave the room immediately and inform the facility’s safety officer.
Concerning the hazards of nitrogen installations and associated safety precautions refer to the
current version of the guideline IGC Doc 44/18: Hazards of Oxygen-Deficient Atmospheres, pub-
lished by EIGA (European Industrial Gases Association).
