2.2.2 Safe Operating Condition
If circumstances occur which impair safety and cause changes in operating behavior, the Device
should be shut down immediately and a ZEISS service representative should be informed.
The Device can only be operated after proper installation by a ZEISS service representative and in
compliance with the operating conditions. Do not operate the Device until you have completely
read and understood the entire documentation delivered with the Device. Deviating from the in-
structions given in this manual and on the safety labels can be hazardous or can lead to property
damage.
Make sure that all protective cover panels are installed and all warning labels are available and
legible. The design of the workplace must be such that electrostatic charging is prevented.
2.3 Prevention of Hazards
This section summarizes potential hazards and recommended safety precautions. Failure to follow
the safety instructions and instructions may result in personal injury and property damage.
2.3.1 Mechanical Hazards
Touch Alarm
Disabled
When the ultramicrotome is installed in the specimen chamber, the integrated touch alarm is dis-
abled.
§
Strictly follow the instructions given in this manual.
Gas Cylinders
Gas cylinders containing for example nitrogen or compressed air have a high internal pressure of
approximately 200 bar. If not properly handled, the contained gas can abruptly escape and cause
the gas cylinder to move in an uncontrollable manner.
§
Observe all safety labels on the gas cylinders and all safety instructions given by the gas cylin-
der manufacturer.
§
Always operate gas cylinders in an upright position and secure them so they will not tip over.
§
Before transporting gas cylinders, place protective caps on them.
2.3.2 Hazards generated by Materials and Substances
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.
§
To save nitrogen, it is possible to stop the nitrogen gas flow. To stop the nitrogen gas flow
click
Pump
in SmartSEM. Pumping starts automatically once the door is closed and the door
closure sensors are activated. Alternatively, turn off the vent gas at source.
§
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).
