Hazards caused by nitrogen
DANGER
Risk of suffocation caused by nitrogen
If the chamber is aerated with nitrogen, the gas may escape through
openings in the system (e.g. supply lines that are not properly connected
or a loading door that is not closed correctly).
There is a risk of suffocation in the case of high concentration levels.
Possible symptoms are paralysis and unconsciousness. Affected persons
do not notice the fact that they suffocate.
• Use the freeze-dryer only if it is equipped with pipes that are properly
connected!
• Only qualified persons are authorised to perform work on the nitrogen
lines of the freeze-dryer!
