3.7.3
Hazards caused by the hydraulic system
DANGER
Risk of a high pressure injection with hydraulic oil
When working on the hydraulic system of the freeze-dryer, or due to the
ageing of the hose lines, hydraulic oil may escape.
Due to the high pressure, the oil may penetrate the skin. This may lead to
severe injuries with the risk of embolism.
• Only qualified persons are authorised to perform work on the hydraulic
system of the freeze-dryer.
• Have the hydraulic hose lines replaced at appropriate intervals
(depending on the operating conditions and under consideration of the
specifications and recommendations of the manufacturer) even if no
safety-relevant defects can be noticed!
3.7.4
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!
