3.6.5 Chemical and biological safety
If infectious, toxic, pathogenic, or radioactive substances are intended to be
dried, it is in the responsibility of the user to ensure that all necessary
safety regulations, guidelines, precautions, and practices are adhered to
accordingly.
DANGER
• Infectious, toxic, pathogenic, and radioactive substances must be dried
in suitable accessories. Take suitable precautions for your own safety!
• Do not dry products with a high solvent concentration or acidic
products without special protective measures or device-based
precautions (e.g. an additional cooling trap to protect the vacuum
pump). It is absolutely necessary to consult the manufacturer in these
cases (see chapter 7.3 - "Service contact").
• Special caution is necessary when handling azides, as a dangerous
explosive develops in combination with copper or nonferrous metals! It
is absolutely necessary to contact the manufacturer (see chapter 7.3 -
"Service contact").
WARNING
• Keep informed about local measures to avoid harmful emissions
(depending on the substances to be dried).
• As personal protective equipment, safety gloves are required for the
use of the freeze-dryer.
The materials to be dried may, however, require additional special
safety measures (e.g. drying of infectious, toxic, radioactive, or
pathogenic substances)

3.7.1 System check
An internal system check system monitors the data transfer and sensor
signals with regard to plausibility. Errors are detected by continuous self-
monitoring of the system. Error messages are displayed in the main
window under "Process & equipment messages" (chapter 6.5.1.1 - "Main
window "Manual"", chapter 7.2 - "Process and error messages").
