Safety Instructions On Operating The Vacuum Drying Oven - Binder vdl 23 Operating Manual

1.5.4 Safety instructions on operating the vacuum drying oven

Note the following points before starting up the oven:
• When loading the chamber and possibly at the moment of removal, also in the context of
intended use, an explosive mixture may form in the working space. Define a safety area of
at least 1m from the chamber front and ensure ventilation / venting.
• The accessible ground surface in front of the oven must be electrically conductive. This
operating area must be connected to the existing grounding concept of the vacuum drying
oven. Provide cyclic measurements.
• The operator must ensure an appropriate ventilation of the loading area in front of the oven
front prior to commissioning of the oven.
• Ensure that at no time any solvent vapors could enter in the area of the electrical installa-
tion room and the operating panel.
• Provide ventilation in the area of the vacuum pump stand, particularly in the areas of the
glass flask (when emptying it) and the exhaust air of the vacuum pump.
• The accessible area in front of the equipment must be designed conductive. Provided cy-
clic measurements.
• The personal protective equipment (PPE) of the operating personnel must be implemented
ESD protected.
Electrical hazard.
Danger of death.
∅ The oven must NOT become wet during operation or maintenance.
The inner chamber will become hot during operation.
Danger of burning.
∅ Do NOT touch the inner surfaces or the charging material during operation.
When operating the VDL vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories (formerly
BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the employers' liability insurance association)
(for Germany).
Do not start up the chamber without technical ventilation.
