2 Safety
This chapter points out the safety concept of the instrument and contains general rules of behavior
and warnings from hazards concerning the use of the product.
The safety of users and personnel can only be ensured if these safety instructions and the safetyrelated warnings in the individual chapters are strictly observed and followed. Therefore, the manual
must always be available to all persons performing the tasks described herein.
2.1 User qualification
The instrument may only be used by laboratory personnel and other persons who on account of
training or professional experience have an overview of the dangers which can develop when
operating the instrument.
Personnel without this training or persons who are currently being trained require careful instruction.
The present Operation Manual serves as the basis for this.
2 Safety
2.2 Proper use
The instrument has been designed and built for laboratories. It serves for the neutralization and
adsorption of gases that arise during chemical reactions and syntheses.
Only gases with known chemical composition may be drawn off.
2.3 Improper use
Applications not mentioned above are improper. Also, applications, which do not comply with the
technical data, are considered improper. In particular no gases with unknown chemical composition
may be drawn off.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
The operator bears the sole risk for any damages caused by such improper use.
The following uses are expressly forbidden:
• Use of the instrument in rooms which require ex-protected instruments.
• Use on samples, which can explode or inflame (example: explosives, etc.) due to shock, friction,
heat or spark formation.
• Use in overpressure situations.
• Drawing off liquids.
• Drawing off solvents.
• Drawing off vapors of organic solvents.
• Use for cleaning of room air.
