Cleaning and Decontamination
Decontamination Procedure
Several procedures can be applied for decontaminating the safety cabinet. Which
procedure is selected, depends on:

the potential risk imminent in the agents,

the degree of purity required by an experiment or by a work process.
Possible decontamination procedures:
Wipe/spray disinfection:
is the standard disinfection procedure for cabinets used for
microbiological experiments.
UV disinfection: is particularly suited as an intensifying additional disinfection after a
wipe/spray disinfection.
Sterilization with steam: can be used for treating the removable stainless steel
components. Examples of autoclavable components are the bezels of the UV lamps, the
workplate or workplate segments and the armrests.
Disinfection with formaldehyde: can be performed if a sterile sample chamber is
required for the work process. This sterilization procedure is mandatory:

when filters are replaced,

when the device is shut down,

when the device is discarded.
Wipe/Spray Disinfection
The wipe/spray disinfection is performed in three stages:

predisinfection,

cleaning,

final disinfection.
NOTE
Before cleaning and UV disinfection the covers of the UV lamps must be
removed and afterwards installed.
