Preservation and expertise: disinfection

For collections infested by insects, molds or bacteria, the Disinfection Unit of the Bussy-Saint-Georges Technical Center (Unité de désinfection du Centre technique de Bussy-Saint-Georges) offers ethylene oxide based disinfection.

Processing control

The three steps process is monitored by the laboratory from beginning to end.

  • The documents are kept in a pre-conditioned environment (20°C – 60%) for at least three days.
  • They are treated with a solution combining ethylene oxide with an inerting gas (CO2).
    • Contact length: 7 hours
    • Concentration: about 650 mg/l
    • Process temperature: 25°C
  • Two steps desorption of residual ethylene oxide
    • At least 10 rinse cycles under vacuum;
    • then, at least two weeks in the desorption room (20°C, 50%).

The whole process implies that the collections should not be moved for approximately one month. The scheduled return date can be given when the document is delivered.
Important to know: the documents should not have been formerly treated with chlorinated insecticide components such as mothballs.

The cost of processing is 240 euros (excl.tax) per square meter.
(This rate does not include transportation and insurance).
