Preparatory measures

3.1

Certificate of decontamination

The decontamination of the safety cabinet is the re-
sponsibility of the operator.
The operator issues hygiene regulations that are
compatible with the intended purpose of the unit.
Prior to repairs, inquire about the existing hygiene
regulations and also about decontamination and dis-
infection measures.
If disinfection is required prior to repairs, use the stan-
dard disinfection procedures suitable only for micro-
biological application as described in Annex A.
NOTE! – Decontamination certificate!
Ask the operator for a written proof of the ap-
plied decontamination procedures. The decontamina-
tion certificate should be attached to the test report.
