Which AAMI standard provides primary guidance on the design and layout of endoscope reprocessing areas?
Answer: AAMI ST91
AAMI ST91 is the primary standard addressing flexible endoscope reprocessing, including facility design requirements.
What is the recommended minimum number of sinks in the decontamination area of an endoscope reprocessing room?
Answer: Two sinks — one for washing, one for rinsing
At minimum, two separate sinks should be available — one dedicated to washing and one to rinsing — to prevent cross-contamination.
Why is a hands-free (foot-pedal or sensor-operated) faucet preferred in the decontamination sink area?
Answer: It prevents recontamination of cleaned hands during rinsing
Hands-free faucets prevent technicians from recontaminating their hands or the scope by touching a potentially soiled handle after cleaning.
The 'clean-to-dirty' workflow principle in endoscope reprocessing means that:
Answer: Personnel and scopes should move from decontamination toward clean/storage areas, never in reverse
Unidirectional clean-to-dirty workflow prevents contaminated items from re-entering clean zones and causing cross-contamination.
What is the purpose of a pass-through window between the decontamination area and the clean processing area?
Answer: It enables scopes to move from dirty to clean sides without personnel crossing zones
Pass-through windows allow scopes to be transferred from decontamination to the clean side without staff or scopes crossing contamination boundaries.
Which ventilation parameter is most critical to maintain in the decontamination area to protect staff from chemical vapors?
Answer: Negative air pressure relative to adjacent areas
Negative air pressure in the decontamination area contains chemical vapors and biological aerosols, preventing them from migrating to clean zones.
How should soiled endoscopes be transported from the procedure room to the reprocessing area?
Answer: In a sealed, leak-proof container or covered transport cart
Soiled scopes must be transported in sealed, leak-proof, labeled containers to protect staff and the environment from contamination.
