What is the required negative pressure differential for the soiled/decontamination zone of an endoscope reprocessing area?
Answer: Negative pressure relative to adjacent areas — to contain airborne contaminants within the decontamination zone
Negative pressure in the decontamination zone prevents airborne contaminants from migrating to adjacent clean areas.
Why is staff hand hygiene a critical component of the endoscope reprocessing workflow?
Answer: Hand hygiene prevents technicians from transferring microorganisms from contaminated scopes to their own mucous membranes or to reprocessed items
Hand hygiene before and after PPE use, when moving between dirty and clean zones, and before handling reprocessed items prevents cross-contamination.
What minimum temperature must rinse water reach during AER cycles to be effective?
Answer: The temperature specified by the AER and disinfectant manufacturer's IFU — typically 20–35°C depending on the chemical
AER rinse water temperature requirements are specified by the manufacturer's IFU; most chemical HLD agents have validated temperature ranges that must be maintained.
How should chemical spills of HLD agents (glutaraldehyde, OPA, PAA) be managed in the reprocessing area?
Answer: Follow the facility's spill response protocol per the chemical's SDS: don PPE, contain the spill, neutralize or absorb with appropriate materials, and document the event
Chemical spills require immediate, protocol-driven response per the SDS to protect staff and properly manage hazardous material.
What is the purpose of designating specific personal protective equipment for the soiled and clean zones of the reprocessing area?
Answer: To prevent PPE worn in the contaminated zone from carrying pathogens into the clean zone
Zone-specific PPE ensures that contaminated outer garments are removed before entering the clean zone, preventing cross-contamination.
When should the reprocessing area be terminally cleaned and disinfected?
Answer: At minimum at the end of each day, with more frequent cleaning of high-touch surfaces between reprocessing sessions
Daily terminal cleaning removes accumulated contamination from all surfaces; high-touch surfaces should be disinfected more frequently during active reprocessing.
