5 Addendum c Status: Issued for 3 rd public review Topic: Laboratory work areas a. Terminology coordinated with FGI Laboratory Work Areas vs. Laboratories b. Reduction allowed via ANSI Z9.5 risk assessment or active sensing of contaminants or appropriate surrogates approach

6 Addendum f Status: Pending 2nd Public Review Topic: Operating Room Air Distribution a. Provides a specific definition of the primary supply diffuser array. b. Clarifies that no more than 30% of the Primary Supply Diffuser Array may be used for non-diffuser items. c. Additional diffusers may be located outside of the Primary Supply Diffuser Array if needed to achieve required environmental conditions or air change rates.

7 Addendum g Status: Pending Publication Topic: Definitions of Operating & Procedure Rooms a. Continues re-definition of ORs & Procedure Rooms included in the 2014 FGI Guidelines. b. Deletes Class A, B, and C terminology and replaces with: - Operating Room - Procedure Room c. New definition of Operating Room is equivalent to Class B and C ORs previously. d. New definition of Procedure Room is equivalent to Class A ORs previously. e.

13 Current Issues Clarification of inpatient and outpatient filtration requirements Reduction of outpatient occupancy requirements Reduction of air changes in unoccupied spaces Clarification of Recirculating Room HVAC Units Terminology and space name coordination with FGI Residential healthcare requirements Natural ventilation

14 Future Issues Patient room air distribution Air change rate reductions Outside air intake separation from exhaust Pharmacy requirements (USP 797 & 800) Anesthesia exhaust Air distribution terminology
