CDC GUIDELINES FOR EIC CDC Guidelines- Major Air Quality Issues Air Sampling External and Internal demolition- Are Barriers Required?  Working with plumbing in sensitive areas  Exposure of ceiling spaces  Crawling into ceiling spaces  Work on elevator shafts  Demo of wallboard, plaster, ceramic tile, ceiling tile Environmental Infection Control > Regulations & Guidelines

16. CDC GUIDELINES FOR EIC (CONT.)  Major Air Quality Issues (cont.)  Removal of flooring  Removal of windows and doors  Removal of casework  HVAC systems design and filtration  HVAC maintenance and repair  duct cleaning  system shutdown  moisture in system  backup emergency power Environmental Infection Control > Regulations & Guidelines

17. AIA GUIDELINES (CHAPTER 5) For all new construction and renovation Consultation from infection control professionals, and safety professionals Development of an ICRA Initiated in planning and design and continued through construction/renovation Performed by multi-disciplinary panel Documented!! Environmental Infection Control > Regulations & Guidelines

18. CHAPTER 5 ICRA- BASIC ELEMENTS  Impact of disrupting essential services  Patient placement and relocation  Placement of barriers  Evaluation of ventilation needs  Number of AII and PE rooms  Patient protection from:  Demolition  Un-planned outages  Movement of debris  Patient flow through building Environmental Infection Control > Regulations & Guidelines

19. ICRA MATRIX  Aids in determining proper work practices and types of engineering controls, and monitoring required.  Assesses risk based upon the patient risk group and types of activities performed Environmental Infection Control > Risk Assessment

20.  Type A- (Inspection and Non-invasive)  removing ceiling tile for inspection  painting without sanding  wall-covering  electrical trim  minor plumbing  Type B (Work Activities)  Small scale/ short duration  Minimal dust created ICRA Matrix (cont.) Environmental Infection Control > Risk Assessment

21. Type C (Work Activities)  Demolition/removal of fixed building parts  Moderate-high dust, including sanding, flooring removal, ceiling tiles & casework, major cabling,  Can’t be done in 1 shift Type D (Work Activities)  Major demolition/construction  High dust created, including heavy demo, removal of walls, new construction  Required consecutive work shifts ICRA Matrix (cont.) Environmental Infection Control > Risk Assessment

22. Containment of Dust and Debris  Controlling construction related activities  Envelope penetrations  Building shafts, chutes, stairwells and elevators  Removal of materials from building  Electrical and water system shutdowns  HVAC system shutdowns, potential for passive ventilation Engineering Controls Environmental Infection Control > Engineering Controls
