2Infection Control During Construction & Renovation Issues and ConcernsPreconstruction PlanningContaminants Generated By ConstructionProper Containment and IsolationPost-Construction & Clean-upDevelopment of Infection Control PolicyNova Environmental, Inc.
3Issues and Concerns Unique concerns in hospitals… Continual occupancy Increased suseptability - ImmuneDeficiency/HAI(Hospital Acquired Infection)Construction’s effect onaccessibility and impacton emergency planningNova Environmental, Inc.
4Issues and Concerns Unique concerns in hospitals “Minor problems can be deadly”Jackhammer could dislodge years of build-up in plumbing system, releasing bacteria into the water supply.Dust from drywall demolition could enter the HVAC and disperse to operating areas.Rain could blow into open windows, creating moisture intrusion that can lead to mold growth.Nova Environmental, Inc.
5Pre-Construction Planning Complete an ICRA (infection control risk assessment)Documented guideline.Diverse group of employees involved, including infection control staff.Begins early in design stage.Intended to evaluate design and construction’s impact on occupants and the environment.Nova Environmental, Inc.
6Pre-Construction Planning Design Design to support infection control and in compliance with relevant guidelines, standards, codes and regulations.HVAC, recommended ventilation and filtrationMechanical systems involving water supply and plumbingNumber and type of hand-washing fixtures, soap, paper towels, lotionsSharps disposal unit placementAccommodation for PPEType of surfaces, ceiling tiles, walls, counters, floor coverings, furniture, etc.Nova Environmental, Inc.
7Pre-Construction Planning Location of Construction Proximity to high risk areas (Surgery, Mother/Baby, Intensive Care, Emergency Room, Oncology, etc.)Nova Environmental, Inc.
8Pre-Construction Planning Extent of Construction Size of work areaLength of construction scheduleScope and degree of activitiesNumber of workersContractor shiftsAccessibility, egressExternal excavation/constructionNova Environmental, Inc.
9Pre-Construction Planning Type of Construction Demolition of componentsPre-planning for asbestos, lead, mold, dust & debris generationEvaluation of HVAC isolationShut off or rerouteNegative/postitive air pressureConstruction area air filtration and movementInstallation of new furnishings and building componentsOdors (VOCs)Nova Environmental, Inc.
10Pre-Construction Planning Type of Containment Intent is to ensure complete isolation of potential construction contaminants from building occupants and environmentNeeds to be detailed and identified within construction documentsCoordination through construction managers or general contractorsDetermination of standards for accountabilityNova Environmental, Inc.
11Pre-Construction Planning Monitoring – Determine Cleanliness Consider air monitoring, especially when construction is adjacent to high risk areasConsider establishing criteria for level of cleanliness expected upon completion of construction work, (visual, clearance sampling)Nova Environmental, Inc.
12Contaminants Generated By Construction AsbestosFibrous mineral that can be incorporated into any building component (inhalation hazard)Nova Environmental, Inc.
13Contaminants Generated By Construction LeadElement that has commonly been used in paint and incorporated into drywall used in X-Ray areas of hospitals (inhalation and ingestion hazard)Nova Environmental, Inc.
14Contaminants Generated By Construction MoldFungi that can develop or grow on organic building components (inhalation and ingestion hazard)Nova Environmental, Inc.
15Contaminants Generated By Construction BacteriaPotentially hazardous microorganisms that have needs similar to mold, nutrients and moisture (various routes of entry)Nova Environmental, Inc.
16Contaminants Generated By Construction Dust and DebrisParticulate (and potential fumes) common during construction and renovation (inhalation hazard)Nova Environmental, Inc.
17Proper Containment & Isolation Isolation of construction zones from rest of buildingSmall short projects with minimal dust generation, fire rated polyethylene, sealed entrywayLarger projects require rigid dust-proof and fire rated barrier walls, (such as drywall) with caulked seams for tight sealAll stationary items seal with critical barriersBarrier to extend above ceilings, below floors (tunnels) if applicableVerify that everything is properly sealed(Need to consider egress and accessibility issues)Nova Environmental, Inc.
23Proper Containment & Isolation HVACShut off or temporarily modifyCritical barriers over all vents/diffusers/ductsConstruction must be under negative pressure with respect to adjacent areas at all times, may need portable ventilation systemsExhaust from construction should be exhausted directly outside if at all possible. If re-circulated, must be flowed through HEPA filtration systemNova Environmental, Inc.
25Proper Containment & Isolation DecontaminationEnsuring workers and equipment coming out of construction zone don’t contaminate non-construction areasWorkers to HEPA vacuum dust/debris off cloths prior to exiting work areaTacky mats and disposable boot coverings should be usedEquipment and supplies cleaned prior to exiting work areaDebris removed from construction sites in carts with tight- fitting coversDesignate elevators for construction traffic onlyAdjacent areas mopped daily or as needed to control dustNova Environmental, Inc.
27Post-Construction & Clean-Up Plans should include vacuuming of construction areas and flushing debris from water systems before re-occupancySufficient ventilation to vacate odors from new furnishingsAll surfaces within construction zone should be dust-freeVisual inspection by hospital representatives a mustNova Environmental, Inc.
28Post Construction Sampling Intended to document that renovated area is “safe” for re-occupancy.After cleaning, prior to barriers being removedConsider:General particulate air samplingDust sampling for leadTO sampling for VOCsNova Environmental, Inc.
29Post Construction Cleanup Clean during process of barrier dismantlementFinal cleaning of areas, including locations of barriers. This should be performed with HEPA vacuums, not brooms!Nova Environmental, Inc.
30Development of Renovation Construction Infection Control Policy Written program with following components:Infection Control Risk AssessmentConstruction Design PhaseRequirements for containment & IsolationContaminant control methodsPost-construction cleanup and samplingClearance criteriaNova Environmental, Inc.
31Presentation SummaryEnsure that infection control staff are involved from initial stages of design;Ensure that infection control procedures are taken seriously by all contractors and that there is accountability;Ensure that post-construction cleanup is extremely thorough;Consider third party clearance sampling to provide occupant documentation of cleanliness.Nova Environmental, Inc.
