1 Indoor Air Quality Awareness Briefing For Presentation to:Project Managers, Resident Engineers, Facility Managers, & Facility Representatives
2 Background Recent Indoor Air Quality (IAQ) Issues at ATO Facilities Over 50 IAQ incidents at ATC facilities over the last 3 yearsMajority of the incidents were construction-relatedMedia attention from high profile IAQ incidents at FAAIAQ-related LR issues from several recent arbitrationsCongressional Hearing (7/24/07)The majority of the incidents were construction-related caused by the following circumstances:• Vapors/ irritants/ gases entering the ATC facility through ventilation system outdoor air intakes;• Building material being used by a contractor, who did not submit associated material safety data sheets (MSDSs) to the FAA for those products;• Construction products intended for outdoor use were used indoors introducing pungent odors indoors, without adequate ventilation; and, The contractor simply did not follow the standard operating procedures for material application that it submitted to the FAA.Media attention at Detroit Tower related to mold from excess moisture and standing water.
3 FAA IAQ Incidents Internal and External sources Odors from natural gas and sewersmigrate through floor drainsVapors from paint, mastic, and new carpet/furnishingsSmoke and dustConstruction-related activitiesMoldMoisture build-up; Water leaks; Standing waterExhaust gases from vehicles/jet engines/portable power toolsThrough outdoor air-intakes
4 IAQ Incidents Common Causes Construction/Renovation projects and activitiesNuisance odors, vapors, dust, etc. from products, chemicals used during construction activitiesConstruction/renovation projects and activities – Products and chemicals used are introduced into work areas inside the building through improper ventilation and/or entrainment through intake or supply vents
5 IAQ Incidents Common Issues Lack of monitoring equipmentProper equipment to identify contaminantsLack of management training inAppropriate incident responseOccupational Safety & Health (OSH) and IAQ issues at construction/renovation projectsExisting OSH Programs (i.e. Hazard Communication program requirements)
6 IAQ Incidents Common Issues Emergency/Incident Response proceduresNot clearly defined at ATC FacilitiesEmployees not properly trainedCommunication CoordinationAirport Authorities and FAA Facilities representatives/managers must increase communicationUtilize programs already in place (Hazard Communication, Checklists, etc).Emergency Response – Employees not properly trained on emergency or evacuation proceduresCoordination – Airport authorities and FAA facilities must increase communication of upcoming renovation activities
7 CommunicationFollow the prescribed FAA protocols for sharing information with building occupants prior to start of project (i.e. construction, asbestos)Project location and scheduleChemicals/products to be usedMaterial Safety Data SheetsDisruptions to normal scheduleEgress/exits
8 CommunicationDesignate an individual (i.e. SECM) to respond promptly to potential IAQ issuesLiaison between facility and resident engineer and/or project manager
9 CommunicationPrevent Nuisance Dusts, fumes, vapors & odors from entering your facility.Look for potential sources in your facility and from nearby projects. Coordinate with personnel performing the work to ensure that these nuisance contaminants do not get into the workplace at FAA facilities through fresh air intakes or HVAC systems.
10 Contract Administration Contract language should include IAQ specifications and recommendationsContract Specifications include:Notification and Hazard Communication requirementsScheduling to minimize occupant exposure and risk to facility operationsSelection of building materialsProtection of building systems including the HVAC systemUse of isolation techniques, including barriers and negative pressure

25 General Activities Preparation Work shall be scheduled while building is unoccupied, whenever possibleUse ventilation and containment strategies to prevent spread of contaminantsUse fire retardant plastic sheeting/barriersIsolate areas and occupants from dust or pollutants generated during renovationsTemporarily relocate occupants when necessary
26 General Activities Ventilation Avoid cutting off outdoor air supply Do not enclose a pollutant source (e.g. copiers) in areas with inadequate exhaust or supply airDo not erect barriers (e.g. new walls) that could prevent adequate movement of airIncreased housekeeping may be necessary in the immediate work area and also in the rest of the building. Ensure that workers and equipment leaving work areas do not contaminate other parts of the building. Effective practices may include walk-off mats, the use of removable coveralls, and wiping down equipment before exiting the work area.
27 IAQ Concerns Asbestos / Lead Paint Review Asbestos Survey Inventories to determine where presumed asbestos containing material/asbestos containing material (PACM/ACM) are locatedDo not disturb asbestos/ lead paint during repairs, renovation or maintenance activitiesIf suspected/presumed asbestos containing materials (ACM) or lead paint may be impacted:Consult an EOSH professionalReview the facility Operations and Maintenance Plan
28 IAQ Concerns Mold If mold and mildew are observed during renovations Consult an EOSH professionalConsult the Indoor Air Quality Implementation Guidance (http://ats.awa.faa.gov/aaf/afz/800/afz800frame.htm)
29 IAQ Concerns Pesticide Use Ensure that only necessary and appropriate pest control practices are usedChoose the least toxic chemicalsAvoid dust and spray formulations if possiblebaits, traps, or granules are the preferred formulations
30 Building Maintenance HVAC System Coordinate with building management to discuss operation, and maintenance of the HVAC systemWork with building management to ensure that system is balancedEnsure regular Preventive Maintenance is performed on window air conditioners and perimeter heating and cooling unitse.g. regular filter changeRecommend changing all impacted filters after a major rennovation or when IAQ related impacts were potentially involved
31 Building Maintenance Cleaning Products Janitorial procedures Replace with less hazardous productsTake steps to reduce exposures to contaminants from cleaning productsE.g. adequate ventilation, proper PPE (gloves)Janitorial proceduresEvaluate proceduresCleaning Chemicals/ProductsReview MSDSs to ensure chemicals do not increase worker exposure
32 Building Maintenance Use HEPA Filtered vacuums Carpet Cleaning Use adequate extraction methods for wet carpet cleaningEnsure carpet or other porous materials do not remain wet for more than 48 hours
33 Off-Gassing New materials/furnishings may emit organic compounds Increase ventilation with outdoor air during and immediately after installationDelay re-occupancy of space when possibleExamples of products that may off-gas include: wall paneling, draperies, composite wood furniture and cabinets, cubicle dividers, carpet and vinyl flooring, paints, finishes, and adhesives.
