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 years Majority of the incidents were construction-related Media attention from high profile IAQ incidents at FAA IAQ-related LR issues from several recent arbitrations Congressional 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 sewers migrate through floor drains Vapors from paint, mastic, and new carpet/furnishings Smoke and dust Construction-related activities Mold Moisture build-up; Water leaks; Standing water Exhaust gases from vehicles/jet engines/portable power tools Through outdoor air-intakes

4 IAQ Incidents Common Causes
Construction/Renovation projects and activities Nuisance odors, vapors, dust, etc. from products, chemicals used during construction activities Construction/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 equipment Proper equipment to identify contaminants Lack of management training in Appropriate incident response Occupational Safety & Health (OSH) and IAQ issues at construction/renovation projects Existing OSH Programs (i.e. Hazard Communication program requirements)

6 IAQ Incidents Common Issues
Emergency/Incident Response procedures Not clearly defined at ATC Facilities Employees not properly trained Communication Coordination Airport Authorities and FAA Facilities representatives/managers must increase communication Utilize programs already in place (Hazard Communication, Checklists, etc). Emergency Response – Employees not properly trained on emergency or evacuation procedures Coordination – Airport authorities and FAA facilities must increase communication of upcoming renovation activities

7 Communication Follow the prescribed FAA protocols for sharing information with building occupants prior to start of project (i.e. construction, asbestos) Project location and schedule Chemicals/products to be used Material Safety Data Sheets Disruptions to normal schedule Egress/exits

8 Communication Designate an individual (i.e. SECM) to respond promptly to potential IAQ issues Liaison between facility and resident engineer and/or project manager

9 Communication Prevent 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 recommendations Contract Specifications include: Notification and Hazard Communication requirements Scheduling to minimize occupant exposure and risk to facility operations Selection of building materials Protection of building systems including the HVAC system Use of isolation techniques, including barriers and negative pressure

11 Contract Administration
Ventilation and filtration requirements Work practices and housekeeping Material storage Final clean-up and facility restoration Close-out and commissioning criteria for new construction or renovations

12 Planning - FAA Order FAA Pre-Construction & Maintenance Project Safety & Health Checklist (Form ) Used by the RE, COTR, designated facility POC, and District Office or SSC Manager For construction & maintenance activities with potential EOSH-related impacts To assess and reassess hazards during project Specifically, this checklist is intended to: Promote sensitivity to potential EOSH hazards associated with projects and stress the importance of not disrupting NAS operations Assist in identifying and validating potential project hazards and associated risks Assist in preventing safety and health incidents/accidents and facility shutdowns Ensure appropriate contractor measures and controls are in place to address potential project hazards Facilitate discussion with the contractor regarding plans to prevent/minimize potential incidents/accidents Enhance coordination between EOSH professionals, project personnel and contractors Facility review of critical FAA EOSH procedures with contractors Raise EOSH awareness

13 Planning - FAA Order 3900.57 Section 3 – Project Hazard Risk/Analysis

Work shall be scheduled while building is unoccupied, whenever possible Use ventilation and containment strategies to prevent spread of contaminants Use fire retardant plastic sheeting/barriers Isolate areas and occupants from dust or pollutants generated during renovations Temporarily 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 air Do not erect barriers (e.g. new walls) that could prevent adequate movement of air Increased 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 located Do not disturb asbestos/ lead paint during repairs, renovation or maintenance activities If suspected/presumed asbestos containing materials (ACM) or lead paint may be impacted: Consult an EOSH professional Review the facility Operations and Maintenance Plan

28 IAQ Concerns Mold If mold and mildew are observed during renovations
Consult an EOSH professional Consult 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 used Choose the least toxic chemicals Avoid dust and spray formulations if possible baits, traps, or granules are the preferred formulations

30 Building Maintenance HVAC System
Coordinate with building management to discuss operation, and maintenance of the HVAC system Work with building management to ensure that system is balanced Ensure regular Preventive Maintenance is performed on window air conditioners and perimeter heating and cooling units e.g. regular filter change Recommend changing all impacted filters after a major rennovation or when IAQ related impacts were potentially involved
