Indoor Air Quality Awareness Briefing

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)



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



IAQ IncidentsCommon Causes

• Construction/Renovation projects and activities – Nuisance odors, vapors, dust, etc. from products, chemicals

used during construction activities



IAQ IncidentsCommon 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)



IAQ IncidentsCommon 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).



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



Communication

• Designate an individual (i.e. SECM) to respond promptly to potential IAQ issues – Liaison between facility and resident engineer and/or

project manager



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.



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



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

and District Office or SSC Manager – For construction & maintenance activities with

potential EOSH-related impacts – To assess and reassess hazards during project



Planning - FAA Order 3900.57

• Section 3 – Project Hazard Risk/Analysis• Potential IAQ hazards shall be identified

• Section 4 – Site Safety and Health• IAQ controls shall be addressed and risks mitigated.• Consult an EOSH professional as needed• Ensure FAA Hazard Communication requirements are in

effect and remain so throughout the project



Pre-Construction Meeting

• Ensure compliance with the following: – FAA Form 3900-8 completed and reviewed

– Hazard Communication requirements (29 CFR 1910.1200)

– MSDSs submitted for review

– EOSH expectations discussed and understood by all affected parties

– Project Engineer must review all required EOSH permits

– Brief management and employees as required (i.e. new materials, processes, project activities in order to minimize/mitigate risks to employees and NAS operations



Pre-Construction Meeting

• Project-specific IAQ mitigation must be discussed and implementation requirements accepted by appropriate parties– Controlling outdoor air intake – Installing dust barriers – Additional ventilation – Proper storage/disposal of hazardous materials – Air monitoring equipment



Construction

• Facility Emergency Plans– RE and Facility Manager (includes ATO-T, ATO-E,

and ATO-W) shall review and revise • based on identified hazards following Pre-Construction

Meeting.

– Plans to be reviewed: • Occupant Emergency Plan • Asbestos Contingency Plan • Continuity of Operations Plan



Roles and Responsibilities

• Resident Engineer – Ensure facility systems are installed and performing

to meet owners EOSH performance requirements – Document all system testing results

• Provide to building owner prior to acceptance

– Validate that system performance and configuration meet the design basis and intent

– Ensure system manuals are delivered to the building owner and system training is provided

– Keep Facility Managers informed of all IAQ related issues/activities



Roles & Responsibilities

• Resident Engineer – Safety briefings must be conducted between the RE and

the Facility Manager– Utilize Form 3900-8 – Review and revise facility emergency plans – Review all sections of MSDSs, communicate concerns to

the SECM, and ensure chemicals are used as intended– Daily inspection / coordination to keep nuisance odors /

fumes / dusts/ vapors from entering FAA workplaces– Review all product information (i.e. carpet for off-

gassing); communicate concerns to the SECM




• Project Engineer – Coordinate review of project design with Engineering

Services EOSH Professional and SECM – Ensure project activity information provided to

employees prior to start of work activities – Safety briefing and project review must be

completed and documented as appropriate between the RE and a facility designee




• Project Managers– Consider IAQ requirements in construction,

installation, commissioning, and modifications phases

– Include Engineering Services EOSH professional and SECM in the review of project documents, risk management planning and the coordination of the project

– Incorporate applicable IAQ regulatory requirements and consensus standards into contract documentation




• Facility Manager – Assist individuals performing IAQ evaluations – Ensure HVAC systems are maintained regularly – Initiate investigations of worker complaints related to

IAQ – Maintain documentation of all IAQ complaints,

investigations, and subsequent resolutions– Maintain MSDSs on-site




• Facility Manager – Invite Bargaining Unit representatives to Pre-

Construction meetings – Review and revise facility emergency plans – Inform facility employees of upcoming project

activities prior to start of construction – Ensure compliance with Hazard Communication

program requirements and keep employees duly informed

General Activities

• Preparation– 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



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



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



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)



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



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




• Cleaning Products – Replace with less hazardous products – Take steps to reduce exposures to contaminants

from cleaning products• E.g. adequate ventilation, proper PPE (gloves)

• Janitorial procedures – Evaluate procedures

• Cleaning Chemicals/Products– Review MSDSs to ensure chemicals do not increase

worker exposure




• Use HEPA Filtered vacuums • Carpet Cleaning

– Use adequate extraction methods for wet carpet cleaning

– Ensure carpet or other porous materials do not remain wet for more than 48 hours



Off-Gassing

• New materials/furnishings may emit organic compounds – Increase ventilation with outdoor air during and

immediately after installation – Delay re-occupancy of space when possible
