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

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
