Parking Garage Air Quality (Vehicle Exhaust Infiltration, PM2.5, NO2, CO) — household safety profile
Moderate riskParking garages attached to or below office buildings are a significant source of vehicle exhaust infiltration: PM2.5, NO2, CO, benzene, formaldehyde, and ultrafine particles from engine idling, cold starts, and tire/brake wear.
What is this product?
Parking garages attached to or below office buildings are a significant source of vehicle exhaust infiltration: PM2.5, NO2, CO, benzene, formaldehyde, and ultrafine particles from engine idling, cold starts, and tire/brake wear. Underground garages: mechanical ventilation required (IBC/IMC: 0.75 CFM/sq ft or CO-sensor-based demand ventilation). Exhaust infiltration pathways: elevator shafts, stairwells, HVAC outdoor air intakes located near garage exhaust, and pressure differentials pulling garage air into adjacent retail/office. CO is the acute concern (garage CO alarm standard: 35 ppm for 1-hour, 200 ppm immediate action). NO2 and PM2.5: chronic health concern for workers stationed in garages (attendants, valets, security). EV transition: will eventually eliminate tailpipe emissions in garages but not tire/brake particulate.
