Indoor Air Quality in Construction Equipment Cabs

Indoor Air Quality in Construction Equipment Cabs

Equipment operators have reported that odor from the emissions were evident in the equipment cab. This research sought to answer the question of whether equipment emissions were affecting the Indoor Air Quality for construction equipment cabs. Construction equipment is well known as one of the greatest offenders for emissions. Non-road diesel engines are now governed by the EPA Tier 4 emission requirements. Although the Oklahoma Department of Environmental Quality (ODEQ) collects air quality data for metropolitan locations and reports on air quality issues, little is known about the air quality in construction equipment cabs. Data was collected utilizing the AdvancedSense Indoor Air Quality (IAQ) sensors for Volatile Organic Compounds (VOC), Carbon Dioxide (CO2), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), temperature, relative humidity and barometric pressure. Each piece of equipment was idled for twenty minutes. During that time, readings were taken in the equipment cab.
