Evaluation of Air Pollutants in Nonroad Diesel Construction Equipment Cabs
Previous research indicates that air quality near the cabs of nonroad diesel equipment may exceed recommended exposure limits for certain pollutants. The objective of this case study was to collect and analyze air pollutant data near the cabs of nonroad diesel equipment while performing real-world activities. Using state-of-the-art instrumentation, the research team conducted 24 tests on nine different items of nonroad equipment. The team collected data related to pollutant concentrations of carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, particulate matter, and black carbon. Average concentrations of carbon monoxide and nitric oxide did not exceed published exposure limits on a consistent basis, but their maximum values occasionally exceeded the limits. Carbon dioxide concentrations frequently exceeded recommended levels for adequate ventilation. The most concerning results belonged to particulate matter and black carbon. Concentrations of respirable particulates often exceeded recommended levels on a sustained basis. Overall, the case study yielded enough information to conclude that studying near-cab air quality in nonroad equipment cabs is necessary to reduce hazards related to human health, safety, and productivity for equipment operators.
