Investigation of the safe location for private electric power generators servicing residential buildings in Nigeria

Abstract

This study focused on the safe location for electric power generators servicing detached bungalows in the Nigerian environment via the determination of the air quality impact of primary air pollutants including carbon monoxide (CO), oxides of nitrogen (NOx), sulphur dioxide (SOx ), particulate matter (PM) and volatile organic compounds (VOCs). The AERMOD view air emission dispersion modelling commercial software was used to predict the ground-level concentration of air pollutants entering buildings. These were compared with Nigeria’s National Ambient Air Quality Standards (NAAQs) and WHO air quality standards to determine the indoor air quality impacts and predict the safe location for electric power operations. The results showed that predicted ground-level concentrations of CO, NOx, SOx, PM and VOCs from electric power generators located at both 1 m and 4m from the residential building of interest at the various hours considered were within limits. However, it was observed that the location of generators at 1m or beyond from the house is relatively good and safe to limit hazards from air emissions. The findings will assist relevant authorities and individuals in developing and implementing a strategic air quality management plan for the safety of residential building occupants.
