Combating with poor Indoor air quality to improve work environment at IndianOil

ABSTRACT

Introduction: Indoor air quality have a great impact on physical and psychological health of employees working in buildings. IndianOil Institute of Petroleum Management (IiPM), located in National Capital Region of Delhi(NCR) is a premiere institute consisting of multiple training halls & auditoriums. In view of COVID-19 pandemic, modifications were carried out in air handling unit system at IiPM. Materials and methods: A detailed study of air movements, intake and return path was carried to find out measures to ensure adequate air exchanges. Additional air inlets with Dual PM10 filters were fixed on all air intake paths to reduce the pollutant level in air entering the building. The air handling unit at the institute was also fitted with special grade air filter for bringing down the PM2.5 level below 60. Special grade filters filtered the pollutants and reduced the pollutant level of air. An online air image sensor was installed to measure the quality of ambient air after filtration. Stand-alone air cleaner/filter units were also installed in training halls, lobbies and waiting areas. Result: Following modifications there was improvement in air quality by 90%. This resulted in building confidence level and provided a stress-free safe environment for employees working at the institute. Employees working at IiPM confirmed reduction in eye irritation, headaches and fatigue due to air pollution. Discussion: Installation of air filters inside the building helps in improving air quality which in turn prevents common health issues at workplace. This has prompted us to provide similar solutions in other office buildings in NC
