Monitoring air pollution and mitigation for workplace safety at a Cement Factory in India - Case Study
The fugitive emissions (PM2.5 & PM10) from the cement factory was a huge concern for the employees as it was putting their health at risk. Eager to tackle this issue, they tried many different solutions from across the world, but in vain. Most of them were filter-based and proved to be futile on fugitive emissions, especially from the bags getting loaded onto the transport vehicles. Additionally, they needed a real-time and accurate system for monitoring air pollution and tracking the hazardous pollutants in the air.
Two of Oizom’s ambient dust monitoring systems- Dustroid were installed at the cement factory to monitor the air quality and measure the concentration of dust particles in the air. It also empowered the EHS team to better understand the extent of the problem. After assessing the air quality for about a week, Oizom’s solution partner- Devic Earth deployed its Pure Skies technological solution. The air quality was monitored again with Dustroids on a weekly basis to observe the gradual change. The comparison was done weekly to ensure comparability of air quality data that typically is dependent on the activity (which varies day-to-day but is predominantly similar across weeks). As an external module, wind sensors were installed on the two Dustroid units which also gave meteorological insights.
In conclusion, after monitoring air pollution with Oizom Dustroids and clearing the pollutants with Devic Earth’s Pure Skies technology, there was a rapid increase in the air quality levels. Most importantly, after only about 4 weeks, there was a 42% reduction in PM2.5 and a 50% reduction in PM10, making the air safer and cleaner for all their employees and people living in the area.
