SPB faced two serious challenges: -A hydrogen sulphide (H2S) leak in the FRP evaporator led to an unpleasant odour, prompting internal complaints from employees and impacting workplace satisfaction and productivity. -Measurements revealed a ten ppm H2S concentration in the ambient area, necessitating improved monitoring and mitigation measures. To address these concerns and prevent public grievances, SPB aimed to enhance workplace monitoring by efficiently detecting H2S leaks and implementing appropriate countermeasures to minimise odour and potential health risks.

SPB was searching for an odour detector with a display and relay output and found Oizom’s products to be excellent candidates. Initially, they were drawn to the multi-parameter Oizom Odosense, but they were seeking a more precise and budget-friendly option. Our astute partner stepped in, assessed the situation, and suggested focusing on H2S monitoring, the primary cause of the odour in their company. They recommended the single-parameter AQBot as a budget-friendly and effective solution for addressing their odour detection needs.

The AQBot was installed on the 4th floor FRP Evaporator area, near the H2S leak source, providing real-time H2S concentration data. This information was integrated with the company’s Distributed Control System (DCS), allowing for automated alarms when H2S levels increased. As a result, workers could evacuate the area and avoid exposure to hazardous gas, ensuring a safer working environment.
