RMG factories in tropical regions like Bangladesh often lack adequate ventilation and cooling systems, leading to dangerously high indoor temperatures, especially during hot seasons. This heat stress poses significant health risks to workers. A study by Hokkaido University, published in the journal Sustainable Cities and Society, analyzed the monthly indoor heat stress in Dhaka’s RMG factories, focusing on Wet Bulb Globe Temperature (WBGT) and Predicted Heat Strain (PHS).
The research highlighted alarmingly high heat stress levels from May to July, sometimes reaching 38°C. It revealed substantial temperature variations within factory zones and emphasized the urgent need for effective cooling systems to protect workers’ health. The study’s simulations indicated that without proper cooling, indoor temperatures frequently exceed safe levels, particularly from May to August.
