What if the policy requirements are different?

During a visit to the biomass ethanol production plant, the plant manager raised an issue: VOC levels detected inside the plant premises were above the allowed limits. The environmental protection authorities require that all factory buildings be fully sealed to prevent VOC leaks. The safety supervision department intervened after an inspection, stating that ethanol emissions could cause explosions. Inconsistent policies – not sure how to handle it? Do anyone have any solutions or similar cases?
There has long been a conflict between safety regulations and environmental protection requirements regarding whether factory buildings should be enclosed. From a safety perspective, standards recommend that equipment be installed in an open or exposed manner; however, environmental protection demands that everything be enclosed, including the equipment itself and the factory buildings； In recent years, environmental protection has received significant attention, which is why more and more factories are now being made airtight ； However, from the perspective of intrinsic safety and source control, it is necessary to consider how to prevent VOCs from being released or to minimize such releases into the environment at the source.
It is necessary to distinguish between volatile gases generated during the manufacturing process and biogas produced during the treatment of waste materials. When process exhaust gases exceed the specified limits, it is necessary to implement source control, improve capture efficiency, and add more treatment facilities.
