4. Ventilation and VOC containment

In the case of VOC emissions from a fixed source, or due to diffuse emissions, in a workshop for example, the first step is to limit the concentration in the ambient air in order to protect the health of operators, while complying with the maximum values or exposure limits imposed by regulations. This entails ventilating and then channelling effluents loaded with volatile organic compounds. In order to reduce the volumes to be ventilated, and therefore air flow rates, the containment of certain emission zones can prove to be an interesting operation.
