Abstract

Focusing on the ventilation problems of cisterns in confined space operations, this study takes the cistern of Building 1, Xinhongxia Residential Quarter in Shanghai as the research subject. Comparative experiments were carried out to investigate the effects of natural ventilation and mechanical ventilation. Adopting equipment such as a pump-suction four-in-one gas detector and axial flow fan, the changes of oxygen concentration in the cistern under different ventilation modes were measured. The results show that mechanical ventilation has significant advantages in improving the oxygen level inside the cistern, which can provide a reference for the selection of ventilation schemes for similar confined spaces.
