The aim of this research project was to determine the rate at which oxygen depletes in enclosed spaces. Cargo holds, chain locker and double bottom tanks are only some of the enclosed spaces found on a ship. The project was conducted using oxygen depletion experiments on scrap metal in sealed and open vented containers. In addition, the speed of oxygen depletion in a replicated chain locker is investigated. It is necessary to highlight the speed of oxygen depletion in cargo hold situations and other enclosed spaces and prevent loss of life in these dangerous spaces.In the oxygen-depleted atmosphere within an enclosed space, there is no sensory indication to cause alarm regarding the dangers within that space. Therefore the results of the experiments must be seen as a significant step in raising awareness of the dangers within an enclosed space, in improving health and safety standards and preventing loss of lives at sea.

封闭空间中的氧气消耗

该研究项目的目的是确定封闭空间中氧气消耗的速度。货舱、链锁柜和双层底舱只是船上封闭空间的一部分。该项目是在密封和开口通风容器中对废金属进行耗氧实验进行的。此外，研究了复制链锁中的氧气消耗速度。有必要突出货舱情况和其他封闭处所内氧气消耗的速度，防止在这些危险处所内造成生命损失。 在封闭空间内的氧气耗尽气氛中，没有感官指示引起危险警报在那个空间内。因此，必须将实验结果视为提高对封闭空间内危险意识的重要一步，
