Let's go back to September 23, 2007, when an emergency ship sailed to an oil rig near Yorkshire, England. The sound of the anchor striking woke Findley the sailor, and because of the loud noise, he woke up the other two sailors, Robert and Bob, who decided to go to the anchor cabin to deal with the noise.
However, no one would have imagined that tragedy would happen in the next second. Robert, the sailor who took the lead, walked into the anchor cabin first, but the next second he fainted. Almost at the same time, the second Bob to enter the room fainted. The last sailor, Findley, realizes that something is wrong after calling the team over the radio to no avail. So he wore a small emergency breathing apparatus and went to the anchor cabin to save people. But he inevitably fainted at the end.
By the time the rescue team found the three, they had all lost their vital signs due to suffocation. In the follow-up inspection, it was found that the real culprit who killed the three was none other than the "rust" that we commonly see in our daily lives.
Due to the humid air at sea, the hull and anchor chain are prone to rust. In addition, the anchor cabin is a confined space, and the oxygen content in the air in the cabin is less than 10%. It is important to know that under normal circumstances, the oxygen content in the atmosphere is about 21%. The oxygen content of the anchor cabin is less than 10%, which is already a serious oxygen deficiency, and the human body will feel drowsy in such an environment. When the oxygen content is less than 6%, the body will faint instantly and stop breathing.
Therefore, it is inferred that the oxygen content in the anchor cabin was already less than 6% at that time, which caused the suffocation of three crew members.
On 16 November 2006, a cargo ship loaded with wood pellets was loading and unloading at the port of Helsingborg, Sweden. At that time, a seafarer and a porter ran into the hold of the ship in order to get the crane to be aligned with the cargo. However, the moment the hatch opened, the two fainted one after another. After emergency rescue, only the porter was lucky to survive.
It turns out that wood not only absorbs oxygen, but also releases toxic gases such as carbon monoxide and ***. Although the wood had been ventilated for 8 hours before the two opened the hatchBut the carbon monoxide concentration in the cabin still reached a terrible 5416 parts per million. The safe carbon monoxide concentration range is less than 50 ppmThe terrible contrast between the two values is chilling.
Finally, back to the "rust" we mentioned above. Although it is very harmful and lethal, I found it when I was collecting information"Rust" is actually a kind of traditional Chinese medicine. In the "Materia Medica", there is also a mention of "the Yinghua of rust gets gold, its taste should be hard, and the air should be cold".
In other words, rust has the effects of clearing heat and detoxifying, calming the heart and calming the liver. But if you think about it, who will take a piece of rusty iron and gnaw it when it is on fire?
