A US Navy expert warned of the horrific health effects of being confined to a submarine, days before a tourist submarine carrying people to see the wreck of the Titanic disappeared.
In his research paper published in the Journal of Disaster Medicine on May 29, Dr. Dale Molly, former director of subsea medicine and radiological health in the US Navy, explained that there are many risks faced by commercial submarine passengers in the event of a malfunction, such as a lack of oxygen and carbon dioxide supplies. Toxic and low temperatures.
According to Molly, the submarines contain a carbon dioxide scrubber to remove excess toxic gases that accumulate when passengers exhale, but the capacity of this device has limits.
There is also a risk of hypothermia due to lower temperatures in the depths of the ocean, as well as hyperventilation caused by panic attacks, which can use up more oxygen.
“There is also a risk of exposure to elevated ambient pressures. If the battery runs out, the carbon dioxide cleaning system will stop working,” Molly added in his paper.
“People inside will find it difficult to breathe, and their breathing will deepen. They will get headaches and gradually become unconscious. The high level of carbon dioxide is what kills people first when they are in a sealed environment, not the oxygen level,” he said.
A report by the British newspaper “The Independent”, quoting rescuers working to search for the submarine, revealed the amount of oxygen reserves remaining for those on board.
The newspaper said that the rescuers, who are leading the search for the submarine, confirmed that the remaining amount of oxygen is sufficient for only 40 hours.
A rescue operation began in the deep waters of the Atlantic Ocean on Monday in search of a high-tech submarine carrying five people to document the wreck of the iconic Titanic, which sank more than a century ago.
The delay was reported Sunday night regarding 700 kilometers south of St. John’s, Newfoundland, according to the Canadian Joint Rescue Coordination Center in Halifax, Nova Scotia.
