The Russian Navy has had another horrible accident aboard a submarine. Some 20 sailors have died and many others were “poisoned”. It is very difficult from the article to tell why. From the article:
The deaths were caused by a Freon gas leak that occurred when the fire-control system was activated yesterday, according to a preliminary investigation by the Russian Prosecutor’s Office, Vesti reported, citing Vladimir Markin, spokesman for the Prosecutor’s investigative committee.
Huh? I don’t know a lot about submarine construction, but I do know a lot about “Freon”. Freon is a trade name used by the DuPont corporation for refrigerants. There are many different types of refrigerants, and “Freon” doesn’t describe which one. Most refrigerants that are commonly used in refrigeration and air conditioning applications are non flammable and very low in toxicity. I can see how people in the sub would suffer greatly if a large refrigerant leak occurred, as there is only so far refrigerant can go in such a small space. But you would think a modern sub would have some sort of way to replace their air with stored oxygen.
Lastly, modern refrigerants operate under pressure, and are closed systems. How did a faulty fire control system rupture a refrigerant line?
It may be a poor translation of an article originally in Russian (too bad I don’t have it or Tatyana or John Jay could take a look at it) or just the Russian news service providing scarce details provided them by the Russian Navy. Any way you slice it, the article makes little to no sense.
I feel for the families of the Russian sailors and wish them the best. I also hope that the Russian navy starts to maintain their sub fleet a little better so I don’t have to keep reading about their sailors losing their lives.
