Freon gas (R-12 for instance) released into a standard pressure and temperature situation is heavy; it weighs much more, around five times more than the air it displaces. So it drops like a rock into spaces where it can’t drop any further, and pushes air out — causing suffocation.
Shipyard workers know that they need ventilation protection whenever freon might be released into a vessel’s hull.
Given that, it amazes me how “scientists” get away with telling people that Freon is responsible for damage to Earth’s upper altitude ozone layer.
Good point.
Good comments.
Facts are so inconvenient, sometimes.
The Freon that is up there is generated up there, just like the Ozone. The Freon regulates the size of the hole in the Ozone layer, which regulates the amount of energy that goes in at the North and South poles, which is used by the internal engine of the Earth.
The safety rules for Russian construction workers may be not as stictly enforced as they are here in the US.
It would seem that in a confined space, like a sub, there might not be time to don a mask and find the air-jack.
Do US Subs have Halon or Freon Fire suppression?
