Exploding scuba tanks are rare and devastating events. But in cases such as the 1981 blast that cost a Lakeland man his legs, the cause of the explosions appeared to be catastrophic failure of the pressurized metal tanks — not the gases inside the tanks.

Can you breathe 100 oxygen?

Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can’t see properly, and your lungs, so you can’t breathe normally. So breathing pure oxygen is quite dangerous.

Do divers breathe pure oxygen?

Contrary to popular belief, scuba divers don’t only breathe oxygen underwater. After all, we don’t breathe pure oxygen above water either. … Divers go way deeper and explore much longer with mixtures such as nitrox, heliox, and hydrox as these are safer alternatives to simple compressed air.

What air do divers breathe?

Deep sea divers normally breathe a mixture of nitrogen and oxygen, called nitrox or EAN (Enriched Air Nitrox). While Earth’s atmosphere is 78% nitrogen and 21% oxygen, nitrox is typically 32-36% oxygen.
