How deep can you dive with an air tank?

There are depth limitations too, as nitrogen becomes narcotic the deeper you go. This becomes increasingly debilitating, so the maximum depth for recreational diving is 130 feet (40 m). Air itself becomes toxic as we go beyond 184 feet (56 m). Best used for: All recreational diving down to 130 feet (40 m).

How long can a diver stay underwater with one tank of oxygen?

An Average Diver, at an Average Depth, With an Average Tank Based on personal experience, an average open-water certified diver using a standard aluminum 80-cubic-foot tank on a 40-foot dive will be able to stay down for about 45 to 60 minutes before surfacing with a safe reserve of air still in the tank.

What happens if you dive with pure oxygen?

Divers breathing pure oxygen need to carry much smaller amounts of gas and produce no bubbles, but there are problems, some of which can be fatal. When a diver starts breathing from an oxygen rebreather the fraction of inspired nitrogen is zero.

Why oxygen is not used in oxygen cylinder?

Medical oxygen cylinders contain a high purity of oxygen gas; no other types of gases are allowed in the cylinder to prevent contamination. The industrial oxygen purity levels are not appropriate for human use and there could be impurities from dirty equipment or industrial storage that could make people ill.

Based on personal experience, an average open water certified diver using a standard aluminum 80-cubic-foot tank on a 40-foot dive will be able to stay down for about 45 minutes before surfacing with a safe reserve of air. What Factors Determine How Long the Air in a Scuba Tank Will Last?

How long does a 3000 psi oxygen tank last?
