no. oxygen and pressure is a lethal combination... 400ft has just to much pressure..
you will need nitrous to dive that deep... which is very dangerous.
Addition
Yes, technical divers can dive to 400 feet. But they do not breathe pure oxygen (or nitrous on the bottom). They breath a combination of helium, oxygen and nitrogen known as trimix.
Yes, it is possible for a human being to dive to 400 feet with the use of specialized equipment such as mixed gases and technical diving techniques. However, diving to such depths requires extensive training, experience, and equipment to manage the associated risks of deep diving, such as nitrogen narcosis and decompression sickness.

Scuba tanks have wh at noble gas in them?
Scuba tanks are typically filled with compressed air, which is a mixture of oxygen and nitrogen. However, some scuba tanks may also contain a noble gas such as helium as part of a special gas mix called trimix, which is used for deep dives to reduce the risk of nitrogen narcosis.
What is the altitude in meters or feet above which the recreational dive planners should not be used unless special procedures are followed?
The altitude above which recreational dive planners should not be used without special procedures is 300 meters (1000 feet). At higher altitudes, the partial pressure of oxygen changes, affecting the dive tables' accuracy, so adjustments must be made to ensure safe diving practices.
Which is better Steel or aluminum dive tanks?
Steel tanks are generally heavier than aluminum tanks but hold more air at higher pressures, making them more suitable for deep dives or technical diving. Aluminum tanks are lighter and more buoyant, making them easier to transport and suitable for recreational diving. The choice between the two depends on your diving needs and preferences.
How many gallons of water are in Epcot's Dive Quest?
The Dive Quest saltwater aquarium contains 5.7 million gallons.
How do scuba divers sink if they have tanks of compressed air on their backs?
Scuba divers use weights to sink during a dive because the air tanks on their backs make them buoyant. By adjusting the amount of weight, divers can achieve neutral buoyancy underwater. This allows them to control their depth and movement throughout the dive.
How deep can a person dive with helium-oxygen air tanks?
It depends on the percentage of the mixture You can adjust the percentage depending on desired depth and length of dive.
What can be purchased at a dive shop?
A dive shop sells all the required components for one to go underwater diving. They sell wetsuits, oxygen tanks, masks, fins, snorkels and accessories.
What is a two tank dive?
A dive that requires two tanks of air to complete
How can submarines float and sink?
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
What is the purpose of a submarine's ballast tanks?
to keep the sub level or help it to dive and surface
How does a submarine dive under water from the surface?
Submarines dive by opening vent valves that allow sea water to push air out of their ballast tanks.
How far can you scuba dive before you would die?
The world record for a scuba dive (without protective gear, beyond a wet suit and oxygen tanks) is approximately 1029 feet. The immense pressure which builds exponentially as an object descends is sufficient to crush humans at a lesser depth, in many instances.
Can you scuba dive with a pure oxygen tank?
No.
Did Hitler use blitzkrieg to invade Poland?
Yes - Junkers dive-bombers and massed tanks.
How much do aluminum dive tanks weigh?
The standard 80 weighs about 32 pounds empty.
How do you filling pressure in Breathing appratus?
If you mean Scuba tanks, call a dive shop, if you mean emergency breathing tanks, call your local Fire Co.
Scuba tanks have wh at noble gas in them?
