Question: should i try to make homemade scuba gear?

( Back )

Answer #1:

One word "don't"!
Take a proper PADI driving course, and rent equipment from a proper dive store.
Only a special compressor can compress breathable air. Most off the self compressors introduce contaminants such as oil into the air. You don't want to breath oily air.
A air tank with out a regulator will blow out it's air in only a minute or so. The air pressure from your hookah will probably be too much and damage your lungs. 100's of hard hat divers died before the modern regulator was invented, doing stupid stuff like this. Take a Padi dive course.

Answer #2:

You play with your life by doing this, it's suicidal. Diving is a dangerous sport, and it is absolutely necessary to take courses in order to learn diving. There are precise rules to be strictly followed. The main danger is the difference of pressures that your body goes through by diving, and the effect this has on the gaz-concentrations in your blood. There are many dangers, so please don't make your homemade thing.

Answer #3:

Nope, you are risking significant injury by attempting this. Quite possibly a fatal injury.

The main issue you are risking is lung overexpansion leading to ruptured lung tissue, either from the unregulated flow of air from the pressurized cylinder (as already noted) or from your uneducated intent to hold your breath after filling your lungs with air at depth. Once your lung tissue ruptures, the air bubbles that escape could result in injuries such as a collapsed lung or an air embolism, either of which is a significant problem and an air embolism is often fatal.

As already suggested, you should obtain training from a recognized scuba training organization before attempting to breathe compressed air underwater. Not understanding the risks of breathing compressed air carries a significant risk of injury or death along with it.

As an aside - both NAUI and CMAS have a longer, more distinguished history than PADI. Perhaps it is the PADI marketing machine in action, but I find it annoying when "PADI dive course" is used as substitute for "scuba certification course".

Answer #4:

The dangers include:
* air embolism—puncturing lungs or circulatory system by over-pressurizing
* air contamination, particularly with hydrocarbons, carbon monoxide, nitrous oxides, and other, really nasty poisons which come from compressor lubrication
* lung overexpansion
* decompression sickness, a stealthy disease which can occur from rapid ascents from most any depth, as well as long dives at moderate depths, and short times at greater depths.
* sinus squeeze
* mask squeeze
* eardrum blowout
* drowning
* panicking
* nitrogen narcosis

Note that several of these can permanently injure or kill you. Just because it's easy to go underwater with air doesn't mean it's easy to get out safely.

The easiest way to learn about scuba topics is to enroll in an open water scuba class.
