Diving compressed gases (ie, scuba diving) can lead to two very serious medical conditions: Decompression Sickness (DCS), otherwise known as “the Bends,” and Pulmonary Over-Inflation Syndrome (POIS).
Is beginner scuba diving dangerous?

Is 40 feet deep for scuba diving?
A shallow dive is usually between 30 to 40 feet. Diving this shallow has many benefits such as increased visibility and dive time is limited only by air consumption. On a deep dive your bottom time is limited because of nitrogen absorption, additionally air consumption increases at depth because of ambient pressure.
Is scuba diving dangerous at 30 feet?
Scuba diving is dangerous at 30 feet, but the risks at this depth are minimal compared to most dives. This is a relatively shallow depth, and it carries lower chances of issues such as decompression sickness, nitrogen narcosis, or running out of air.

Don’t worry – beginner scuba divers can safely dive down to depths of 18 meters (60 feet) or more, which is one of the most common depths for many a dive site. Light also drops as you descend, the water preventing the sun’s rays from getting to you.

What is no stop time in scuba diving?

What is the golden rule of scuba diving?
1. Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls.
What happens if you stop breathing while scuba diving?
Overexpansion of the lungs can also lead to air bubbles in your bloodstream or too much pressure on your heart, both of which can be fatal if not corrected. There are no good reasons to hold your breath on a dive, so don’t let yourself get into the habit!
What is the number one rule for diving?
