Safety while diving

Dive only after taking in air deeply a number of times, and only when mentally and physically in perfect shape; after a meal wait at least 4 hours.

Only dive when tied to an underwater marking buoy visible from 300 m.

Do not dive alone, but in groups so as to allow to dive in turns, while your partner can check on you at the surface while you are under.

Communicate to family or friends the location where you are going to dive, as well as the planned time of return, and if possible procure the aid of a boat.

Have a full health check by a specialist at least once a year.

Do not wear lead belts that are so heavy as to pull you down too strongly.

Your gravitational balance must be slightly upwards.

Follow a class in first-aid, and pass a test for safety-swimming.

Dive against the tow, so as to use the current in case you are tired.
