The non-respect of these instructions can expose you to dangers leading to serious consequences on your
health.
Preamble
The scuba diving is a risky activity if done without knowledge of safety rules. You will find in this document the main tips
to follow and avoid to make your dives enjoyable leisure time. Other tips may be given by qualified diving instructors.
Rules & basics advises
Prior to diving, it is highly advisable to consult your doctor to assess your fitness to dive.
If you suffer from cardiovascular disease, asthma, diabetes, heart disease or vascular, ENT diseases, epilepsy and other
neurological disorders, scuba diving practice is strongly discouraged. It also applies to transient diseases such as colds,
sinusitis, bronchitis, infection of the nose, throat, ears (otitis) or teeth (caries).
Other factors must also make you give up scuba diving as peptic ulcer disease, retinal detachment, glaucoma, enlarged
spleen (splenomegaly) or pregnancy.
You will find in Annex a (french) document of the FFESSM (French CMAS) with a more complete list of contra-
indications.
Do not fly and avoid ride in altitude the same day of diving.
Throughout the dive, you need to adopt a continuous breathing while regularly checking your manometer
gauge.
Do not use earplug, they prevent pressure equalization.Dive only if you feel good and you feel like it, hydrate yourself
before and after the dive (to avoid drying up the mucous membranes with the cool and dry air)
The descent
The descent (even shallow) leads to an increase of the ambient pressure. To maintain a level of equal pressure between
you and the environment, you have to do the maneuver of Valsalva. This process involves blowing (slowly) while holding
your nose pinched and your mouth shut. By performing this operation you avoid the main risk during the descent :
barotrauma, which exerts its effects on the eardrums and sinuses mainly.
If you can't do this procedure correctly, you should't go deeper, ascend slowly to the surface.
The ascent
During the ascent, you have to do the maneuver of Toynbee, simply pinch your nose but this time swallowing (swallowing
saliva).
Pulmonary overpressure accident is one of the most serious dive accident, it occurs when the diver stops
breathing during an ascent. To avoid this, simply adopt a flexible and continuous breathing.
The diver's ascent speed mustn't be faster than the small air bubbles.
For experienced users and graduates of an accredited center, the ascent of a significant depth may require
decompression according to the dive time and the depth reached. The goal is to remove nitrogen accumulated in your
body, if you ascend too quickly, the nitrogen will not be eliminated. Worse, gas bubbles of blood-borne risks to block
some vessels, it can cause among other risk paralysis or thrombosis.
Any pain or discomfort during ascent or descent should get you to stop your progress. Go slowly and gradually to the
surface while controlling the pressure of your tank and your
breathing.
