  • Supervised Dive
    EFFECTIVE 1 March 2009 MINIMUM COURSE CONTENT FOR Supervised Diver Certifi cation As Approved By ©2009, Recreational Scuba Training Council, Inc. (RSTC) Recreational Scuba Training Council, Inc. RSTC Coordinator P.O. Box 11083 Jacksonville, FL 32239 USA Recreational Scuba Training Council (RSTC) Minimum Course Content for Supervised Diver Certifi cation 1. Scope and Purpose This standard provides minimum course content requirements for instruction leading to super- vised diver certifi cation in recreational diving with scuba (self-contained underwater breathing appa- ratus). The intent of the standard is to prepare a non diver to the point that he can enjoy scuba diving in open water under controlled conditions—that is, under the supervision of a diving professional (instructor or certifi ed assistant – see defi nitions) and to a limited depth. These requirements do not defi ne full, autonomous certifi cation and should not be confused with Open Water Scuba Certifi cation. (See Recreational Scuba Training Council Minimum Course Content for Open Water Scuba Certifi ca- tion.) The Supervised Diver Certifi cation Standards are a subset of the Open Water Scuba Certifi cation standards. Moreover, as part of the supervised diver course content, supervised divers are informed of the limitations of the certifi cation and urged to continue their training to obtain open water diver certifi - cation. Within the scope of supervised diver training, the requirements of this standard are meant to be com- prehensive, but general in nature. That is, the standard presents all the subject areas essential for su- pervised diver certifi cation, but it does not give a detailed listing of the skills and information encom- passed by each area.

One statistic that about four fifths of drowning cases in which lung water and fifth left lung drowning but no water. The sink in water but not stuffy provincial time saved is called a near drowning. The reason for that condition in the lungs of drowning without water is not due to an unexpected swim under water, causing the victim to panic disorder to reflect the body was submerged, reflex muscle contraction epiglottis airways and closed again as the victim is not breathing hypoxic brain and lead to unconsciousness. Epiglottis is closed due to water entering the lungs is not. It is also called dry drowning. Emergency drowning victims: - When you see a panicky hurry on the water for them anything that can help them cling and float up. If only one and two hands, if not an emergency personnel are experienced swim out and rescue personnel is very risky even a good swimmer because of extreme panic, victims often tend to struggle, cling very tightly making it difficult for the emergency and the risk of drowning is always both.
